GEORGETOWN prefixes in area code 720

NANPA records 11 assigned NXX blocks to rate center GEORGETOWN in area code 720, 1.4% of the 785 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 BANDWIDTH.COM CLEC, LLC - CO (5), ONVOY, LLC - CO (3), TELNYX LLC (1). The earliest assignment on record here is 2010-07-19 and the most recent 2021-10-26. 11 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.
