Telephone Validation Web Service API
|
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).
To make it even easier to use if you're an ASP.NET developer, you can
use our ready-made
ASP.NET validator controls to use this service as
a standard ASP.NET validator.
