Not sure which iPhone you have in 2026? Learn how to find your iPhone model number in Settings or identify it when your phone won’t turn on. Check the A-number, serial number, and model list to find your exact iPhone.
Not sure which iPhone you have? You can usually find the answer in just a few taps. The quickest iPhone model number check is inside the Settings app, where Apple shows your Model Name and Model Number. You can then use the A-series model number to identify the exact iPhone model and, where applicable, its regional variant.
You do not need to inspect the hardware, search through the original box, or remember what your iPhone looks like. And if your iPhone is powered off, damaged, or won’t turn on, there are other ways to find its model number.
Knowing your exact iPhone model can help you check iOS compatibility, accessories, replacement parts, repair information, resale value, and second-hand device details. Here’s how to find it.
How to Find Your iPhone Model Number in Seconds
The easiest way to perform an iPhone check model number is through Settings. Apple places the relevant device information together on the About screen.
Find Your iPhone Model Number in Settings
- Open the Settings app on your iPhone.
- Tap General.
- Select About.
- Look for Model Name and Model Number.
The Model Name tells you the iPhone you are using, such as an iPhone 13, iPhone 15 Pro, or iPhone SE. The value initially shown next to Model Number may look like a combination of letters and numbers rather than the A-number you may be expecting.
Tap the Model Number once. The displayed value will switch to the technical model number beginning with “A”, such as Axxxx. This is the identifier you can use to identify your iPhone model number and match your device with an iPhone model list.
What Does the iPhone A-Series Model Number Mean?
The A-series number is Apple’s technical identifier for a specific iPhone model and regional variant. For example, two versions of the same iPhone generation can have different A-numbers depending on the market they were made for or sold in.
This is why knowing the A-number can be more useful than simply knowing that you have an “iPhone 15” or “iPhone 16.” When checking accessories, replacement parts, repair information, or regional compatibility, the exact identifier can help you narrow down the correct version.
Important: The number you see before tapping Model Number is the part number, while the number that appears after tapping it is the A-series model number. Keeping these two identifiers separate makes an iPhone check model number much less confusing.
Once you have the A-number, you can compare it with the model-number reference list later in this guide to identify your iPhone model precisely.
How to Quickly Tell Which iPhone You Have
Finding an iPhone model number is only half the job. Once you have the A-series number, you can determine the exact iPhone model instead of relying on the phone’s appearance.
This matters because several iPhone generations can look similar, while their technical model identifiers are different.
Identify Your iPhone Using Its A-Number
After you reveal the A-series number in Settings > General > About, compare it with the corresponding model number in the complete iPhone model list below.
Each A-number is associated with a particular iPhone model and, in some cases, a particular regional version.
For example, if your iPhone shows an A-number such as Axxxx, search for that number in the list to find its matching iPhone model name. You can then confirm whether you have a standard, Plus, Pro, Pro Max, mini, or SE model.
Tip: Do not rely on physical appearance alone when trying to identify iPhone models. Similar-looking devices can belong to different generations, so the A-number provides a more precise way to confirm which iPhone you have.
The same approach is useful when checking a second-hand iPhone or ordering accessories and replacement parts. Once the A-number matches the correct entry, you have a much clearer answer to “How do I know what iPhone I’m using?” without having to guess from the design.
How to Find Your iPhone Model Number When It Won’t Turn On
What if your iPhone is powered off, has a damaged screen, or simply won’t boot? You can still identify it without opening Settings.
Depending on the model, Apple provides physical ways to locate the model number. These include the SIM-tray area, the back of older iPhones, or the USB-C or Lightning connector on iPhones without a SIM tray.
Check the Model Number Inside the SIM Tray
On an iPhone 8 or later model that has a SIM tray, the A-series model number can be engraved inside the SIM card slot. This is especially useful when the phone won’t turn on and you need to identify your iPhone model number from the hardware.
Start by removing the SIM tray with a SIM ejector tool. If you don’t have one, a straightened paperclip can work. Once the tray is out, look closely inside the opening, particularly along the upper side of the slot.
Use a flashlight if the engraving is difficult to see. The text is very small, so you may need to tilt the phone slightly to spot it.
Tip: The model number is easy to miss because it is very small and lightly engraved. Take your time and use a flashlight rather than assuming it is not there.
Once you find the A-number, compare it with the iPhone model number list later in this guide.
