| 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. |
The following table lists exchange names used in New York after December 1930, when the format of telephone numbers changed from three letters and four digits (three-letter exchange names) to two letters and five digits (two-letter-one-digit exchange names). This is one of a series of tables covering the post-1930 period, and if you have not already read the information on the master page of the set, you are advised to do so. Exchanges are listed in the order of the alphabetical sequence of the first two letters of their names, followed by the final digits of the exchanges. Thus all "LOngacre" exchanges and all "LOrraine" exchanges are listed together in numeric order, regardless of which name applied. (For a table with the exchanges ordered by the complete names, click here. For a table with the exchanges ordered numerically by the three-digit equivalent of the exchange name, 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 exchange name in the table. In particular, that table shows the correspondence between these post-1930 exchanges that used two letters and 1 digit in the exchange part (two letters and five digits for the whole telephone number) and the pre-1930 three-letter exchanges. In addition there is a table ordered by the three-digit numeric values which can be reached by clicking on the three-digit numeric equivalent shown in the listing.
