Baton Rouge, LA Area Code

Area code serving Baton Rouge

Baton Rouge sits in Louisiana, part of the South region and the Central Time zone. Its area code is 225, which covers Baton Rouge metro and surrounding parishes in southeast Louisiana. 225 has no overlay today, so every Baton Rouge landline and mobile number with a local code starts with 225.

225 has served the area since 1998. 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 Baton Rouge phone number

Any new landline, mobile or VoIP number from a local carrier in Baton Rouge gets the 225 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 Baton Rouge

Baton Rouge is covered by the single area code 225 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 Louisiana, visit the Louisiana area codes page.
