LAKE prefixes in area code 307

NANPA records 4 assigned NXX blocks to rate center LAKE in area code 307, 0.8% 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. 4 holders hold those blocks, the largest being AIRUS, INC. - WY (1), QWEST CORPORATION (1), ONVOY, LLC - WY (1). The earliest assignment on record here is 2018-12-06 and the most recent 2026-03-31. 4 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 601, 769 – overlay codes cover the same geography, so a rate center is served by all of them.
