All of these codes work from Corpus Cristi, Texas but if you're reading this from another state, you'll notice that some of the codes don't work and there's some that aren't listed here. Sorry, but I just didn't have the time to take airplanes around the U.S. and try out the codes everywhere.
To use a long distance code, dial 10xxx-1-AREA CODE-NUMBER. To speak with an operator, dial 10xxx-0. To identify what a certain code is, dial 10xxx-1-700- 555-4141 and it'll usually tell you what carrier owns it. That 700 number is a free call, by the way. If you want to use your stolen calling card with one of these codes, dial 10xxx-0-AREA CODE-NUMBER and follow the instructions. Some of these people won't let you place a call unless you have an account on their system.
Most of these companies know exactly where you're calling from and what your phone number is but a few can't tell so you can use them as extenders. My favorite to play with is 109870. It's just like 1-800-COLLECT but it's a little less advanced AND it's in Spanish. It really confuses whoever you call.
