| Please note that this table is still under construction. As a result, you cannot assume that I do not have data on those exchanges that are not listed. Instead, what you can more likely assume is that I just have not had time to enter the data yet. |
| Also, there are going to be a lot of dead links at the present time. This is because when I add data for a particular exchange to one table, I do not necessarily add the same exchange's data to all the other relevant tables. So please excuse these problems. |
| I do, however, want feedback on whether you like the format of this site and any suggestions you have for improving it. Please e-mail comments to me on those points. |
Unlike most cities, in Atlanta the transition from their traditional dialing pattern (in Atlanta, the first two letters of an exchange name followed by a four-digit number designating the individual line) to the standard United States pattern (two letters and five digits, the first of which was considered a part of the exchange) was stretched over a bit longer than a year. On August 21, 1955, some exchanges were converted to the standard pattern. However, until November 18, 1956, Atlanta constituted a mixed-pattern city, and both 2L-4N and 2L-5N numbers were the rule, depending on the exchange. 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.
This table gives the exchanges in use in Atlanta after this change of pattern in the mid-1950s. Exchanges are listed in the order of the alphabetical sequence of their names, and within those, by the final digits of the exchanges. For the exchanges prior to the mid-1950s, please see the section of this website devoted to pre-1955 Atlanta exchanges.
The column headed "Previously" gives the previous exchange name, when the
exchange was converted from the earlier 2L-4N pattern. Links are provided to
both the alphabetical and numeric lists of the "early dial" pages. If the
exchange was created anew, the word "New" will be found. The date of conversion
(if converted from 2L-4N) or creation (if new) is also given.

NOTE 1: WAlnut 0001 to 2499 became JAckson 1-xxxx; all others became JAckson 2-xxxx.
NOTE 2: In 1956, Clarkston, Smyrna, and Chamblee (which previously were 4-digit numbers dialed with a code from Atlanta) were added to the named-exchange area. The exchange names HIckory 3 (for Clarkston), HEmlock 5 (for Smyrna), and GLendale 7 (for Chamblee) were established at this time.
