EL RIO prefixes in area code 805
NANPA records 15 assigned NXX blocks to rate center EL RIO in area code 805, 1.9% of the 786 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. (7), BANDWIDTH.COM CLEC, LLC - CA (3), ONVOY, LLC - CA (1). The earliest assignment on record here is 2015-09-22 and the most recent 2022-01-13. 10 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 820 – overlay codes cover the same geography, so a rate center is served by all of them.
