959 numbers by decoder Here are some scans of 959 numbers I did. Of course, 104t is from my local area. Depending on where you are, you will get something different. So far, I have not found anything special past 6919. After that I get my local cannot be completed as dialed message, which is usually also on 6901. There are also some goodies in 959-1xx0. Mostly milliwtatts and such. In some cases, you can be charged for calling a milliwatt, since they supervise. Error messages do not supervise so all of these calls are free. keep in mind that you must use an AT&T controlled PICC, and that 959 numbers do not work in every area code. I also have not figured out yet how to reach 959 numbers in your own area code. The key number in this list is 212-959-6906.
