CULLMAN prefixes in area code 256

NANPA records 36 assigned NXX blocks to rate center CULLMAN in area code 256, 4.6% of the 786 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. 12 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (13), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (8), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AL (4). The earliest assignment on record here is 2001-02-27 and the most recent 2022-09-13. 30 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 938 – overlay codes cover the same geography, so a rate center is served by all of them.
