QUINCY prefixes in area code 509
NANPA records 7 assigned NXX blocks to rate center QUINCY in area code 509, 0.9% of the 763 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 MCIMETRO ACCESS TRANSMISSION SERVICES LLC - WA (3), NEW CINGULAR WIRELESS PCS, LLC (1), ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (1). The earliest assignment on record here is 2019-11-05 and the most recent 2025-10-23. 6 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 217, 447, 448, 517 – overlay codes cover the same geography, so a rate center is served by all of them.
