DESERT CTR prefixes in area code 760

NANPA records 3 assigned NXX blocks to rate center DESERT CTR in area code 760, 0.4% 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. 3 holders hold those blocks, the largest being U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (1), FRONTIER CALIFORNIA INC. (1), CENTURYLINK COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2006-12-14 and the most recent 2006-12-14. 3 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 442 – overlay codes cover the same geography, so a rate center is served by all of them.
