Lansing, MI Area Code

Area code serving Lansing

Lansing sits in Michigan, part of the Midwest region and the Eastern Time zone. Its area code is 517, which covers south-central Michigan including Lansing, Jackson and Adrian. 517 has no overlay today, so every Lansing landline and mobile number with a local code starts with 517.

517 has served the area since 1947, as one of the original 1947 North American area codes. 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 Lansing phone number

Any new landline, mobile or VoIP number from a local carrier in Lansing gets the 517 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 Lansing

Lansing is covered by the single area code 517 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. See 10-digit dialing and overlay area codes for the background. For every code in Michigan, visit the Michigan area codes page.
