iPhone 13 Pro Max IMEI Check: Read the Tray, Then the Lock
The 13 Pro Max still carries its IMEI on the SIM tray, which makes tampering easy to spot. Here is what to match, and how rarely these phones read unlocked.

The tray is a tamper test
Apple released the iPhone 13 Pro Max in 2021 with 128 GB, 256 GB, 512 GB and 1 TB. On Apple's "Identify your iPhone model" page (read 10 November 2026) it is listed with a SIM tray on the left side for every region, and with the IMEI etched on that tray. Newer iPhones sold in the United States dropped the tray, so this is one of the last generations where the number can be read off the metal.
That gives a buyer a simple test. Eject the tray, read the etched number, and compare it to Settings, General, About. A mismatch means the tray came from another phone, which happens after repairs and sometimes after theft.
| A-number | Sold in | Checked on FullIMEI (90 days) |
|---|---|---|
| A2484 | United States | 221 devices |
| A2643 | Other countries and regions | 11 devices |
| A2641 | Canada, Japan, Mexico, Saudi Arabia | under 10 |
| A2645 | Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia | under 10 |
| A2644 | Mainland China, Hong Kong, Macao | under 10 |
The counts cover 12 August to 10 November 2026 and count each handset once. Rows under ten are hidden rather than rounded.
One unlocked phone in twenty
The lookup read a lock on 66 of the 221 A2484 phones: 55 locked and 11 unlocked. The remaining 155 are unknown, meaning no carrier we read was found, which is not a clean bill of health.
| A2484 result | Devices | Share of 221 |
|---|---|---|
| Locked to a carrier we read | 55 | 25 % |
| Unlocked | 11 | 5 % |
| Unknown (lock not readable for free) | 155 | 70 % |
Among the readings we could take, five locked phones turned up for every unlocked one. Compare the 13 Pro Max with the plain iPhone 13, where locked outnumbered unlocked by a wider margin, and with the newer 14 Pro Max, which sits at 8 % unlocked.
Where the checks come from
Lookups for the US build were typed in from Pakistan (53), the United States (46), Mexico (15), Nigeria (13) and the Dominican Republic (11). Nigeria appears here with 13 devices, while the iPhone 14 Pro Max page has no Nigeria row. A US-build phone checked in a country that does not sell it is normally a used import, and importers are the people most likely to meet a locked unit.
Four things to do before you hand over money
- Pull out the SIM tray and read the etched IMEI; then open About and compare. They must match digit for digit.
- Look at Model Number in About. A leading "M" means retail, "F" refurbished, "N" a replacement unit, "P" personalised: Apple's own convention for the first letter of that code.
- Ask for the 1 TB or 512 GB price in writing if the listing quotes a large size; those are the models with the biggest balances.
- Run the lookup, then read the unlock page if it reports a lock.
Model numbers and the tray detail are Apple's; every count is our own and will move. A clean blacklist result says nothing about whether a plan is paid off.
Questions people ask
Where is the IMEI on an iPhone 13 Pro Max?
Apple says the IMEI is etched on the SIM tray. It is also in Settings, General, About, and dialling *#06# shows it. If the tray number and the screen number disagree, the tray or the board has been swapped.
What are the model numbers for the iPhone 13 Pro Max?
Apple lists A2484 for the United States, A2641 for Canada, Japan, Mexico and Saudi Arabia, A2644 for mainland China, Hong Kong and Macao, A2645 for Armenia, Belarus, Kazakhstan, Kyrgyzstan and Russia, and A2643 for other countries and regions.
Which storage sizes exist for the iPhone 13 Pro Max?
Apple lists 128 GB, 256 GB, 512 GB and 1 TB. The 1 TB version is the dearest, so it is the one where an unpaid balance costs most.
Can I see if a 13 Pro Max is carrier locked for free?
Only when it is tied to T-Mobile or Metro. Of 221 US-build units checked in the last 90 days, 66 returned a lock reading and 155 came back unknown.
Is the iPhone 13 Pro Max still worth buying used?
That depends on price and battery health more than on the IMEI. What the IMEI settles is whether the phone is the model advertised, whether it is blacklisted, and what lock it carries.
