New Orleans telephone exchanges after the late 1950s



Unlike most cities, in New Orleans the transition from their traditional dialing pattern (in New Orleans, 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 half decade. In 1955, some exchanges were converted to the standard pattern. However, until 1960, New Orleans constituted a mixed-pattern city, and both 2L-4N and 2L-5N numbers were the rule, depending on the exchange.

The tables that this page leads to give the exchanges in use in New Orleans after the late 1950s, when the format of telephone numbers changed from two letters and four digits (two-letter exchange names) to two letters and five digits (two-letter-one-digit exchange names). For the exchanges prior to the late 1950s, please see the section of this website devoted to pre-late 1950s New Orleans exchanges.

This section is organized in the same way as is each geographical section of this site: by exchange. There are three tables, which can be described as alphabetical, numeric, and alphabetical/numeric:



Alphabetic table of exchange names
Numeric table of exchange names
Alphabetic/Numeric table of exchange names
