BISBEE prefixes in area code 520

NANPA records 9 assigned NXX blocks to rate center BISBEE in area code 520, 1.3% of the 699 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 5 holders hold those blocks, the largest being ONVOY, LLC - AZ (4), QWEST CORPORATION (2), PEERLESS NETWORK OF ARIZONA, LLC - AZ (1). The earliest assignment on record here is 2012-05-08 and the most recent 2023-06-22. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 701 – overlay codes cover the same geography, so a rate center is served by all of them.
