GEORGETOWN prefixes in area code 937

NANPA records 9 assigned NXX blocks to rate center GEORGETOWN in area code 937, 1.2% of the 781 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (3), FRONTIER NORTH, INC. - OH (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2001-05-29 and the most recent 2012-10-17. 8 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 203, 217, 229, 302 – overlay codes cover the same geography, so a rate center is served by all of them.
