NOGALES prefixes in area code 520
NANPA records 32 assigned NXX blocks to rate center NOGALES in area code 520, 4.6% 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. 13 holders hold those blocks, the largest being QWEST CORPORATION (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AZ (6), T-MOBILE USA, INC. (4). The earliest assignment on record here is 2001-05-15 and the most recent 2026-10-30. 27 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
