EL CENTRO prefixes in area code 760

NANPA records 37 assigned NXX blocks to rate center EL CENTRO in area code 760, 4.7% 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. 13 holders hold those blocks, the largest being PACIFIC BELL (9), METROPCS, INC. (8), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (4). The earliest assignment on record here is 2001-01-25 and the most recent 2014-12-09. 29 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.
