LAS VEGAS prefixes in area code 505
NANPA records 15 assigned NXX blocks to rate center LAS VEGAS in area code 505, 2.2% of the 685 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. 8 holders hold those blocks, the largest being ONVOY, LLC - NM (4), QWEST CORPORATION (3), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2002-03-20 and the most recent 2024-03-21. 11 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 702, 725 – overlay codes cover the same geography, so a rate center is served by all of them.
