EVERETT prefixes in area code 425

NANPA records 121 assigned NXX blocks to rate center EVERETT in area code 425, 19.3% 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. 20 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (41), T-MOBILE USA, INC. (22), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (13). The earliest assignment on record here is 2001-01-24 and the most recent 2026-02-20. 72 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 617, 814, 857 – overlay codes cover the same geography, so a rate center is served by all of them.
