ELIZABTHTN prefixes in area code 423
NANPA records 13 assigned NXX blocks to rate center ELIZABTHTN in area code 423, 1.7% 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. 7 holders hold those blocks, the largest being SUNCOM DBA T-MOBILE USA (3), NEW CINGULAR WIRELESS PCS, LLC - GA (3), UNITED TELEPHONE-SOUTHEAST-TN DBA CENTURYLINK - TN (3). The earliest assignment on record here is 2001-11-07 and the most recent 2025-08-07. 10 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 223, 270, 364, 518 – overlay codes cover the same geography, so a rate center is served by all of them.
