Is it possible to validate IMEI Number?

Question

For a mobile shop application, I need to validate an IMEI number. I know how to validate based on input length, but is their any other mechanism for validating the input number?

Answer 1

I don't believe there are any built-in ways to authenticate an IMEI number. You would need to verify against a third party database (googling suggests there are a number of such services, but presumably they also get their information from more centralised sources).
