TOMPKINSVL prefixes in area code 270

NANPA records 5 assigned NXX blocks to rate center TOMPKINSVL in area code 270, 0.7% of the 769 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), NEW CINGULAR WIRELESS PCS, LLC - GA (1), WINDSTREAM KENTUCKY EAST, INC. - LEXINGTON (1). The earliest assignment on record here is 2002-06-21 and the most recent 2010-12-29. 5 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 240, 301 – overlay codes cover the same geography, so a rate center is served by all of them.
