YOAKUM prefixes in area code 361

NANPA records 8 assigned NXX blocks to rate center YOAKUM in area code 361, 1.5% of the 538 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. 5 holders hold those blocks, the largest being SOUTHWESTERN BELL (4), TELNYX LLC (1), ONVOY, LLC - TX (1). The earliest assignment on record here is 2002-10-24 and the most recent 2021-05-07. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
