Historical Timeline of Area Code 225
Area code 225 was created on August 17, 1998, when Louisiana's area code 504 was split to provide relief for the Baton Rouge capital region. It was Louisiana's first new area code in 41 years, following the 1957 creation of area code 318. The split was authorized by NANPA Planning Letter PL-NANP-123 on June 9, 1998, covering 10 parishes centered on East Baton Rouge Parish.
Key milestones:
- 1947: Area code 504 assigned to all of Louisiana as one of the original 86 North American area codes.
- 1957: Area code 318 split from 504 for northern Louisiana (Shreveport, Monroe, Alexandria).
- June 9, 1998: NANPA PL-NANP-123 authorized the 504 split to create 225.
- August 17, 1998: Area code 225 placed in service, covering 10 parishes including East Baton Rouge, Ascension, Livingston, and Iberville. (NANPA)
- February 22, 1999: NANPA PL-156 mandated 10-digit dialing for wireless codes in the 225/504 split region. Permissive dialing ended April 5, 1999.
- 2020: FCC established 988 as the National Suicide Prevention Lifeline. Area code 225 was exempt from the mandatory 10-digit transition because no 988-prefix conflict exists.
- 2025: NANPA projected 225 will exhaust in Q1 2048, with 41% of prefixes still inactive.
Area code 225 remains a stand-alone code with no overlay, continuing to allow 7-digit local dialing. The 41-year gap between the 318 split (1957) and the creation of 225 (1998) reflected decades of stable numbering demand in the Baton Rouge region before population growth and telecommunications expansion drove the need for relief.
Regulatory History
Area code 225's regulatory history centers on three key actions over 22 years: the 1998 authorization to split 504, the 1999 mandate for 10-digit wireless dialing, and the 2020 establishment of 988 for which 225 was exempt. Source: NANPA Planning Letters
