History of the 337 Area Code
The 337 area code was introduced on October 11, 1999. It was created by splitting from area code 318, which had previously served a much larger portion of Louisiana west of the Mississippi River.
The new area code was needed because the region was running out of number capacity due to population growth, increased mobile phone adoption, business expansion, and the communication demands of the late 1990s.
- 1999: 337 officially launched as a split from 318
- 2021: 10-digit dialing became mandatory
The 2021 dialing change was tied to the rollout of the 988 Suicide and Crisis Lifeline, which required more standardized dialing behavior across affected area codes.
Mnemonics and Number Facts
One interesting detail about 337 is that it was introduced after older number-format restrictions were relaxed, which means it can support mnemonic-style branding on modern phone keypads.
While most people do not use mnemonic combinations in everyday life, businesses sometimes use them to create memorable vanity numbers for marketing and local brand recall.
