SNFC MT-EV prefixes in area code 415

NANPA records 61 assigned NXX blocks to rate center SNFC MT-EV in area code 415, 7.8% of the 785 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. 14 holders hold those blocks, the largest being PACIFIC BELL (28), T-MOBILE USA, INC. (5), BANDWIDTH.COM CLEC, LLC - CA (5). The earliest assignment on record here is 2001-05-11 and the most recent 2014-11-11. 40 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 628 – overlay codes cover the same geography, so a rate center is served by all of them.
