ERWIN prefixes in area code 423
NANPA records 8 assigned NXX blocks to rate center ERWIN in area code 423, 1.0% 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. 6 holders hold those blocks, the largest being ONVOY, LLC - TN (2), UNITED TELEPHONE-SOUTHEAST-TN DBA CENTURYLINK - TN (2), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2001-04-04 and the most recent 2023-08-11. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
