OCSD OCSD prefixes in area code 760
NANPA records 48 assigned NXX blocks to rate center OCSD OCSD in area code 760, 6.1% 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. 15 holders hold those blocks, the largest being PACIFIC BELL (15), T-MOBILE USA, INC. (7), NEW CINGULAR WIRELESS PCS, LLC (6). The earliest assignment on record here is 2001-10-18 and the most recent 2024-01-04. 30 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.
