Save time and money by ensuring your customersâ€™ phone numbers are correct with StrikeIronâ€™s Phone Number Validation solution. You can easily integrate this cloud based solution into any website, web form, or other business application to improve customer contactability by 90% or more.
This solution verifies the NPA and the NXX (area code and prefix) of all North American Numbering Plan (NANP) phone numbers in the US and Canada. In addition this solution will return each zip code where this NPA/NXX combination exists. It will also give you the number of phone numbers in each of these ZIP codes. We update our data at least every 30 days to ensure we provide the most accurate solution.
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 firstname.lastname@example.org
