Our Phone Validation service captures accurate, callable contact information in real-time. Incorporating three core products, our phone number checker can be quickly and easily integrated into your system.

UK Landline Number Validation

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 the cost of a phonecall!

Mobile Number Validation

Our real-time Mobile Number Validation service is a fast and efficient method to validate which mobile numbers are currently live. We can also tell you about the mobile network, number type and location.

International Telephone Validation

By using our international Telephone Number Validation service, you can immediately identify bogus numbers and request the legitimate number. Our international coverage is constantly growing.

Phone Validation

How does it work?

A phone call is one of the most effective tools for doing business, but it only takes a single mistyped digit to turn a prospective customer into a lost opportunity.

Our Phone Validation service goes beyond checking the length of the number; it verifies whether it’s callable, screens it against the TPS register, and identifies information such as its type, location and network.

We don’t cache results; we check each number in real time, so you can be confident all information is 100% accurate and up-to-date.

There are so many benefits to using our Phone Validation Service

Real time TPS screening

By checking if a number is registered with the TPS, you protect your company’s reputation, save time by reaching out to the right prospects and reduce the risk of legal fines.

Increased conversions

Without validation at point of entry, you risk capturing mistyped phone data, jeopardising any future communication and therefore losing a prospective customer from the offset.

Save time

In business, time is money. By capturing accurate phone numbers first time, you’ll cut time spent calling invalid numbers and re-capturing correct data, while reducing missed opportunities.

Customer Satisfaction

Telecommunications is still the most popular method of communication, by validating numbers at point of entry, you deliver a smooth experience for your customers and your staff.

Multiple platforms

Whether filled in by customers or staff, small mistakes can cost big business. With our phone validation service on your website, app, and CRM, you’re covered across all systems.


Verifying phone numbers has never been easier. With a simple, seamlessly integrated API, you get full power to validate at point of capture, pre-send or as a batch cleanse.
