phone number verification solution

With CM's number validation & number lookup API, you can validate any phone number. It will tell you the formatting options and number type, as well as the most likely carrier.

Also, you can generate additional information for phone numbers in your database. This contains information like formatting options, the actual operator, if the number is roaming and even if the number is active on the network.

You can verify one phone number at a time or validate multiple numbers at once with the same ease.
