In 1957, most of the state west of the [Mississippi River](/source/Mississippi_River) was reassigned with [area code 318](/source/Area_code_318). In 1998, the western portion of the numbering plan area, including [Baton Rouge](/source/Baton_Rouge), was renumbered with [area code 225](/source/Area_code_225) in an [area code split](/source/Area_code_split). In 2001, much of southeastern Louisiana was split off with [area code 985](/source/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, much of this area switched back to 504 in 2007. 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 [Hurricane Katrina](/source/Hurricane_Katrina). Permissive dialing of 504 alongside 985 in this area 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 à la Hache](/source/Pointe_a_la_Hache%2C_Louisiana) on the east bank, with [Port Sulphur](/source/Port_Sulphur), [Buras](/source/Buras-Triumph%2C_Louisiana), and [Boothville](/source/Boothville-Venice%2C_Louisiana) on the west bank. Prior to October 2021, area code 504 had telephone numbers assigned for the [central office code](/source/Central_office_code) 988. In 2020, *988* was designated nationwide as a dialing code for the [National Suicide Prevention Lifeline](/source/National_Suicide_Prevention_Lifeline), which created a conflict for exchanges that permit [seven-digit dialing](/source/Seven-digit_dialing). This area code was therefore scheduled to transition to [ten-digit dialing](/source/Ten-digit_dialing) by October 24, 2021.[1] ## Service area In addition to the city of New Orleans (Orleans Parish), the numbering plan area includes all of [St. Bernard](/source/St._Bernard_Parish%2C_Louisiana) and [Plaquemines](/source/Plaquemines_Parish%2C_Louisiana) parishes and most of [Jefferson Parish](/source/Jefferson_Parish%2C_Louisiana). ## Popular culture The area code inspired the name for the local [jazz](/source/Jazz) [record label](/source/Record_label) [504 Records](/source/504_Records), as well as the rap group [504 Boyz](/source/504_Boyz) and the [Old 97's](/source/Old_97's) song "504" on *[Hitchhike to Rhome](/source/Hitchhike_to_Rhome)*. Rapper 504, who has heritage in New Orleans, uses this as his stage name as well. Also the area code 504 was mentioned in Drake's hit song "Practice", from his album *Take Care*. It has also been mentioned by Lil' Wayne due to his upbringing in the 504, specifically [Hollygrove](/source/Hollygrove%2C_New_Orleans).[2] [The Soul Rebels](/source/The_Soul_Rebels) also have a song called "504" about their hometown on their 2012 EP, *Unlock Your Mind*. Their track "Greatness" from the 2019 album *Poetry in Motion* also has a lyrical reference to the area code. The New Orleanian [Hot 8 Brass Band](/source/Hot_8_Brass_Band) also reference the area code in their song "New Orleans After The City", which appeared on the soundtrack for the television series *[Treme](/source/Treme_(TV_Series))*. On [Monday Night Football](/source/Monday_Night_Football) on December 16, 2019, [New Orleans Saints](/source/New_Orleans_Saints) quarterback [Drew Brees](/source/Drew_Brees) threw his 540th career touchdown pass, breaking [Peyton Manning](/source/Peyton_Manning)’s record for most career touchdown passes in NFL history. When Brees broke the record, announcer [Joe Tessitore](/source/Joe_Tessitore) said “540 in the 504!”, referencing the area code.
