NOBLE prefixes in area code 405

NANPA records 5 assigned NXX blocks to rate center NOBLE in area code 405, 0.6% 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. 3 holders hold those blocks, the largest being ONVOY, LLC - OK (3), COMCAST IP PHONE, LLC (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2016-03-04 and the most recent 2020-12-31. 5 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, 618, 706, 762 – overlay codes cover the same geography, so a rate center is served by all of them.
