In the 1920s, the first telephone exchanges in Buffalo, New York were converted to dial. Although at that time most exchanges remained manual, that can be considered the beginning of the "early dial" period in Buffalo, New York, in which telephone numbers were set up to accommodate dialing the first two letters of an exchange name followed by a four-digit number designating the individual line. Over the succeeding years, as exchanges were converted to dial, this pattern continued until October 16, 1960, when Buffalo changed from two-letter to two- letter-one-digit exchanges.
This section is organized in the same way as is each geographical section of this site: by exchange. There are two tables, which can be described as alphabetical and numeric:
