Flint, MI Area Code

Area code serving Flint

Flint sits in Michigan, part of the Midwest region and the Eastern Time zone. Its area code is 810, which covers eastern Michigan including Flint, Port Huron and the Thumb area. 810 has no overlay today, so every Flint landline and mobile number with a local code starts with 810.

810 has served the area since 1993. If the region runs low on numbers, regulators will most likely add an overlay code on top rather than split the area, which would make 10-digit dialing mandatory.

Getting a Flint phone number

Any new landline, mobile or VoIP number from a local carrier in Flint gets the 810 area code. Numbers come from the blocks each carrier holds in the area; a number ported in from elsewhere keeps its original area code, so you may also see out-of-state codes locally.

Dialing in Flint

Flint is covered by the single area code 810 with no overlay, so some local calls may still connect with seven digits. Dialing all 10 digits (area code + seven-digit number) always works and is the safest habit. From outside the US, dial +1, then the area code and number.