Find the Model Number on the Back of an Older iPhone
If you have an iPhone 7 or an earlier model, another simple option is to check the back of the device.
Remove the case or skin first so the text is visible. Then look near the bottom edge of the back for a small identifier beginning with “A.”
Important: This physical method mainly applies to older iPhone models. Newer iPhones moved away from printing the model number on the back, so do not assume that a missing number means something is wrong with your device.
After finding the A-number, match it with the appropriate entry in the model list to identify your iPhone model.
Check the Model Number Inside the USB-C or Lightning Connector
If your iPhone does not have a SIM tray, Apple provides another physical location to check: the USB-C or Lightning connector.
Look inside the connector and examine the upper side—the side with the display. Use bright light because the model number is very small.
This method is especially relevant for iPhones sold in markets where particular models are eSIM-only. SIM availability varies by model and region; for example, Apple currently lists several recent iPhone models as eSIM-only in the United States and several other markets.
Tip: If your iPhone has no SIM tray, don’t assume you have no way to find the hardware identifier. Check the USB-C or Lightning connector instead.
Check the Original iPhone Box for the Model Number
Don’t have access to the iPhone itself? Your original iPhone box may provide another way to identify the device.
Look for the barcode label on the packaging. Depending on the box and model, the label can include the device’s model information along with details such as the serial number and storage capacity.
Tip: If you’re identifying a used iPhone, checking the box is helpful, but compare its information with the device itself whenever possible. Packaging alone should not be the only basis for verifying a phone.
Find Your iPhone Model Number Using a Mac or Windows PC
A computer can also help when your iPhone is difficult to operate because of a broken or unresponsive display. Connect the iPhone to a Mac or Windows PC using a compatible cable.
On a Mac, open Finder and select your iPhone from the sidebar. On a Windows PC, use the supported Apple device software or iTunes, depending on your setup. Once the device is recognized, open its information page to view its identifying details.
The available device information can help you confirm the model name, model number, serial number, and IMEI.
Important: This method requires the computer to recognize the iPhone. If the device is completely unresponsive and cannot establish a connection, use the SIM tray, physical markings, or original box instead.
How to Find the Model Number on Your iPhone 5C
If you have an iPhone 5C and want to know its exact model number, you can find it directly through the Settings app. This is useful when you need to confirm the device before buying accessories, checking compatibility, or identifying an older iPhone.
Find the iPhone 5C Model Number
Open Settings on your iPhone 5C, then go to General > About. Look for the Model Number field.
On older iPhone models such as the iPhone 5C, the About page may display a model identifier rather than the full model name. Tap the value shown next to Model Number to switch it to the technical A-series number, which begins with the letter “A.”
Tip: The A-number is the identifier you should use when you need to identify your iPhone model precisely. Compare it with the iPhone model-number list later in this guide to confirm whether your device is an iPhone 5C.
Once you have the A-number, matching it against the reference list can also help distinguish the iPhone 5C from other older iPhone models that may have a similar design.
iPhone Model Number vs. Part Number, Serial Number and IMEI: What’s the Difference?
When you check Settings > General > About, you may see several different identifiers together. They can look similar at first, but each one serves a different purpose.
Understanding the distinction makes it easier to identify your iPhone model, provide information to Apple or a repair provider, and choose the right number when checking a used device.
What Is an iPhone Model Number?
The iPhone model number is the technical identifier used to distinguish a particular iPhone model and its regional version. When you tap the value beside Model Number in the About section, it switches to an A-series number that starts with the letter “A”, followed by four digits.
For example, an identifier may look like Axxxx. You can use this number to match your device with an iPhone model list and determine exactly which iPhone you have.
What Is the iPhone Part Number?
The part number is the identifier initially displayed next to Model Number before you tap it. It can contain a combination of letters and numbers and may include a regional suffix.
Tap the field once, and it changes to the A-series model number. This makes it important to distinguish between the two when someone asks you to provide your iPhone’s model number.
Important: The part number and A-series model number are not the same thing. The part number is the value initially displayed, while tapping it reveals the technical A-number used for model identification.
What Is an iPhone Serial Number?
The serial number is a unique identifier associated with your individual iPhone. Unlike the A-series model number, which can apply to many devices of the same model, the serial number distinguishes one particular device.
You can usually find it under Settings > General > About, and it may also appear in your Apple Account device list or on the original iPhone packaging.
