WILLIAMSTN prefixes in area code 856
NANPA records 25 assigned NXX blocks to rate center WILLIAMSTN in area code 856, 3.7% of the 676 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. 12 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NJ (4), LEVEL 3 COMMUNICATIONS, LLC - NJ (3). The earliest assignment on record here is 2001-09-21 and the most recent 2026-08-24. 19 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 252, 304, 315, 413 – overlay codes cover the same geography, so a rate center is served by all of them.
