ELK CREEK prefixes in area code 530

NANPA records 3 assigned NXX blocks to rate center ELK CREEK in area code 530, 0.4% of the 782 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. 3 holders hold those blocks, the largest being U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (1), LEVEL 3 COMMUNICATIONS, LLC - CA (1), PACIFIC BELL (1). The earliest assignment on record here is 2001-08-22 and the most recent 2001-08-22. 3 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 402 – overlay codes cover the same geography, so a rate center is served by all of them.
