Professional Roof Consultants (504) 561-1116
504 was one of the original area codes created in 1947, and originally covered all of Louisiana. In 1957, most of the state west of the Mississippi River was split off as area code 318. In 1998, the western portion of the old 504 territory, including Baton Rouge, became area code 225. In 2001, much of southeastern Louisiana was split off as area code 985, to both the west and the north of 504.
Several of New Orleans' downriver suburbs switched to 985 in 2001 as well. However, after Hurricane Katrina in late August 2005, much of this area switched back to 504. These communities are now being served with dialtone from telephone switching facilities in New Orleans following near-total destruction of local switching facilities due to flooding from Katrina. Permissive use of 504 alongside 985 to reach these downriver communities began on July 29, 2007. Mandatory use of 504 to again reach these communities began on May 1, 2008. These communities are on both sides of the Mississippi River in lower Plaquemines Parish, including Pointe Ã la Hache on the east bank, with Port Sulphur, Buras, and Boothville on the west bank.
