COLEBROOK prefixes in area code 603
NANPA records 4 assigned NXX blocks to rate center COLEBROOK in area code 603, 0.5% of the 752 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 CONSOLIDATED COMM OF NO. NEW ENGLAND-NH (1), LEVEL 3 COMMUNICATIONS, LLC - NH (1), FREEDOM RING COMMUNICATIONS, LLC (1). 4 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 code 440 – overlay codes cover the same geography, so a rate center is served by all of them.
