WASHINGTON prefixes in area code 724

NANPA records 30 assigned NXX blocks to rate center WASHINGTON in area code 724, 3.8% of the 783 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. 11 holders hold those blocks, the largest being VERIZON PENNSYLVANIA, INC. (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - PA (6), LEVEL 3 COMMUNICATIONS, LLC - PA (4). The earliest assignment on record here is 2001-01-31 and the most recent 2006-06-23. 21 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 207, 252, 309, 319 – overlay codes cover the same geography, so a rate center is served by all of them.
