CHATTNOOGA prefixes in area code 423
NANPA records 183 assigned NXX blocks to rate center CHATTNOOGA in area code 423, 24.0% of the 764 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. 33 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (60), NEW CINGULAR WIRELESS PCS, LLC - GA (25), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (21). The earliest assignment on record here is 2001-02-28 and the most recent 2025-11-26. 119 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
