They were first called Star Services, then became Network Services and the latest name is Select Services. BT seem incapable of keeping their name the same for any length of time, but the functions change little. That's if you know exactly what the functions are, as BT are also very tight lipped on what some of them do.

The list is in numerical order of function number. Please click on the function number to get further details of the service and how to use the commands.

I've had great difficulty finding a COMPLETE list anywhere, so here are the ones I've found out so far from various official and unofficial sources. Please use the mail route at the bottom of the page if you know any more that I can add.

Whether some or all of these codes will work from your BT line will depend on which services you rent. If you try any of them and get the nice lady saying "Sorry, the service requested is not available", then you'll need to ring BT and shell out some money to get them working.
