SIDNEY prefixes in area code 937

NANPA records 17 assigned NXX blocks to rate center SIDNEY in area code 937, 2.2% 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. 10 holders hold those blocks, the largest being BRIGHTSPEED OF NORTHWEST OHIO, INC. (5), NEW CINGULAR WIRELESS PCS, LLC - IL (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (2). The earliest assignment on record here is 2001-12-12 and the most recent 2024-02-06. 9 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 207, 217, 252, 254 – overlay codes cover the same geography, so a rate center is served by all of them.
