WASCO prefixes in area code 661
NANPA records 8 assigned NXX blocks to rate center WASCO in area code 661, 1.2% 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. 8 holders hold those blocks, the largest being IP HORIZON LLC (1), LEVEL 3 COMMUNICATIONS, LLC - CA (1), TWILIO INTERNATIONAL, INC. (1). The earliest assignment on record here is 2019-10-04 and the most recent 2022-06-29. 7 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 541 – overlay codes cover the same geography, so a rate center is served by all of them.
