On September 9, 1956 a new telephone directory became effective, and the EMerson 6 exchange began service. It is not clear whether 2 letter + 5 digit numbers also started on that date (the directory seems to imply that all numbers were changed on that date), and so I will assume that this was the start but will change the header on this page if I find out otherwise.
It should be noted that, while links to the pre-dial and early dial periods are provided, they will not provide any data at present; they are only here for future use.
Since all the exchange names at the beginning of the late dial period began with a letter that corresponds to the digit "3," it would be possible that all the exchanges were changed from 2 letter + 4 digit to 2 letter + 5 digit numbers by prefixing a 3, a system similar to what was done in Portland, Oregon. However, this is simply speculation.
Because the number of exchanges is so small, instead of having three pages, each with a different table, all the tables are put together on this page. In addition the alphabetical order by exchange name would be identical to that by the first two letters plus the office number, so these tables are combined into one.
In the following table, the column listed “Exchange” shows the name and office number of each exchange used in Charlotte during the period when exchanges were dialed as 2 letters and 5 numbers. While the information comes from only two sources, one of those reflects the start of 2 letter + 5 number dialing and one was at the start of all-number calling, so it is likely that any 2 letter + 5 number exchange used in Charlotte was included. (While this would not be true for a larger city, because new exchanges started after the beginning of 2 letter + 5 number calling might have been discontinued before the start of all-number calling, the small number of exchanges in Charlotte suggests that there were no exchanges of that nature.) The entries are ordered strictly alphabetically, so that “EXpress 2” precedes “FRanklin 5” even though the former is dialed as 392 and the latter as 375.
In the column headed “Numeric value” is given the three-digit equivalent of the exchange. Clicking on that number will send you to the corresponding entry in the table in which the exchanges are ordered by those numeric values.
The entries in the column headed “Start of service” are of several kinds:
The entries in the column headed “Subsequently” are of two kinds:
In the “Notes” column, if the phrase “Used in” is found, it means that the exchange was not used in Charlotte proper, but in one of the nearby smaller communities. The absence of that note probably, but not certainly for all exchanges, implies that the exchange was used in Charlotte proper.
