NOVATO prefixes in area code 628

NANPA records 7 assigned NXX blocks to rate center NOVATO in area code 628, 3.6% of the 193 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. 6 holders hold those blocks, the largest being T-MOBILE USA, INC. (2), TELNYX LLC (1), PEERLESS NETWORK OF CALIFORNIA, LLC - CA (1). The earliest assignment on record here is 2016-02-04 and the most recent 2024-03-06. 7 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 415 – overlay codes cover the same geography, so a rate center is served by all of them.
