Verification of Spanish numbers with HLR Lookup (without SMS)
Unlike OTP-based solutions via SMS or automatic calls, the HLR Lookup system for Spain allows you to verify mobile numbers by directly consulting the operator’s network, without sending any message to the user.

Invalid or unassigned number detection

PhonesFrequently Asked Questions

The telephone verification service works in real time. On average it takes 1-2 seconds to validate a phone number. The validation of the files depends on the number of records they contain.
How Does the Phone Number Validation Process Work?
We use the telephone network itself to perform the verification process. For mobile numbers we can offer 100% reliability for landline numbers we can also perform a verification but the reliability will depend on the operator managing the number and the country.
