HUNTITNBCH prefixes in area code 657
NANPA records 141 assigned NXX blocks to rate center HUNTITNBCH in area code 657, 20.1% of the 703 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. 12 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (105), T-MOBILE USA, INC. (9), FRACTEL, LLC (6). The earliest assignment on record here is 2010-04-14 and the most recent 2026-10-09. 141 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 714 – overlay codes cover the same geography, so a rate center is served by all of them.
