SCRM MAIN prefixes in area code 279
NANPA records 46 assigned NXX blocks to rate center SCRM MAIN in area code 279, 30.5% of the 151 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. 22 holders hold those blocks, the largest being ONVOY, LLC - CA (9), FRACTEL, LLC (7), T-MOBILE USA, INC. (6). The earliest assignment on record here is 2018-01-23 and the most recent 2026-10-20. 46 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 code 916 – overlay codes cover the same geography, so a rate center is served by all of them.
