ROSWELL prefixes in area code 575

NANPA records 28 assigned NXX blocks to rate center ROSWELL in area code 575, 5.4% 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. 10 holders hold those blocks, the largest being QWEST CORPORATION (7), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NM (5), NEW CINGULAR WIRELESS PCS, LLC (5). The earliest assignment on record here is 2001-07-17 and the most recent 2023-09-06. 18 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
