BENICIA prefixes in area code 707

NANPA records 21 assigned NXX blocks to rate center BENICIA in area code 707, 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 PACIFIC BELL (5), T-MOBILE USA, INC. (4), ONVOY, LLC - CA (3). The earliest assignment on record here is 2001-11-29 and the most recent 2023-08-16. 19 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 369 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
