Where a OnePlus keeps the number
| Where | What to do | Catch |
|---|---|---|
| Dialer | Enter *#06#. | Two numbers on dual-SIM models. |
| Settings | Settings, About device, then the SIM or status page. Some versions show IMEI right on the main About screen. | The path moved between OxygenOS versions. |
| Box label | The sticker lists IMEI 1, IMEI 2 and the model number. | Boxes are reused. |
| SIM tray | Several models print a code on the tray. | Often too small to read. |
| Order page | The shop account or OnePlus store order may list it. | Original buyer only. |
Model prefixes and what they tell you
OnePlus model numbers changed their pattern over the years, and the pattern is a free clue about which region a phone was built for. Older models used a letter and digits. From the 7 series onward the letters usually carried the region, and the newest global models moved to the same CPH numbering used by Oppo. A phone whose number does not fit the pattern of its name deserves a question to the seller.
| Pattern | Looks like | Usually means |
|---|---|---|
| Letter + 4 digits | A6013 | An early OnePlus, before the 7 series. |
| Two letters + 4 digits | GM1913, IN2023, KB2003, LE2123, NE2213 | A 7 to 10 series phone, with the letters pointing at the region or carrier version. |
| CPH + 4 digits | CPH2449 | A newer global model. |
| Other prefixes | PJ and similar | Often the China-market version; check bands and software before buying. |
The table is a guide to patterns, not a database. Use the number with the compatibility page to see whether the bands suit your network.
Carrier versions of a OnePlus
OnePlus built its reputation on selling unlocked phones directly, but some models were also sold through US carriers, including T-Mobile and its prepaid brand Metro. A carrier version can carry a lock and different software. Our checker answers lock questions for T-Mobile and Metro by T-Mobile, which fits those models; the unlock page covers the rest.
A buyer's checklist for a second-hand OnePlus
- Dial *#06# with the seller watching. Write down every number.
- Open About device and compare the model number with the box and listing.
- Enter the first IMEI in the checker above.
- Run it on the blacklist page.
- Ask the seller to remove the Google account, then reset the phone in front of you.

Questions people ask
What is the number on my OnePlus that looks like CPH or NE?
It is the model number. Older OnePlus phones use letters like A, GM, HD, IN, KB, LE or NE with digits; newer global models use CPH followed by four digits. Chinese-market units use other prefixes. The letters often hint at the region.
Is a OnePlus locked to a carrier?
Most OnePlus phones are sold unlocked. A few models were also sold through US carriers, and a carrier version of one of those can be locked. The unlock page explains how that is checked.
Will a OnePlus from another country work in the US?
Sometimes, but the bands are tied to the region. Check the exact model number on the compatibility page before you buy.
The dialer code works but Settings shows nothing. Why?
The menu path changes between OxygenOS versions. Look under About device for an IMEI row or a SIM status page, or use the code.
How do I clear a OnePlus before selling it?
Remove the Google account first, then reset. A reset alone leaves the phone asking for the old account at set-up.
