CRESWELL prefixes in area code 541

NANPA records 3 assigned NXX blocks to rate center CRESWELL in area code 541, 0.4% of the 783 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 ONVOY, LLC - OR (1), NEW CINGULAR WIRELESS PCS, LLC (1), CENTURYTEL OF OREGON, INC. DBA CENTURYLINK (1). The earliest assignment on record here is 2008-01-11 and the most recent 2015-12-14. 2 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 252, 458 – overlay codes cover the same geography, so a rate center is served by all of them.
