ATASCADERO prefixes in area code 805
NANPA records 14 assigned NXX blocks to rate center ATASCADERO in area code 805, 1.8% of the 786 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. 4 holders hold those blocks, the largest being PACIFIC BELL (6), T-MOBILE USA, INC. (5), U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (2). The earliest assignment on record here is 2001-03-02 and the most recent 2021-05-04. 13 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 820 – overlay codes cover the same geography, so a rate center is served by all of them.
