LINGLE prefixes in area code 307

NANPA records 3 assigned NXX blocks to rate center LINGLE in area code 307, 0.6% of the 499 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. 3 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - WY (1), ONVOY, LLC - WY (1), UNITED TEL CO WEST - WY DBA CENTURYLINK WEST - WY (1). The earliest assignment on record here is 2016-11-16 and the most recent 2023-05-24. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
