IMEI Format Check Nepal
Validate a 15-digit IMEI format and checksum, then continue to the official NTA MDMS portal. This tool does not check blacklist, ownership, carrier, iCloud, MDM, or warranty status.
Why check IMEI?
Catch typing errors
The Luhn checksum can detect many invalid or mistyped IMEI numbers.
Prepare for the official check
Copy the validated 15-digit number into the NTA MDMS portal.
Understand the result
Format validation is not proof of registration, ownership, blacklist, carrier, or lock status.
This result validates format only and is not a live GSMA, carrier, manufacturer, blacklist, or lock-status report. Check Nepal registration status through NTA MDMS.
What We Check
15-digit format
Checks the number length and Luhn checksum locally.
TAC reference
May show a non-authoritative model suggestion from a limited local reference.
Official next step
Links to the Nepal Telecommunications Authority MDMS registration check.
How It Works
1
Enter IMEI
Type or paste the 15-digit IMEI from your device settings or original box.
2
Validate Format
The tool checks length and checksum. It does not query a live provider.
3
Open NTA MDMS
Use the official portal to check Nepal registration status.
4
Inspect the phone
Check ownership, account locks, carrier behavior, and physical condition separately.
How to Check IMEI in Nepal
An IMEI check is one part of due diligence when buying a second-hand phone. Use the format check, the official NTA MDMS registration check, proof of ownership, and an in-person account-lock inspection.
1
Find the IMEI
Dial *#06# on the phone you want to buy. The 15-digit IMEI number will appear on screen. Alternatively, check under Settings → General → About (iPhone) or Settings → About Phone (Android). You can also find it printed on the original box.
2
Validate the format here
Enter the IMEI above to check its 15-digit format and Luhn checksum. Passing this check does not prove that the phone is registered, genuine, unlocked, or safe to buy.
3
Check NTA MDMS
Use the Nepal Telecommunications Authority MDMS portal to check the device registration status. Also verify ownership and account locks directly on the phone before purchase.
Why this matters in Nepal: The used phone market on platforms like Hamrobazar has many listings without IMEI disclosure. A checksum result cannot reveal blacklist, carrier-lock, iCloud, MDM, or ownership state. Confirm each of those independently before paying for a used phone.
