MCCOOK prefixes in area code 308

NANPA records 8 assigned NXX blocks to rate center MCCOOK in area code 308, 1.7% 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. 7 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NE (2), LEVEL 3 COMMUNICATIONS, LLC - NE (1), PINPOINT COMMUNICATIONS, INC. - NE (1). The earliest assignment on record here is 2002-01-23 and the most recent 2023-01-03. 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 code 956 – overlay codes cover the same geography, so a rate center is served by all of them.
