HUMMELSTN prefixes in area code 717

NANPA records 6 assigned NXX blocks to rate center HUMMELSTN in area code 717, 0.8% of the 784 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 VERIZON PENNSYLVANIA, INC. (2), WINDSTREAM D & E SYSTEMS, INC. - PA (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2001-05-16 and the most recent 2001-05-16. 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 code 223 – overlay codes cover the same geography, so a rate center is served by all of them.
