SNFC CNTRL prefixes in area code 415
NANPA records 483 assigned NXX blocks to rate center SNFC CNTRL in area code 415, 61.5% 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. 27 holders hold those blocks, the largest being PACIFIC BELL (223), NEW CINGULAR WIRELESS PCS, LLC (54), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (36). The earliest assignment on record here is 2001-03-22 and the most recent 2024-11-01. 270 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.
