SCRM NORTH prefixes in area code 279

NANPA records 25 assigned NXX blocks to rate center SCRM NORTH in area code 279, 16.6% 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. 10 holders hold those blocks, the largest being FRACTEL, LLC (7), ONVOY, LLC - CA (6), NEW CINGULAR WIRELESS PCS, LLC (4). The earliest assignment on record here is 2018-01-23 and the most recent 2026-05-21. 25 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.
