BOTHELL prefixes in area code 425

NANPA records 59 assigned NXX blocks to rate center BOTHELL in area code 425, 9.4% 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. 13 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (18), T-MOBILE USA, INC. (12), ELECTRIC LIGHTWAVE LLC DBA ALLSTREAM (8). The earliest assignment on record here is 2001-03-30 and the most recent 2024-10-11. 42 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
