JERMYN prefixes in area code 570

NANPA records 5 assigned NXX blocks to rate center JERMYN in area code 570, 0.6% of the 782 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 PAETEC ITEL, LLC (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - PA (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (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 272, 940 – overlay codes cover the same geography, so a rate center is served by all of them.
