SAYVILLE prefixes in area code 631
NANPA records 14 assigned NXX blocks to rate center SAYVILLE in area code 631, 1.8% of the 782 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 VERIZON NEW YORK, INC. (6), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NY (2), TC SYSTEMS, INC. - NY (1). The earliest assignment on record here is 2006-02-03 and the most recent 2020-05-28. 8 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 934 – overlay codes cover the same geography, so a rate center is served by all of them.
