BURTON prefixes in area code 440

NANPA records 10 assigned NXX blocks to rate center BURTON in area code 440, 1.3% of the 757 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 LEVEL 3 COMMUNICATIONS, LLC - OH (2), ONVOY, LLC - OH (2), AMERICAN MESSAGING SERVICES, LLC (2). The earliest assignment on record here is 2016-03-01 and the most recent 2024-10-07. 8 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 217, 979 – overlay codes cover the same geography, so a rate center is served by all of them.
