ETIWANDA prefixes in area code 909

NANPA records 10 assigned NXX blocks to rate center ETIWANDA in area code 909, 1.3% 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 BANDWIDTH.COM CLEC, LLC - CA (2), FRONTIER CALIFORNIA INC. (2), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2005-09-30 and the most recent 2020-09-28. 9 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 840 – overlay codes cover the same geography, so a rate center is served by all of them.
