How to check if iPhone IMEI is blacklisted

Hello Russellhussain,

Thanks for connecting with Apple Support Communities.

To ensure that we're on the same page, are you referring to Activation Lock? If so, did you buy an iPhone from someone other than Apple or an Apple Authorized Reseller?

If that's the case, the owner can remove their Apple ID using the following steps: What to do before you sell, give away, or trade in your iPhone or iPad

If the phone has been reported lost or stolen to the carrier, they may block the iMEI from being activated, on a network. In this situation, Apple would not be able to assist you.

The carrier would have to release the iMEI.

If you need further assistance, please provide the community with more details. We'll use this information to provide you with the next best steps to take.

Take care.
