The Wireless Telephone Number Identification Database is a wireless block identifier database used to identify whether a United States or a Canadian telephone number is wireless (cellular) or landline based on current telecom carrier block assignments.
Updated monthly, the database lists all active telephone Area Codes (NPA) and Exchange Prefixes (NXX) at the thousands block level with each block representing 1,000 telephone numbers.
This data provides a first step for those applications seeking U.S. FCC TCPA compliancy. These wireless do not call rules prohibit the initiation of telephone calls using automatic telephone dialing systems or an artificial or prerecorded voice to telephone numbers assigned to a paging service, cellular telephone service, specialized mobile radio service, or other radio common carrier service, or any service for which the called party is charged for the call.
While this database can correctly identify approximately 97% of all telephone numbers as either landline or wireless, both the wireless block identifier database and the Neustar Intermodal Ported Telephone Number database which contains United States nationwide ported telephone numbers that have been moved from landline to wireless and wireless to landline are required for those applications seeking 100% compliance with United States wireless do not call rules.
