AMSTERDAM prefixes in area code 518

NANPA records 14 assigned NXX blocks to rate center AMSTERDAM in area code 518, 1.8% 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. 8 holders hold those blocks, the largest being PAETEC ITEL, LLC (4), VERIZON NEW YORK, INC. (4), LEVEL 3 COMMUNICATIONS, LLC - NY (1). The earliest assignment on record here is 2002-05-16 and the most recent 2002-05-16. 12 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 660, 740, 838 – overlay codes cover the same geography, so a rate center is served by all of them.
