IMEI Service Details

Our Blacklist check is our mobile phone diagnostics device check that provides instant information from our extensive data ecosystem to help you avoid buying stolen mobile phones.

Combining live data from four key sources, including; Insurance Companies, Law Enforcement Agencies, Recyclers and Mobile Networks, this check is an instant due-diligence solution that provides assurance that the phones you purchase have been comprehensively checked and authenticated to be suitable for re-use and re-sale.

We check device IMEI numbers live against a variety of independent datasets, including the GSMA Global Blacklist Registry, to provide the most up-to-date information possible on the history of a mobile phone, including whether or not it is network blocked, has been reported lost or stolen, is under finance, or has been subject to an insurance claim.

Protect yourself before you buy, providing security and peace-of-mind that your purchasing decisions are free from mobile device fraud.
