PLEASANTON prefixes in area code 830
NANPA records 11 assigned NXX blocks to rate center PLEASANTON in area code 830, 2.2% of the 496 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (3), T-MOBILE USA, INC. (2), SOUTHWESTERN BELL (2). The earliest assignment on record here is 2002-03-28 and the most recent 2022-02-08. 10 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 308, 913, 925 – overlay codes cover the same geography, so a rate center is served by all of them.
