YUKON prefixes in area code 405

NANPA records 10 assigned NXX blocks to rate center YUKON in area code 405, 1.3% 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. 4 holders hold those blocks, the largest being SOUTHWESTERN BELL (4), ONVOY, LLC - OK (4), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2013-07-05 and the most recent 2021-03-08. 7 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 572, 724 – 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.
