NEWPORT prefixes in area code 207

NANPA records 3 assigned NXX blocks to rate center NEWPORT in area code 207, 0.4% 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. 3 holders hold those blocks, the largest being BELL ATLANTIC MOBILE, INC (1), MID-MAINE TELPLUS DBA MID-MAINE COMMUNICATIONS (1), CONSOLIDATED COMM OF NO. NEW ENGLAND-ME (1). 3 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 220, 223, 252, 315 – overlay codes cover the same geography, so a rate center is served by all of them.
