FAQ • What is HLR and what are HLR queries used for?

HLR (Home Location Register) is a centralized database that contains detailed information about each subscriber of a given GSM network operator.

With the help of HLR queries, you can check the status of mobile numbers and clean the databases of outdated numbers. The number verification service keeps the request confidential and does not disturb the subscriber.

This service is available both in your personal account and via the API. The cost can be found on the pricing page.
