ORONO prefixes in area code 207

NANPA records 4 assigned NXX blocks to rate center ORONO in area code 207, 0.5% 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. 3 holders hold those blocks, the largest being CONSOLIDATED COMM OF NO. NEW ENGLAND-ME (2), MID-MAINE TELPLUS DBA MID-MAINE COMMUNICATIONS (1), PEERLESS NETWORK OF MAINE, LLC- ME (1). The earliest assignment on record here is 2018-02-16 and the most recent 2018-02-16. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
