HUNTSVILLE prefixes in area code 256
NANPA records 158 assigned NXX blocks to rate center HUNTSVILLE in area code 256, 20.1% 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. 35 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (46), NEW CINGULAR WIRELESS PCS, LLC - GA (17), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AL (15). The earliest assignment on record here is 2001-04-11 and the most recent 2023-05-23. 83 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 423, 479, 660, 936 – overlay codes cover the same geography, so a rate center is served by all of them.
