EUREKA prefixes in area code 707
NANPA records 36 assigned NXX blocks to rate center EUREKA in area code 707, 4.6% 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 (8), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (7), UNITED STATES CELLULAR - CA (5). The earliest assignment on record here is 2001-05-18 and the most recent 2026-07-30. 26 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 codes 309, 369, 406, 435 – overlay codes cover the same geography, so a rate center is served by all of them.
