NEWPORT prefixes in area code 423
NANPA records 15 assigned NXX blocks to rate center NEWPORT in area code 423, 2.0% 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. 8 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (4), NEW CINGULAR WIRELESS PCS, LLC - GA (2), UNITED STATES CELLULAR - TN (2). The earliest assignment on record here is 2005-07-01 and the most recent 2015-05-20. 11 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 207, 220, 223, 252 – overlay codes cover the same geography, so a rate center is served by all of them.
