Many Xiaomi buyers get caught out purchasing devices sold as "global versions" from unofficial shops or as second-hand units, only to find out later they're Chinese (CN) variants that have been tampered with.
If you're about to make a purchase and want to be sure before handing over money, here's a practical three-step check you can run on the device beforehand to confirm it isn't a Chinese Xiaomi.
Step 1: ROM Version Code (Preliminary Check)
Check the ROM version string on the device. The two letters before the last two characters indicate the region:
OS3.0.10.0.WOJCNXM — China (Destined for: China)
OS3.0.10.0.WOJMIXM — Global (Destined for: Worldwide)
OS3.0.10.0.WOJTWXM — Taiwan (Destined for: Taiwan)
OS3.0.10.0.WOJRUXM — Russia (Destined for: Russia)
OS3.0.10.0.WOJIDXM — Indonesia (Destined for: Indonesia)
OS3.0.10.0.WOJTRXM — Turkey (Destined for: Turkey)
OS3.0.10.0.WOJEUXM — Europe (Destined for: Europe)
OS3.0.10.0.WOJINXM — India (Destined for: India)
If those two letters are not CN, the device is not a Chinese unit.
This check alone won't catch Chinese devices that have had a Global ROM installed.
Step 2: IMEI Verification
Dial *#06# to retrieve your IMEI numbers, then go to:
https://www.mi.com/global/verify#/en/tab/imei
Try the first IMEI, the second IMEI, and the serial number (S/N). If the device isn't a Chinese unit, all three should return:
This is a
<device name><colour><RAM/ROM>Congratulations! You can be assured the phone you have purchased is the official international version.
This check won't catch Chinese devices whose IMEI has been replaced with one registered on Xiaomi's servers as international.
Step 3: CPU ID Verification
Dial *#*#6484#*#* → Software version → CPU ID
Then go to: https://offici5l.github.io/MiCheck
Enter the CPU ID and the device codename. If the device isn't a Chinese unit, you'll get:
Congratulations! You can be assured the phone you have purchased is the official international version.
