Call sign - Amateur radio

Amateur radio call signs are in the international series and normally consist of a one- or two-character prefix, a number (which sometimes corresponds to a geographic area within the country), and a 1, 2, or 3 character suffix. The number following the prefix is normally a single number (0 to 9). Some prefixes, such as Djibouti's (J2), consist of a letter followed by a number. Hence, in the hypothetical Djibouti call sign, J29DBA, the prefix is J2, the number is 9, and the suffix is DBA. Others may start with a number followed by a letter, for example, Jamaican call signs begin with 6Y.

The numbers are sometimes assigned geographically. In the Italian call sign, IK1TZO, IK is the prefix, the number component is 1 and corresponds to the Piedmont region, and TZO is the suffix. Another example is WB3EBO. WB is the prefix, the number 3 most often indicates that the station is located in Delaware, Maryland, Pennsylvania, or the District of Columbia, and the suffix is EBO.
