VISTA prefixes in area code 442

NANPA records 12 assigned NXX blocks to rate center VISTA in area code 442, 3.4% of the 356 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. 7 holders hold those blocks, the largest being T-MOBILE USA, INC. (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (3), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2013-03-28 and the most recent 2024-11-12. 12 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 code 760 – overlay codes cover the same geography, so a rate center is served by all of them.
