SCOTSBLUFF prefixes in area code 308

NANPA records 17 assigned NXX blocks to rate center SCOTSBLUFF in area code 308, 3.7% of the 465 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 UNITED TEL CO OF THE WEST DBA CENTURYLINK - NE (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NE (4), ALLO COMMUNICATIONS LLC (3). The earliest assignment on record here is 2002-05-23 and the most recent 2025-09-03. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
