MANSFIELD prefixes in area code 419

NANPA records 35 assigned NXX blocks to rate center MANSFIELD in area code 419, 4.5% 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 BRIGHTSPEED OF NORTHWEST OHIO, INC. (15), NEW CINGULAR WIRELESS PCS, LLC - IL (7), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (6). The earliest assignment on record here is 2001-05-31 and the most recent 2021-07-09. 16 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, 272, 318, 417 – overlay codes cover the same geography, so a rate center is served by all of them.