This is the number you would typically need when you want to check the serial number of an iPhone rather than identify its general model.
Important: Your serial number does not tell you the general iPhone model by itself in the same way the A-series model number does. Use the appropriate identifier for the task you are trying to complete.
What Is an IMEI Number?
The IMEI is another unique identifier associated with an iPhone’s cellular hardware and network identity. It is different from both the model number and serial number and can be found in the About section on supported iPhones.
The IMEI is primarily useful when a specific device needs to be identified for cellular, carrier, or support-related purposes.
Keep in mind: The model number identifies what iPhone you have, while the serial number and IMEI identify the individual device.
How to Check the Serial Number of Your iPhone
Your iPhone serial number is different from the model number. While the model number helps you determine which iPhone model you have, the serial number is tied to the individual device.
There are several places you can look for it, including your iPhone’s Settings, Apple Account, original packaging, or a connected computer.
Find Your iPhone Serial Number in Settings
The easiest way to check serial number of iPhone is through the same About page used to find your model information.
Open Settings > General > About, then scroll through the device details until you find Serial Number. You can press and hold the number to copy it when you need to enter it somewhere else.
This method is especially convenient because the serial number appears alongside other information, including the Model Name, Model Number, and IMEI.
Tip: If you’re copying your serial number for a support request or device check, use the copy option instead of typing the long identifier manually.
Find Your Serial Number Through Your Apple Account
You can also look up an iPhone’s identifying information through the Apple Account connected to the device.
On your iPhone, open Settings and tap your name at the top. Scroll through the list of devices associated with your Apple Account and select your iPhone. Depending on the device information available there, you can view details such as the model name, serial number, and IMEI.
This can be particularly useful when you cannot conveniently navigate through the iPhone itself.
Find Your Serial Number on the Original iPhone Box
If you no longer have access to the phone, check the original iPhone box. The barcode label can contain the device’s serial number, along with other identifying information.
Look for the label on the packaging and compare the serial number with the records available for the device.
Important: The original box is useful for finding a serial number when the iPhone is unavailable, but for a used device, it is better to compare the box information with the iPhone itself whenever possible.
Check Your Serial Number Using a Mac or Windows PC
When your iPhone can connect to a computer but is difficult to use directly, you may also be able to view its identifying information from the computer.
Connect the iPhone to a Mac and open Finder, then select the device from the sidebar. On Windows, use the applicable Apple device software or iTunes and select your iPhone.
The device information screen can provide identifiers such as the serial number, model information, and IMEI, depending on the connection and software being used.
Keep in mind: A serial number identifies your specific iPhone, while the A-series model number identifies the hardware model.
How to Tell If Your iPhone Is Original or Fake
Trying to check if an iPhone is real can be especially important when you’re buying a used device or receiving one from an unfamiliar seller.
A model number, serial number, or IMEI can give you useful information, but no single identifier should be treated as absolute proof that an iPhone is genuine.
The better approach is to compare the information shown by the device with its physical hardware and other available records.
Check If Your iPhone Is Real Using Its Model Number
Start with the A-series model number found under Settings > General > About. After tapping Model Number, you’ll see a number beginning with “A” followed by four digits.
Search for that A-number in the official iPhone model list and check whether it corresponds to the model shown on the device.
For example, if the phone claims to be a particular iPhone generation but its A-number belongs to a different model, that is a clear reason to investigate further.
Important: An A-number can help you identify iPhone model number, but matching an existing number does not, by itself, prove that every component inside the device is original.
Check Your iPhone Serial Number
Next, check serial number of iPhone to compare the individual device identifier with information associated with it.
You can find the serial number in Settings > General > About, through your Apple Account device list, on the original packaging, or through a connected Mac or Windows PC.
A serial number that does not match the device records or other available information can be a warning sign, particularly when buying a second-hand iPhone.
Tip: When you’re trying to look up an iPhone serial number, compare the identifier from more than one source whenever possible instead of relying only on the number printed on a box.
Look for Other Signs That Your iPhone Is Genuine
Model and serial information are useful, but you should also look at the phone itself. Check whether the Model Name, hardware design, ports, buttons, camera layout, and other physical characteristics match the model identified by the A-number.
You can also open the Settings app and review the information shown under General > About.
If you’re checking a device received from someone else, inconsistencies between the model number, serial number, software information, packaging, and physical design deserve closer attention.
