ROCKLAND prefixes in area code 207

NANPA records 11 assigned NXX blocks to rate center ROCKLAND in area code 207, 1.5% 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. 6 holders hold those blocks, the largest being CONSOLIDATED COMM OF NO. NEW ENGLAND-ME (3), LEVEL 3 COMMUNICATIONS, LLC - ME (2), BELL ATLANTIC MOBILE, INC (2). The earliest assignment on record here is 2001-05-10 and the most recent 2018-11-07. 9 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 208, 339, 781, 814 – overlay codes cover the same geography, so a rate center is served by all of them.
