MTWASHIGTN prefixes in area code 502

NANPA records 5 assigned NXX blocks to rate center MTWASHIGTN in area code 502, 0.7% of the 735 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. 5 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - KY (1), METROPCS, INC. (1), WINDSTREAM KENTUCKY WEST, INC. (1). The earliest assignment on record here is 2001-06-12 and the most recent 2022-01-11. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
