SPRINGFLD prefixes in area code 912

NANPA records 5 assigned NXX blocks to rate center SPRINGFLD in area code 912, 0.7% of the 731 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. 5 holders hold those blocks, the largest being SOUTHERN COMMUNICATIONS SERVICES, INC. (1), PLANTERS COMMUNICATIONS, LLC - GA (1), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2007-12-20 and the most recent 2021-01-26. 2 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.
