An interesting case is the rate center of Britton, Oklahoma. The tariff location of this rate center is the one-time location of a step CDO in the back of a long-gone barber shop in what was once the independent town of Britton. That municipality was dissolved and incorporated into the limits of Oklahoma City sometime around 1950.
The boundaries of the rate center included, and still include, a considerable portion of Oklahoma City as far south as NW 47th Street (the Britton CDO is at about NW 92nd Street) and extend far to the north, east and west, including not only the original town of Britton, the upscale residential city of Nichols Hills, another residential city by the name of The Village (in which I live) and the southern part of Edmond, Oklahoma, a continually growing suburb noted for its hospitality of many PGA golfers, among other things. It includes the 842 wire center building to the south, the 478 wire center to the northeast toward Edmond, and the 751 wire center to the north, which includes a major shopping mall in Oklahoma City. All three of those have multiple central office codes. (The 478 office also hosts the offices and printing plant of The Daily Oklahoman, the largest newspaper by circulation in Oklahoma.) (The original Britton CDO was TRinity-8, and I believe it passed out of existence before the adoption of All Number Calling.)
If your bill shows a call to or from Britton, Oklahoma, which no longer exists, it may be in any of those places. Those wire centers (central offices) are each several miles from one another.
Incidentally, a central office (wire center) can serve customers in more than one rate center, if that's what the engineering economics lead to.
