The 225 area code is a significant telecommunication identifier in the southern part of Louisiana, particularly known for encompassing the Baton Rouge Metropolitan Area.

Geographical Coverage: Area code 225 serves the entire nine-parish Baton Rouge Metropolitan Area, which is the largest city within this area code's coverage. This indicates that the area code is vital for communication across a substantial and economically significant region of Louisiana.

History and Implementation: This area code was assigned on June 9, 1998, and became operational on August 17, 1998. Its establishment marked a pivotal development in the region's telecommunication infrastructure, adapting to the growing demands for phone lines and services in the area.

Origins and Significance: Area code 225 was created as a result of an area code split from area code 504. This event was notable because it represented the introduction of Louisiana's third area code and was the first new area code in the state in forty-one years. This highlights the area's growing importance and the need for expanded telecommunication capabilities.

These facts underscore the importance of the 225 area code in southern Louisiana's communication network, reflecting both its regional significance and historical development in the broader context of the state's telecommunication evolution.
