SS7 Point Code Administration
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.
What are Point Codes
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.
iconectiv is responsible for the administration and assignment of SS7 point codes in the United States and other North American Numbering Plan (NANP) countries. For international point codes, contact the Federal Communications Commission (FCC) at 202-418-2214.
