PORT HURON prefixes in area code 810
NANPA records 44 assigned NXX blocks to rate center PORT HURON in area code 810, 8.6% of the 509 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. 15 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (10), NEW CINGULAR WIRELESS PCS, LLC - IL (5), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (5). The earliest assignment on record here is 2001-01-15 and the most recent 2025-07-01. 31 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
