NOVATO prefixes in area code 415
NANPA records 21 assigned NXX blocks to rate center NOVATO in area code 415, 2.7% 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. 11 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (6), NEW CINGULAR WIRELESS PCS, LLC (4), T-MOBILE USA, INC. (3). The earliest assignment on record here is 2001-12-26 and the most recent 2026-07-22. 15 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.
