DULZURA prefixes in area code 619
NANPA records 8 assigned NXX blocks to rate center DULZURA in area code 619, 1.0% 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. 8 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1), U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (1), PACIFIC BELL (1). The earliest assignment on record here is 2001-01-25 and the most recent 2021-12-09. 7 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.
