BRITTON prefixes in area code 405

NANPA records 36 assigned NXX blocks to rate center BRITTON in area code 405, 4.6% 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. 7 holders hold those blocks, the largest being SOUTHWESTERN BELL (23), COMCAST IP PHONE, LLC (5), TELEPORT COMMUNICATIONS AMERICA OK - LLC (3). The earliest assignment on record here is 2001-10-05 and the most recent 2016-06-27. 26 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 517, 572, 605 – overlay codes cover the same geography, so a rate center is served by all of them.
