WINDHAM prefixes in area code 207

NANPA records 7 assigned NXX blocks to rate center WINDHAM in area code 207, 0.9% of the 742 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 BELL ATLANTIC MOBILE, INC (2), NEW CINGULAR WIRELESS PCS, LLC - DC (2), CONSOLIDATED COMM OF NO. NEW ENGLAND-ME (2). The earliest assignment on record here is 2001-05-29 and the most recent 2020-06-22. 6 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 234, 330, 518, 838 – overlay codes cover the same geography, so a rate center is served by all of them.
