SNFC MT-EV prefixes in area code 628
NANPA records 26 assigned NXX blocks to rate center SNFC MT-EV in area code 628, 13.5% of the 193 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 NEW CINGULAR WIRELESS PCS, LLC (5), FRACTEL, LLC (5), SONIC TELECOM, LLC - CA (3). The earliest assignment on record here is 2015-10-02 and the most recent 2025-01-28. 26 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 415 – overlay codes cover the same geography, so a rate center is served by all of them.
