Stop time-wasters and avoid typing errors by checking telephone numbers in real time as they are entered against the full, official list of valid telephone number ranges.
In an effort to avoid revealing their identity, some customers will try to give invalid telephone number details. By using the Integr8 Telephone Number Validation service, you can immediately identify these and request the real telephone number.
Did you know, of the over 170,000 telephone number ranges in the UK, only 62,000 (36%) actually contain callable telephone numbers?
Most traditional methods of validating telephone numbers only check that it contains an expected number of digits, and do not check whether they constitute a callable telephone number. The Data8 service goes far beyond this, checking whether the number is the correct length based on the exchange (some exchanges for smaller areas only have 5 digit local numbers, while most have 6) and falls into a valid range (most exchanges have only allocated certain ranges of the possible numbers, for example the 01234 exchange does not allow any numbers starting with 1, except those starting 15).
This service can be used in conjunction with our mobile validation and live number testing services to provide even more accurate results using the telephone networks themselves. When selected, the Telephone Validation Service can use the Telephone Line Validation Service or Mobile Validation Service to provide the most accurate results without you having to select which service to use for each individual number.
