Ham Radio Call Sign Systems

(Latest information taken directly from the FCC as of January, 2011)
A unique call sign is assigned to each amateur station during the processing of its license. Each new sequentially assigned call sign is sequentially selected from the alphabetized regional-group list for the licensee's operator class and mailing address. The mailing address must be one where the licensee can receive mail delivery by the United States Postal Service.

The station is reassigned its same call sign upon
renewal or modification of its license, unless the licensee applies for a change to a new sequentially assigned or vanity call sign on FCC Form 605.
Each call sign has a one letter prefix (K, N, W) or a two letter prefix (AA-AL, KA-KZ, NA-NZ, WA-WZ) and a one, two, or three letter suffix separated by a numeral (0-9) indicating the geographic region. Certain combinations of letters are not used. When the call signs in any regional-group list are exhausted, the selection is made from the next lower group. The groups are:
