HUNTSVILLE prefixes in area code 936

NANPA records 29 assigned NXX blocks to rate center HUNTSVILLE in area code 936, 6.9% of the 422 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 SOUTHWESTERN BELL (11), NEW CINGULAR WIRELESS PCS, LLC - IL (3), LEVEL 3 COMMUNICATIONS, LLC - TX (3). The earliest assignment on record here is 2001-01-16 and the most recent 2024-10-29. 22 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 256, 423, 479, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
