How to identify a phone model when there's no box
Five reliable ways to pin down exactly which handset is on your bench, including the variant markings that decide which part actually fits.

A customer hands you a cracked phone and says it's "a Vivo". No box, no receipt, and the back of the case has worn smooth. Before you can order a single part you need the exact model — and often the exact variant, because a 4G and a 5G version of the same name can take different glass.
Here are the methods that work, roughly in order of how quickly they get you an answer.
1. The settings menu, if the phone still powers on
This is the fastest route and it works on every Android handset:
Settings → About phone
Look for two different things. The device name is the marketing name ("Redmi Note 11 Pro"). The model number is the manufacturer's internal code (2201116TG, V2111, SM-A525F). Write down both. The model number is the one that distinguishes variants, and it's what a supplier will recognise without argument.
On some skins the model number is buried one level deeper, under About phone → All specifications or Software information.
2. Dial *#06#
Typing *#06# into the dialler pops up the IMEI immediately — no menus, and it works even on a locked phone at the lock screen on most devices. You'll usually get the model number on the same screen.
The IMEI matters for a second reason: the first eight digits are the Type Allocation Code, which identifies the exact model as certified. If everything else fails, an IMEI lookup will tell you what you're holding.
3. Look under the SIM tray and on the frame
Pop the SIM tray out. Many manufacturers print the model number in the tray cavity or on the tray itself. Oppo and Realme are particularly good about this.
Also check:
- The bottom edge of the back cover, in very small print
- Under a removable back, on the chassis
- The regulatory label, often a block of tiny text near the bottom
Bring a loupe or use your own phone's camera zoom. This print is frequently below 4pt.
4. The screen itself tells you things
If the phone is dead and unlabelled, the display can still narrow it down:
- Notch shape. A teardrop, a hole-punch, and a wide notch each rule out large families of models.
- Hole-punch position. Centred versus left-corner is a hard distinction, not a stylistic one.
- Curvature. A flat panel and a curved-edge panel of the same nominal size take completely different glass.
- Bezel width. A thick bottom chin usually means a budget line.
Measure the screen diagonally, corner to corner of the active area, not the glass. Note it to one decimal place.
5. Ask the customer what they bought
Obvious, but worth saying: ask whether they bought the 4G or 5G version, and which region it came from. Customers rarely know the model number but often remember "the 5G one" or that it was bought abroad. Regional variants are a real source of fitment mismatches — the same marketing name can ship different panels in different markets.
Why the variant matters more than the name
This is the part most people underestimate. Consider what has to line up for a piece of tempered glass to sit correctly:
- the earpiece slot position
- the front camera cutout
- the active area, so touch still works at the edges
- the curvature, so the adhesive makes contact all the way round
- the exact diagonal, to within a millimetre
Two phones can share a marketing name, a screen size, and a general look, and still differ in one of those. That's why compatibility is tracked by part group rather than by screen size.
Once you have the model
Search it here and you'll get the part code that fits, plus every other model that same part covers. If a model turns out to match two different parts, we say so rather than guessing — those are the cases where measuring before you order saves a second trip to the supplier.
If a phone genuinely can't be identified, order nothing. A wrong part costs more in time and goodwill than an extra ten minutes with a loupe.
