LAKEHUGHES prefixes in area code 661

NANPA records 7 assigned NXX blocks to rate center LAKEHUGHES in area code 661, 1.0% of the 674 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. 6 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - CA (2), IP HORIZON LLC (1), UTILITY TELECOM GROUP, LLC - CA (1). The earliest assignment on record here is 2022-02-18 and the most recent 2022-02-18. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
