Verizon Wireless and Cingular Sign Number Porting Agreement

BEDMINSTER, NJ and ATLANTA — Verizon Wireless and Cingular Wireless today announced that they have signed an agreement detailing how they will port customers' phone numbers between them once the first phase of local number portability takes effect on November 24, 2003.

The agreements address operational details, such as the troubleshooting procedures and communications protocols the carriers will follow during the porting process. While the Federal Communications Commission does not require carriers to sign such agreements in order to port numbers, Verizon Wireless and Cingular agreed that formal porting agreements would allow them to cooperate as efficiently as possible during the LNP process, which is in the best interest of their customers.
