USA SPIDs by Telco
Here is a list of known working SPIDs (Service Profile IDs) by telephone company, compiled from our
direct experience helping clients with ISDN installations. Your SPIDs may be different, of course.
e SPID is distinct from your telephone number, and does not necessarily contain your area code or
telephone number, although this is generally the case. Incorrect SPIDs will be indicated by the line status
indication Wait on the Nx12 ISDN status screen. Often the Telco will leave the last “00” or “01” off the
end of your SPID when giving it to you. For the latest list check Telos Systems’ web page.
A standardized SPID format for national ISDN of XXXYYYZZZZ0101 was phased in during 1996 and
is used by most of the Telcos for new lines.
In the list below, XXX=Area code; YYY=exchange; ZZZZ=phone number.
