GUTHRIE prefixes in area code 405

NANPA records 7 assigned NXX blocks to rate center GUTHRIE in area code 405, 0.9% 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 (3), ONVOY, LLC - OK (2), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2016-03-03 and the most recent 2021-07-13. 6 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 270, 572 – overlay codes cover the same geography, so a rate center is served by all of them.
