ROSAMOND prefixes in area code 661
NANPA records 7 assigned NXX blocks to rate center ROSAMOND in area code 661, 1.0% 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. 6 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - CA (2), BANDWIDTH.COM CLEC, LLC - CA (1), PACIFIC BELL (1). The earliest assignment on record here is 2016-09-26 and the most recent 2016-09-26. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
