Phone Codes Guide
Star Codes
Vertical Calling Codes Guide

by Vaughn Aubuchon

Here is a list of digital telephone calling feature codes for controlling your phone. These "Star Codes" are used by AT&T, and other telephone companies.

These codes are called VSC - Vertical Service Codes. I list them here because 1) I could not get the AT&T Guide instructions included with my telephone bill to work, and 2) because AT&T does not publish the 3-digit codes online.

DISCLAIMER
The author is in no way affiliated with AT&T.
Although the author has tried to be as accurate as possible, errors are possible.
I could not find a telephone star code guide like the above. So, I made this one, to summarize all the common Vertical Service Codes. I hope that it helps you. Especially, since AT&T does NOT provide the codes online.
