WALPOLE prefixes in area code 508

NANPA records 14 assigned NXX blocks to rate center WALPOLE in area code 508, 1.9% of the 749 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. 7 holders hold those blocks, the largest being OMNIPOINT MIAMI E LICENSE, LLC (4), VERIZON NEW ENGLAND INC. (4), LEVEL 3 COMMUNICATIONS, LLC - MA (2). The earliest assignment on record here is 2001-02-16 and the most recent 2001-02-16. 10 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 603, 774 – overlay codes cover the same geography, so a rate center is served by all of them.
