GEORGETOWN prefixes in area code 530
NANPA records 6 assigned NXX blocks to rate center GEORGETOWN in area code 530, 0.8% of the 782 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 ONVOY, LLC - CA (2), PACIFIC BELL (1), IP HORIZON LLC (1). The earliest assignment on record here is 2020-11-13 and the most recent 2023-08-10. 6 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.
