SPRING VLY prefixes in area code 937

NANPA records 4 assigned NXX blocks to rate center SPRING VLY in area code 937, 0.5% 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. 4 holders hold those blocks, the largest being PAETEC ITEL, LLC (1), TELNYX LLC (1), OHIO BELL TEL CO (1). The earliest assignment on record here is 2014-05-15 and the most recent 2017-03-10. 4 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 329, 507, 715, 779 – overlay codes cover the same geography, so a rate center is served by all of them.
