SNMN SNMN prefixes in area code 310
NANPA records 84 assigned NXX blocks to rate center SNMN SNMN in area code 310, 10.7% of the 786 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 FRONTIER CALIFORNIA INC. (39), SPOK, INC. (10), METROPCS NETWORKS, LLC (7). The earliest assignment on record here is 2001-04-19 and the most recent 2006-11-07. 32 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 424 – overlay codes cover the same geography, so a rate center is served by all of them.
