INDIO prefixes in area code 760

NANPA records 32 assigned NXX blocks to rate center INDIO in area code 760, 4.1% 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. 7 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (13), T-MOBILE USA, INC. (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (5). The earliest assignment on record here is 2001-04-18 and the most recent 2011-08-16. 25 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.
