NOSYLVANIA prefixes in area code 734

NANPA records 4 assigned NXX blocks to rate center NOSYLVANIA in area code 734, 0.6% of the 701 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 ONVOY, LLCV - MI (1), NUSO, LLC (1), SKYE TELECOM LLC DBA SKYETEL (1). The earliest assignment on record here is 2021-07-02 and the most recent 2021-10-25. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
