The beginning of the list of call sign ranges is:* AAA–ALZ United States of America Call Sign Prefix State ------------------------------------------------------------------------------------------- W0 Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, South Dakota W1 Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont W2 New Jersey, New York W3 Delaware, D.C., Maryland, Pennsylvania W4 Alabama, Florida, Georgia, Kentucky, North Carolina, South Carolina, Tennessee, Virginia W5 Arkansas, Louisiana, Mississippi, New Mexico, Oklahoma, Texas W6 California W7 Arizona, Idaho, Montana, Nevada, Oregon, Washington, Utah, Wyoming W8 Michigan, Ohio, West Virginia W9 Illinois, Indiana, Wisconsin AL0-7, KL0-7, NL0-7, WL0-7 Alaska AH6-7, KH6-7, NH6-7, WH6-7 Hawaii While the prefix uniquely identifies a country the suffix is unique for the individual. In Canada a call sign such as VE3ABC has VE3 (Ontario) as the prefix and ABC as the suffix. In the U.S the call sign N2MG has a prefix of N2 and suffix of MG. U.S. hams may also have a two letter prefix thus AB2Z is a valid call. Suffixes may also be less than three letters so you have call signs such as VE7AB in British Columbia and KH6Y in Hawaii. * [http://www.qrz.com/hamtest/ Practice Amateur Radio Exams]
