MIDWAY SUL prefixes in area code 423

NANPA records 12 assigned NXX blocks to rate center MIDWAY SUL in area code 423, 1.6% 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. 3 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (10), UNITED TELEPHONE-SOUTHEAST-TN DBA CENTURYLINK - TN (1), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2002-05-09 and the most recent 2008-03-13. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
