This page and its subpages provides a list of all central offices for a particular state or province. No other page I'm aware of provides this in this format. Much of the raw data is from localcallingguide.com and telcodata.us. However compiling the data in this format is/has been a very involved process.

The complexity is similar to the problem you would have if you wanted to compile a list of all of the McDonalds or Starbucks in the state of Illinois. It is very easy get a list of stores within 20 miles of zip code 60402, but to get a list for the whole state, you would need to do queries on strategically selected zip codes until you eventually get every store in the state..

townoak.com/us/ga below for the State of Georgia is the most complete. In addition to landlines it includes central offices for wireless and a 'clec and other' category. Hopefully all states and provinces below will also have that level of detail.

Count = 111

"Originally only 86 area codes of the 152 possible codes were assigned. The most populous areas received the numbers that took the shortest time to dial on rotary telephones.[8] Thus, five largest cities based on 1950 US Census population received some of the shortest codes: New York City was given 212, Chicago 312, Los Angeles 213, Detroit 313, Philadelphia 215; while four areas received the then-maximum number of 21 clicks: South Dakota (605), North Carolina (704), South Carolina (803), and the Maritime Provinces of Canada (902). In the original plan a middle digit of 0 indicated that the area code covered an entire state or province, while area codes with a middle digit of 1 were assigned to jurisdictions that were divided into multiple area codes.[9]"

The above paragraph is the first paragraph in the Numbering system section of the North American Numbering Plan article in wikipedia(I bolded some of the words).

"Most of the thousands of 1ESS and 1AESS offices in the USA were replaced in the 1990s by DMS-100, 5ESS Switch and other digital switches, and since 2010 also by packet switches. As of late 2012, just under 40 1AESSes remain in the North American PSTN. These are located mostly in AT&T's legacy BellSouth and AT&T's legacy Southwestern Bell states, especially in the Atlanta GA metro area, the Saint Louis MO metro area, and in the Dallas/Fort Worth TX metro area, although there are still a few remaining 1AESS switches in other parts of BellSouth's and Southwestern Bell's legacy territory. AT&T does plan on replacement of several more existing 1AESS switches, with new packet switches, during 2013."

The above paragraph is the last paragraph in the 1ESS article in wikipedia(I bolded some of words).
