Live Number Testing Web Service API
This service can be used in conjunction with our telephone
validation and mobile validation
services to provide complete coverage of all UK telephone numbers. When selected, the Telephone
Validation Service can use the Live Number Testing Service or Mobile Validation Service to
provide the most accurate results without you having to select which service to use for each individual number.
The service works by integrating in real-time with the telephone network, using our own custom hardware and software configuration.
Because we are using the actual telephone network and not a simple database, you get absolutely reliable results. Most validation
results are returned in around two seconds.
Note that this service is different to telephone "pinging", as our custom system does not actually place a real call. The number
being validated will not ring
or be unavailable for other incoming calls, and your customer will be entirely unaware
that their number has been validated.
