MIDWAY prefixes in area code 423

NANPA records 5 assigned NXX blocks to rate center MIDWAY in area code 423, 0.7% 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. 3 holders hold those blocks, the largest being UNITED TELEPHONE-SOUTHEAST-TN DBA CENTURYLINK - TN (2), BANDWIDTH.COM CLEC, LLC - TN (2), LEVEL 3 COMMUNICATIONS, LLC - TN (1). The earliest assignment on record here is 2015-05-20 and the most recent 2023-01-25. 4 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 334, 724, 859, 870 – overlay codes cover the same geography, so a rate center is served by all of them.
