ENON prefixes in area code 937

NANPA records 9 assigned NXX blocks to rate center ENON in area code 937, 1.2% of the 781 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 SPOK, INC. (6), OHIO BELL TEL CO (2), PAETEC ITEL, LLC (1). 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 codes 326, 804 – overlay codes cover the same geography, so a rate center is served by all of them.
