SPRINGFLD prefixes in area code 719

NANPA records 5 assigned NXX blocks to rate center SPRINGFLD in area code 719, 0.8% of the 665 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. 4 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CO (2), ONVOY, LLC - CO (1), NEW CINGULAR WIRELESS PCS, LLC (1). 5 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.
