EL CAJON prefixes in area code 619
NANPA records 89 assigned NXX blocks to rate center EL CAJON in area code 619, 11.3% 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. 16 holders hold those blocks, the largest being PACIFIC BELL (20), NEW CINGULAR WIRELESS PCS, LLC (16), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (10). The earliest assignment on record here is 2001-06-25 and the most recent 2024-03-14. 58 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.
