HOMER CITY prefixes in area code 878

NANPA records 3 assigned NXX blocks to rate center HOMER CITY in area code 878, 1.6% of the 191 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), ONVOY, LLC - PA (1), FRACTEL, LLC (1). The earliest assignment on record here is 2020-05-27 and the most recent 2023-05-03. 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 724 – overlay codes cover the same geography, so a rate center is served by all of them.
