GSMA Blacklist Check: Is This iPhone IMEI Blocked?
A GSMA blacklist check looks up one IMEI in the registry carriers use for lost, stolen, or unpaid phones.
A GSMA blacklist check asks whether carriers have reported this IMEI as lost, stolen, or unpaid. The GSMA Device Registry is the list operators share. A blacklist check is not an iCloud check, and it is not a SIM-lock check. People mix the three up because any one of them can ruin a used iPhone purchase.
How to read a GSMA blacklist result
- Clean, or not blacklisted, means no operator report was found for that IMEI.
- Blacklisted or blocked means at least one carrier reported it. Networks that use the list can refuse service.
- Removed, or previously blacklisted, means it was listed and later cleared. Ask why. A found phone can be cleared. So can a phone that was billed and then paid.
The report should also name a brand or model from the type allocation code. If that model is not the phone in your hand, the IMEI may not belong to the device being sold.
What a clean blacklist does not clear
Not every theft is reported to a carrier. An iPhone can be clean on a GSMA blacklist check and still have Find My on. It can also be carrier locked, enrolled in MDM, or out of warranty. Run those as their own checks. Do not treat one clean line as a full inspection.
Use the IMEI from Settings or *#06#. Compare it with the SIM tray and the box before you pay. If the seller will not let you read About on the phone, walk away. The blacklist result is only as good as the number you typed.
