OGDENSBURG prefixes in area code 315

NANPA records 6 assigned NXX blocks to rate center OGDENSBURG in area code 315, 0.8% 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. 4 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (2), ONVOY, LLC- NY (2), TC SYSTEMS, INC. - NY (1). 5 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 680, 920 – overlay codes cover the same geography, so a rate center is served by all of them.
