Real time HLR lookup

Verifies the provided mobile phone number against the definitive source for telephony data used by network providers when routing phone calls.

Validate and standardise

Once the verification is complete, the API returns the input phone number in a standarised format for entry into your customer database, keeping your data clean and free from dead and misformatted numbers.

No confirmation texts

Your customers aren't left waiting for a confirmation code to arrive via text - we validate the number without calling or sending an SMS.

Active checks

Validation confirms not only whether or not the phone number is valid, but if the device it is associated with has been switched on recently.

Know your customer

The HLR lookup process will also confirm what network the number is on, and which country it is based in, allowing you to understand your customer base.
