FTCOVINGTN prefixes in area code 518

NANPA records 4 assigned NXX blocks to rate center FTCOVINGTN in area code 518, 0.5% of the 775 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 TWC IP ENABLED SERVICES, LLC (1), VERIZON NEW YORK, INC. (1), TELXMEDIA, INC. - NY (1). The earliest assignment on record here is 2010-09-07 and the most recent 2017-04-17. 4 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 838 – overlay codes cover the same geography, so a rate center is served by all of them.
