The Real Phone Validation API provides tools that ping the phone company switches and analyzes the data returned to determine the status of a number. Real Phone Validation also gives the standard results of Connected, Disconnected, Restricted, Busy, Invalid Number - not a scoring system to be interpreted. In addition to Connected / Disconnected, Real Phone Validation also provides Phone Type (mobile/ landline), Caller ID and Carrier. It is available for US and Canadian phone number validation.
The following is a list of historical changes that were made to this asset. Typically, once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change. As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset, we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb. If you spot an error in our data and believe that a record needs to be updated in some way, the ProgrammableWeb team would very much like to hear from you at email@example.com
