CHULAVISTA prefixes in area code 619
NANPA records 146 assigned NXX blocks to rate center CHULAVISTA in area code 619, 18.6% 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. 19 holders hold those blocks, the largest being T-MOBILE USA, INC. (33), PACIFIC BELL (28), NEW CINGULAR WIRELESS PCS, LLC (24). The earliest assignment on record here is 2001-09-19 and the most recent 2024-03-26. 121 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 858 – overlay codes cover the same geography, so a rate center is served by all of them.
