SNMN SNMN prefixes in area code 424
NANPA records 35 assigned NXX blocks to rate center SNMN SNMN in area code 424, 7.6% of the 460 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. 15 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - CA (6), T-MOBILE USA, INC. (4), NEW CINGULAR WIRELESS PCS, LLC (4). The earliest assignment on record here is 2006-05-16 and the most recent 2026-05-21. 35 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 310 – overlay codes cover the same geography, so a rate center is served by all of them.
