STRASBURG prefixes in area code 717

NANPA records 4 assigned NXX blocks to rate center STRASBURG in area code 717, 0.5% 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. 4 holders hold those blocks, the largest being PAETEC ITEL, LLC (1), LEVEL 3 COMMUNICATIONS, LLC - PA (1), VERIZON PENNSYLVANIA, INC. (1). 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 217, 223, 234, 303 – overlay codes cover the same geography, so a rate center is served by all of them.
