ALAMOGORDO prefixes in area code 575

NANPA records 31 assigned NXX blocks to rate center ALAMOGORDO in area code 575, 6.0% of the 521 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. 11 holders hold those blocks, the largest being QWEST CORPORATION (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NM (5), T-MOBILE USA, INC. (5). The earliest assignment on record here is 2004-01-09 and the most recent 2025-09-05. 24 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
