HOULTON prefixes in area code 207

NANPA records 6 assigned NXX blocks to rate center HOULTON in area code 207, 0.8% 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 CONSOLIDATED COMM OF NO. NEW ENGLAND-ME (3), OXFORD CNTY TELEPHONE SVC CO, DBA OXFORD NETWRKS (1), COMMIO, LLC (1). The earliest assignment on record here is 2011-09-15 and the most recent 2021-10-20. 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 code 715 – overlay codes cover the same geography, so a rate center is served by all of them.
