Service Profile Identifiers

Service Profile Identifiers (SPIDs) are only allocated by service providers in the United States and Canada. Service providers in these markets create a service profile based on which ISDN features you require, then assign you a unique Service Profile Identifier (SPID) which allows you to use these particular features.
