As outlined in PL 406, and continued observance of PCS guidelines governing 5YY NXX Code Assignment, NANPA has posted PL 411 as an industry notification regarding current supply. This notification is required six months before the exhaust of the PCS 5YY resource (which are presently the 500 and 533 NPAs); and, to inform that once 100% of the remaining 500/533 codes are assigned, the next PCS 5YY code will be available.
PL 411, utilizing current information regarding the available supply of 5YY NXXs, serves to notify of the revised exhaust date for 5YY resources, which is now expected to be fourth quarter of 2010. NANPA will continue to keep the industry updated regarding any modifications to this projection.
"The 5YY NPA resource is a non-geographic Service Access Code (SAC) used for personal communications services. As stated in the Personal Communications Services (PCS) 5YY NXX Code Assignment Guidelines, personal communication service is a set of capabilities that allows some combination of personal mobility, terminal mobility, and service profile management. It enables each personal communication service user to participate in a user-defined set of subscribed services, and to initiate and/or receive calls on the basis of some combination of a personal number, terminal number, and a service profile across multiple networks at any terminal, fixed or mobile, irrespective of geographic location."
