Where to Find Your Model Number on Your Phone

The fastest way to find your Samsung model is to open Settings, tap About phone, and look for the line that says Model name or Model number. This is the official identifier Samsung uses, and it will be something like SM-G991B or SM-A125F. Write it down or take a screenshot — you'll need this exact number if you're ordering parts, checking software updates, or troubleshooting with Samsung support.

If your phone won't turn on or Settings won't open, you can find the model number printed on a label inside the battery compartment (if your model has a removable battery) or on the back of the phone near the bottom. Some Samsung phones also print it on the SIM card tray — eject the tray with a pin and look at the label underneath.

Key Takeaways

  • Your model number appears in Settings under About phone, and it starts with "SM-" followed by a letter and numbers.
  • The model number is different from the marketing name — a Galaxy S24 Ultra has a model number like SM-S928B.
  • You can also find the model printed on a physical label on your phone's back, SIM tray, or original box.
  • The IMEI number (15 digits, found by dialing *#06#) identifies your specific phone but is not the same as the model number.

Understanding Model Numbers vs. Marketing Names

Samsung uses two different naming systems, and they're straightforward to confuse. The marketing name is what you see in ads and on the box — Galaxy A15, Galaxy S24, Galaxy Z Fold 6. The model number is the technical identifier that starts with SM- and includes regional variants. A Galaxy S24 sold in North America might be SM-S921U, while the same phone sold in Europe is SM-S921B.

The regional letter at the end matters because it tells you which network bands your phone supports and which software version it runs. If you're looking up repair guides, checking compatibility with accessories, or contacting support, always use the full model number including the regional code. The marketing name alone won't give a technician enough information.

Reading the Label on Your Phone or Box

If you have your original Samsung box, the model number is printed on the back or side, usually near a barcode. Look for text that says "Model:" followed by the SM- code. The box label is often clearer and easier to read than trying to find it on the phone itself, especially if the phone's back label has worn away.

On the phone itself, look at the back panel near the bottom, where you'll see small printed text. Some newer Samsung models have the information on the SIM card tray — remove the tray by inserting a SIM ejector tool or straightened paperclip into the small hole on the side of the phone, then check the label on the tray itself. The text is small, so good lighting helps.

Using the IMEI Number to Cross-Check

Your phone also has an IMEI number, which is a 15-digit code unique to your individual device. You can find it by opening the Phone app, pressing the keypad, and dialing *#06# — the IMEI will appear on screen without you having to press call. You can also find it in Settings under About phone, or printed on the SIM tray.

The IMEI identifies your specific phone (like a serial number), while the model number identifies the type of phone. If you're checking whether a used Samsung is authentic or looking up warranty information tied to your device, you'll need the IMEI. But for finding repair manuals, software updates, or accessory compatibility, the model number is what you need.

What to Do If You Can't Find the Model Number

If your phone is damaged, won't power on, or the labels are worn away, contact Samsung support with your phone's IMEI number or your account information. Samsung can look up your device history and tell you the exact model. You can reach Samsung through their website, by calling their support line, or by visiting a Samsung service center with your ID and proof of purchase.

Another option is to check your carrier's account online — Verizon, AT&T, T-Mobile, and other carriers keep a record of every device on your account, including the model number. Log into your account on their website or call customer service with your phone number, and they can tell you the model in seconds.

Common Model Number Formats and What They Mean

Samsung model numbers follow a pattern: SM- followed by a letter (usually G, A, Z, or F) and four digits, then a regional code. The letter tells you the product line — G is Galaxy, A is Galaxy A series, Z is foldable phones, F is Galaxy F series. The four digits narrow it down further. For example, SM-G991B is a Galaxy S21, while SM-A125F is a Galaxy A12.

The final letter is the regional variant. U means United States, B means Europe, C means Canada, and so on. This matters because it affects which 4G and 5G bands your phone can use, which carrier it's locked to (if any), and which software updates it receives. If you're buying a used phone or ordering parts, always match the full model number including the regional code.

Frequently Asked Questions

Is the model number the same as the serial number?

No. The model number (SM-G991B) tells you what type of phone it is. The serial number is unique to your individual device and appears on the back label or in Settings under About phone as "Serial number." Both are useful, but for different reasons — use the model number for repairs and software, the serial number for warranty claims.

Why does my model number have a different regional code than my country?

Your phone was likely purchased in a different region or imported. The regional code is set when the phone is manufactured and doesn't change. This is normal and usually doesn't cause problems, but it means your phone may receive software updates on a different schedule than phones sold locally, and some carrier features might not work.

Can I change my phone's model number?

No. The model number is burned into your phone's hardware during manufacturing and cannot be changed without replacing the motherboard. If someone claims they can change it, they're either mistaken or selling you a counterfeit phone.

What if my Settings app shows two different model numbers?

This is rare but can happen if your phone has been repaired with a replacement part. Check the physical label on the back or SIM tray — that's the authoritative source. If they don't match, contact Samsung support, as it may indicate a repair issue.

Do I need the model number to update my Samsung phone?

No. Your phone automatically checks for updates in Settings under Software update, and it downloads the correct version for your specific model and region. Knowing your model number is helpful if you're troubleshooting an update problem or looking up release notes, but you don't need it to update normally.
