The fastest way: check your Settings app

Open Settings on your tablet, then tap About tablet (or About device on older models). The screen that opens shows your model name and number. Look for a line that says Model or Device name — this is what you need if you're looking up specs, buying a case, or troubleshooting a problem.

The model number usually looks like "SM-T870" or "SM-X700" — a two-letter prefix followed by a hyphen and four digits. This number is the most reliable identifier because it's the same across all regions, whereas the marketing name (like "Galaxy Tab S9") can vary by country.

If you can't find the About section, swipe down from the top of the screen twice to open Quick Settings, tap the gear icon, then scroll to the bottom of the Settings menu and look for About.

Key Takeaways

  • Your tablet's model number appears in Settings > About tablet, and it's the most reliable way to identify your exact device.
  • The model number format is usually two letters, a hyphen, and four digits (like SM-T870), and this stays the same no matter what country you're in.
  • If you've lost access to the tablet itself, the model number is printed on the back of the device or on the original box and receipt.
  • Knowing your exact model helps you find the right case, charger, software updates, and repair parts.

Where to find the model number on the physical tablet

If your tablet won't turn on or you can't access Settings, the model number is printed on the back of the device. Look for small text near the bottom — you'll see "Model:" followed by the code. On some older Galaxy Tab models, this information is on a sticker inside the SIM card slot (if your tablet has one).

The back of the tablet also shows the serial number, which is different from the model number. The serial number is unique to your device, while the model number identifies the type. You need the model number for almost everything — cases, chargers, software — so focus on that.

Check the original box and paperwork

If you still have the box your tablet came in, the model number is printed on the outside. Look on the side or back panel where the barcode is — Samsung lists the model prominently there. The receipt or invoice from your purchase also shows the model name, though sometimes only the marketing name (like "Galaxy Tab S9 Ultra") rather than the technical model number.

If you bought the tablet from a carrier like Verizon or AT&T, your account page online may also show the device model under your line details.

Understanding Samsung's tablet naming system

Samsung uses two different names for the same tablet: a marketing name and a model number. The marketing name is what you see in ads — "Galaxy Tab S9" or "Galaxy Tab A7" — and it's easier to remember but less precise. The model number (SM-T870, for example) is what you need when you're buying accessories or looking up technical specifications.

The "Galaxy Tab" line includes several sub-series: the S-series (premium tablets with high refresh rates), the A-series (mid-range), and the FE (budget-friendly). Within each series, numbers indicate the generation — Tab S9 is newer than Tab S8. But the model number tells you everything at once, so it's always the safer choice when you're researching your device.

What to do once you know your model number

Once you have the model number, you can search Samsung's official support website to find the exact specs, battery capacity, screen size, processor, and how much storage your tablet has. You can also check which Android version it shipped with and whether it's still receiving security updates.

The model number also helps you find the right accessories. A case or screen protector designed for the Tab S9 won't fit the Tab A7, even though both are Samsung tablets. Chargers are similar — some Samsung tablets use USB-C, others use older connectors, and the wattage varies. Knowing your model prevents you from buying the wrong thing.

If you need to send your tablet for repair, the technician will ask for the model number. If you're selling it, listing the model number (not just "Samsung tablet") helps buyers know exactly what they're getting.

If you see multiple model numbers

Sometimes you'll find more than one model number on your tablet. The main model (like SM-T870) is what you use for identification. You might also see a regulatory number (FCC ID) or a carrier-specific variant code — these are for technical and legal purposes, but they don't change which case or charger fits your device. Stick with the main model number starting with "SM-".

If your tablet was sold by a carrier, there may be a carrier-specific suffix on the model number — for example, "SM-T870U" for unlocked or "SM-T870V" for Verizon. These variants have minor differences in software or radio bands, but they're still the same tablet for the purposes of buying a case or finding repair guides.

Frequently Asked Questions

Where is the model number if my tablet is in a case?

Remove the case and look at the back of the tablet. The model number is printed directly on the plastic or metal back panel, usually near the bottom. You can also find it in Settings > About tablet without removing the case.

Is the serial number the same as the model number?

No. The model number identifies the type of tablet (like SM-T870), while the serial number is unique to your individual device. You need the model number for cases, chargers, and specs. The serial number matters for warranty claims and theft recovery.

Can I find my tablet's model if I sold it or lost it?

Yes, if you have the original box, receipt, or invoice. The model is printed on the box and listed on your purchase receipt. If you bought it from a carrier, your account history online may also show the model under your device details.

Do all Samsung tablets with the same marketing name have the same model number?

Not always. Carrier variants (Verizon, AT&T, T-Mobile) sometimes have different model numbers for the same "Galaxy Tab" name. The main model number is the same, but there may be a letter suffix. This matters for software updates but not for cases or chargers.

What if the model number on the back is worn off or unreadable?

Go to Settings > About tablet — the model number there is always readable. If your tablet won't turn on, try the original box or receipt. If you have none of these, a Samsung service center can identify your device by the serial number on the back.
