EDWARDS prefixes in area code 661

NANPA records 13 assigned NXX blocks to rate center EDWARDS in area code 661, 1.9% of the 674 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. 9 holders hold those blocks, the largest being PACIFIC BELL (4), ONVOY, LLC - CA (2), BANDWIDTH.COM CLEC, LLC - CA (1). The earliest assignment on record here is 2010-03-12 and the most recent 2013-03-12. 11 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 codes 315, 601, 680, 769 – overlay codes cover the same geography, so a rate center is served by all of them.
