LARAMIE prefixes in area code 307
NANPA records 18 assigned NXX blocks to rate center LARAMIE in area code 307, 3.6% 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. 8 holders hold those blocks, the largest being QWEST CORPORATION (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WY (3), LEVEL 3 COMMUNICATIONS, LLC - WY (2). The earliest assignment on record here is 2002-05-16 and the most recent 2025-01-09. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
