PULLMAN prefixes in area code 509

NANPA records 14 assigned NXX blocks to rate center PULLMAN in area code 509, 1.8% of the 763 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. 7 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (7), T-MOBILE USA, INC. (2), INLAND CELLULAR LLC (1). The earliest assignment on record here is 2002-05-16 and the most recent 2026-05-11. 11 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 269 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
