Area code 225 covers the Baton Rouge metropolitan area in southeastern Louisiana. Created in 1998 from a split of 504, it reflects the state capital’s growth and political significance. Baton Rouge is a hub for education, petrochemical industries, and state government. The area code’s digits—2-2-5—also correspond to "C-A-J" on a telephone keypad, reinforcing its cultural connection to Cajun heritage. Ten-digit dialing is required. Area code 225 serves as a badge of local identity and Louisiana pride.
