INDIO prefixes in area code 442
NANPA records 24 assigned NXX blocks to rate center INDIO in area code 442, 6.7% of the 356 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. 10 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (6), FRACTEL, LLC (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (3). The earliest assignment on record here is 2015-01-16 and the most recent 2026-06-04. 24 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 760 – overlay codes cover the same geography, so a rate center is served by all of them.
