GAITHERSBG prefixes in area code 227
NANPA records 7 assigned NXX blocks to rate center GAITHERSBG in area code 227, 4.9% of the 142 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. 4 holders hold those blocks, the largest being ONVOY, LLC - MD (3), NEW CINGULAR WIRELESS PCS, LLC - DC (2), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (1). The earliest assignment on record here is 2024-01-29 and the most recent 2026-09-30. 7 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.
