FAIRBORN prefixes in area code 937

NANPA records 15 assigned NXX blocks to rate center FAIRBORN in area code 937, 1.9% 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. 8 holders hold those blocks, the largest being OHIO BELL TEL CO (6), PAETEC ITEL, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - OH (2). The earliest assignment on record here is 2002-02-21 and the most recent 2021-04-02. 12 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 326 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
