WEATHERFD prefixes in area code 817

NANPA records 21 assigned NXX blocks to rate center WEATHERFD in area code 817, 2.7% of the 781 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 SOUTHWESTERN BELL (7), NEW CINGULAR WIRELESS PCS, LLC - IL (5), LEVEL 3 COMMUNICATIONS, LLC - TX (2). The earliest assignment on record here is 2002-03-28 and the most recent 2022-08-09. 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 codes 580, 682 – overlay codes cover the same geography, so a rate center is served by all of them.
