GADSDEN prefixes in area code 256

NANPA records 37 assigned NXX blocks to rate center GADSDEN in area code 256, 4.7% 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 BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (11), NEW CINGULAR WIRELESS PCS, LLC - GA (7), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AL (4). The earliest assignment on record here is 2001-04-17 and the most recent 2019-02-21. 23 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.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