How to Check If an iPhone Is Legit Before Buying Used
Before paying for a used iPhone, take a few minutes to perform an iPhone model number check and compare what you see on the device with what the seller claims.
Confirm the Model Name, reveal the A-series model number, and check the serial number. Then compare the phone’s physical appearance and identifying information with the claimed model.
Important: If the seller’s description, model number, serial number, packaging, or physical device details do not line up, do not assume the phone is genuine simply because it looks like an iPhone.
How to Check an iPhone’s Original Country Using Its Model Number
Want to know which market your iPhone was intended for? The model number can provide useful clues about its regional version, especially when the same iPhone model was sold with different A-numbers in different countries or regions.
Check the iPhone Model Number for Its Country or Region
Start by finding the A-series model number in Settings > General > About. Tap the value beside Model Number until it changes to the identifier beginning with “A.”
Once you have the A-number, compare it with the regional entries in the iPhone model number list. You may find that the same iPhone model has several A-numbers, with each one associated with a different market.
For example, an iPhone model can have one A-number for the United States, another for Canada or Japan, and additional variants for China, Hong Kong, Macao, or other regions.
Tip: An iPhone model number check country lookup can help you identify the sales region or regional variant of your device, but the A-number should not automatically be interpreted as the country where the iPhone was physically manufactured.
Does an iPhone Model Number Show Where It Was Made?
Not exactly. The iPhone model number is primarily used to identify the hardware model and its regional version. It can help you determine the market a particular device variant was designed for, but that is different from knowing where the device was actually assembled.
This distinction matters because people often search for “check iPhone original country by model number” expecting the A-number to reveal a manufacturing country.
Instead, it is more accurate to think of the model number as a way to identify the iPhone model and regional configuration.
Important: When checking an iPhone’s origin, distinguish between its regional sales variant and its physical manufacturing location. A model number can help with the first, but it does not necessarily tell you the second.
Complete iPhone Model Number List
Found the A-number but not sure which iPhone it belongs to? This list lets you identify your iPhone model number by matching the number shown on your device with the corresponding iPhone model.
Use the Model Number shown in Settings > General > About and tap it once to reveal the A-series number. Then search for that number in the list below.
Tip: If you see several A-numbers listed for the same iPhone, they can represent different regional variants of that model. Match the exact A-number on your device rather than choosing the first one you see.

Important: The model list is useful for identifying your iPhone models, but regional A-number differences mean that the same iPhone name can have more than one model number. For the most accurate identification, always match the exact A-number shown on your device with the applicable regional listing.
What Do the Numbers on an iPhone Mean?
When you open Settings > General > About, you may notice several different numbers and identifiers listed together. They can look similar at first, but each one serves a different purpose.
What Is the A-Series Model Number?
The A-series model number is the technical identifier used to identify a specific iPhone model and its regional version. It starts with the letter “A” followed by four digits, such as Axxxx.
You can reveal this number by opening Settings > General > About and tapping the value shown next to Model Number. Once it changes to the A-series format, you can use it to match your phone with the iPhone model number list.
Tip: When you need to identify iPhone model number, look for the A-number rather than assuming the first value shown in the Model Number field is the one you need.
What Is the iPhone Part Number?
The part number is the identifier initially displayed next to Model Number in the About section before you tap it. It can contain a combination of letters and numbers and may include a regional suffix.
Tap the field once, and it changes to the A-series model number. This makes it important to distinguish between the two when someone asks you to provide your iPhone’s model number.
Important: The part number and A-series model number are not the same thing. The part number is the value initially displayed, while tapping it reveals the technical A-number used for model identification.
What Is the iPhone Serial Number?
The serial number is a unique identifier associated with your individual iPhone. Unlike the A-series model number, which can apply to many devices of the same model, the serial number distinguishes one particular device.
You can usually find it under Settings > General > About, and it may also appear in your Apple Account device list or on the original iPhone packaging.
This is the number you would typically need when you want to check the serial number of an iPhone rather than identify its general model.
What Is the iPhone IMEI?
The IMEI is another unique device identifier associated with an iPhone’s cellular hardware. It is different from both the model number and serial number and can be found in the About section on supported iPhones.
The IMEI is primarily useful when a specific device needs to be identified for cellular, carrier, or support-related purposes.
Keep in mind: The A-series model number tells you what iPhone model you have, while the serial number and IMEI identify the individual device.
