THE DALLES prefixes in area code 541

NANPA records 14 assigned NXX blocks to rate center THE DALLES in area code 541, 1.8% 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. 8 holders hold those blocks, the largest being UNITED TELEPHONE - NORTHWEST DBA CENTURYLINK - OR (3), METROPCS, INC. (2), LEVEL 3 COMMUNICATIONS, LLC - OR (2). The earliest assignment on record here is 2001-08-17 and the most recent 2008-02-14. 10 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 458 – 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.
