SPRINGFLD prefixes in area code 937

NANPA records 42 assigned NXX blocks to rate center SPRINGFLD in area code 937, 5.4% of the 781 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. 11 holders hold those blocks, the largest being OHIO BELL TEL CO (12), NEW CINGULAR WIRELESS PCS, LLC - IL (7), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (5). The earliest assignment on record here is 2001-06-26 and the most recent 2022-11-17. 28 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 208, 217, 225, 326 – overlay codes cover the same geography, so a rate center is served by all of them.
