BRIAN HEAD prefixes in area code 435

NANPA records 4 assigned NXX blocks to rate center BRIAN HEAD in area code 435, 0.8% of the 501 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 SOUTH CENTRAL COMM -TELCOM SERVICES, LLC UT (1), TON80 COMMUNICATIONS, LLC (1), QWEST CORPORATION (1). The earliest assignment on record here is 2014-02-06 and the most recent 2021-04-12. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
