For over 7 years, 200 Networks has augmented Block Assignment Scrubbing with Portability Identification. This is the identification of phone numbers that have been ported or changed by the consumer from a wire-line (land phone) to a wireless (cell phone). In other words, this allows for proper identification of phone numbers that were originally landlines but have recently been ported to be a cell phone.
200 Networks updates our databases of Intermodal Ported Telephone Numbers on a daily basis.
