BRISTOL prefixes in area code 423
NANPA records 38 assigned NXX blocks to rate center BRISTOL in area code 423, 5.0% 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. 10 holders hold those blocks, the largest being UNITED TELEPHONE-SOUTHEAST-TN DBA CENTURYLINK - TN (9), NEW CINGULAR WIRELESS PCS, LLC - GA (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (8). The earliest assignment on record here is 2001-11-14 and the most recent 2026-09-28. 26 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 262, 276, 401, 469 – overlay codes cover the same geography, so a rate center is served by all of them.
