The International signalling point codes (ISPCs) and signalling area/network codes (SANCs) that facilitate all telephone calls are now available to members in an online database.

Previously up-to-date information was only available to subscribers to ITU-T’s freely available Operational Bulletin.

The database provides easier access to the information and also presents it in a machine-readable form.

An ISPC is used in association with signaling system seven (SS7), and acts in a similar way to an IP address in an IP network. It is a unique address for a node to identify the destination of a message.

The action was taken following a request by ITU-T Study Group 11.
