UK Landline Number Validation

Verify phone numbers fast

Our service is a fast and efficient method to validate which UK landline numbers are live. By using the telephone network in real-time, we can tell if a number is available to dial, without making it ring!



In an effort to avoid revealing their identity, some customers will try to give invalid telephone number details. Our telephone verification service means you can immediately identify these and request the real telephone number.

Our solution works by integrating in real-time with the telephone network, using our own custom hardware and software configuration. We are using the actual telephone network and not a simple database so you get accurate, reliable results. Most validation results are returned in around two seconds.

Our phone validation suite of services also includes:
