LA MESA prefixes in area code 575

NANPA records 4 assigned NXX blocks to rate center LA MESA in area code 575, 0.8% 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. 4 holders hold those blocks, the largest being QWEST CORPORATION (1), LEVEL 3 COMMUNICATIONS, LLC - NM (1), PEERLESS NETWORK OF NEW MEXICO, LLC - NM (1). The earliest assignment on record here is 2008-10-20 and the most recent 2022-03-03. 4 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 codes 619, 858 – overlay codes cover the same geography, so a rate center is served by all of them.
