CARNATION prefixes in area code 425

NANPA records 3 assigned NXX blocks to rate center CARNATION in area code 425, 0.5% of the 628 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 CENTURYTEL OF WASHINGTON, INC. DBA CENTURYLINK (1), COMCAST IP PHONE, LLC (1), FRACTEL, LLC (1). The earliest assignment on record here is 2005-03-16 and the most recent 2021-07-23. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
