DEMING prefixes in area code 575

NANPA records 11 assigned NXX blocks to rate center DEMING in area code 575, 2.1% 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. 6 holders hold those blocks, the largest being QWEST CORPORATION (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NM (3), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2002-03-20 and the most recent 2022-03-03. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
