OnePlus

OnePlus is a Chinese smartphone manufacturer founded in 2013, now a sub-brand of OPPO under the BBK Electronics group. The OnePlus lineup spans the flagship Numbered series (OnePlus 12, 13), the affordable Nord series, and OxygenOS — OnePlus's Android skin — which is shared closely with OPPO's ColorOS in recent versions. Every OnePlus phone carries a 15-digit IMEI registered with the GSMA, and an IMEI check identifies the exact regional variant (Indian, North American, European, or Chinese) which matters for warranty and network compatibility.

Find your OnePlus IMEI by dialling *#06# on the keypad, opening Settings → About device → Status information → IMEI, or checking the original retail box. The SIM tray on most OnePlus phones is also laser-etched with the IMEI. Dual-SIM OnePlus models — most international SKUs — have two IMEIs, one per SIM slot; both are valid identifiers for the same device.

OnePlus regional variants can look identical but ship with different network bands, modem firmware, and OxygenOS builds. A North American OnePlus 12 will not support every Indian band, and a Chinese OnePlus model ships with ColorOS instead of OxygenOS in some recent releases. Run the IMEI through our free IMEI checker to identify the exact variant before buying internationally or unlocking.

For warranty status on a OnePlus device, our IMEI check returns the model identifier, then you can verify warranty on OnePlus's regional support portal — OnePlus provides a one-year limited warranty in most markets, two years in the EU. To check whether a used OnePlus has been reported lost or stolen, run the IMEI through our lost & stolen database; OnePlus devices are common targets in India and Southeast Asia where they have particularly strong market share.
