What is an IMEI number?

IMEI stands for International Mobile Equipment Identity. Similar to an ESN, a phone has a different IMEI, just like every human has a different fingerprint. Phone carriers use your IMEI to monitor whether your account has any past due bills or has been reported as lost or stolen. The IMEI number is used for GSM phones and is similar to how MEID numbers are used for CDMA.

Before buying or selling a used phone you should always make sure the IMEI number is “clean”. To check if the number is clean you can call your phone carrier from the list below. Please call from a number other than the phone you are requesting information on.

What is a Bad IMEI?

Your carrier may tell you your phone has a “bad” IMEI. This means that it can not
be activated with them. If the phone is yours, you either likely have an overdue
balance on your account or had previously reported it lost/stolen. In speaking with
your carrier you should be able to resolve this. If you received a phone with a bad IMEI,
you will need to contact the previous owner and have them try to resolve it.
