Area code 225 serves southeastern Louisiana, primarily covering the Baton Rouge metropolitan area and surrounding parishes such as Ascension, Livingston, and East Baton Rouge. It was created in 1998 from a split of area code 504 to better serve the capital region. Baton Rouge, Louisiana’s second-largest city and the state capital, anchors the 225 region with its strong presence in government, petrochemicals, and education—including Louisiana State University (LSU). The area code is often associated with political power, college sports, and southern hospitality. 225 is commonly used in local business branding and cultural references throughout the Capital Region. It remains a standalone area code and a strong symbol of civic identity in Louisiana.
