Do Wireless Carriers have to port numbers?

The wireless industry was given an extension until November 2002 by the FCC to implement full Number Portability in the 100 largest MSAs. However, wireless providers are required to be able to complete calls to ported numbers in the 100 largest MSAs as of December 31, 1998. If the wireless carrier sends a call to the terminating carrier; in other words, the wireless carrier is the N-1 carrier, then the wireless carrier is responsible for doing the LNP database query. They can either perform the query themselves or default route the call to the original carrier (the NPA-NXX owner) to perform the query. Charges will be incurred if default routing is used. Issues pertaining to full Number Portability for wireless carriers are being addressed by the Wireless Number Portability Sub Committee (WNPSC) of the LNPA WG.
