Atlanta telephone exchanges after the mid-1950s

(numeric listing)

Telephone exchanges in Atlanta, unlike in many other places, were changed over from the 2L-4N format to the standard 2L-5N format over a period of time. The first changes were made in 1955, but they continued for over a year afterward. For detailed chronological data, see the alphabetic listing. This is one of a series of tables covering the post-format-change period, and if you have not already read the information on the master page of the set, you are advised to do so.

The following table lists exchange names used in Atlanta after the changes to two letters and five digits (two-letter-one-digit exchange names). Exchanges are listed in the order of the numeric equivalents of the three-letter prefixes. (For a table with the exchanges ordered alphabetically by exchange name, click here. For a table with the exchanges ordered by the two- letter prefixes and third digits, click here.)

The primary table for this era is the one ordered by exchange name, which contains more information on each exchange than is given here. To see the table entry for any exchange name in that table, click on the middle part of the exchange name in the table. In particular, that table shows the correspondence between these post- mid-1950s exchanges that used two letters and 1 digit in the exchange part (two letters and five digits for the whole telephone number) and the 1923-to-mid-1950s two-letter exchanges. (Clicking on either the first two letters or the office number will bring you to the listing in the table with the exchanges ordered by the two-letter prefixes and third digits, mentioned in the previous paragraph.)
