STEWARTSTN prefixes in area code 717

NANPA records 3 assigned NXX blocks to rate center STEWARTSTN in area code 717, 0.4% 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. 3 holders hold those blocks, the largest being COMCAST IP PHONE, LLC (1), LEVEL 3 COMMUNICATIONS, LLC - PA (1), VERIZON NORTH, INC. - PA (1). The earliest assignment on record here is 2024-04-25 and the most recent 2024-04-25. 3 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.
