About the 337 area code

Numbers under the code first appeared in 1999, when its region was separated from area code 318. Because 337 has never received an overlay, it functions as the lone code for its corner of Louisiana.
Dialing note: 337 was carved out of the 318 territory and went into service in 1999.
