This numbering resource is administered by iconectiv for Canada, the United States, and other North American Numbering Plan (NANP) countries.

GTT Point Code/SS7 Description

SS7 point codes are unique addresses that identify individual network elements for a Signaling Point used in Message Transfer Part (MTP) to identify the destination of a message signal unit (MSU). The national administration and assignment of point codes for the United States and other North American Numbering Plan (NANP) countries are maintained in one database by iconectiv on behalf of ATIS-PTSC.

Point codes are 24-bit binary codes that are needed for all signaling points using the Signaling System 7 (SS7), also known as Common Channel Signaling (CSS) network. They identify network nodes so that the SS7 network can route calls properly. Point codes consist of 9 digits. The first three digits represent the network, the second three digits represent the cluster, and the third three digits represent the member. Large networks start at network 254 and are decrementing. Small networks are assigned from network code 002 and point code blocks are assigned from network code 005.
