Historical Timeline of Area Code 329

Area code 329 was created on March 24, 2023 as an all-services overlay of area code 845 in New York's Mid-Hudson Valley. The overlay was necessitated by the 988 Suicide and Crisis Lifeline implementation, which forced 845 into mandatory 10-digit dialing in October 2021 and accelerated number exhaustion projections from Q3 2024 to Q3 2023.

Key milestones:

2021: Mandatory 10-digit dialing took effect in the 845 NPA on October 24, 2021, earlier than the national deadline. NANPA filed a petition on November 30, 2021 requesting relief (Case 21-C-0600). Source: NY PSC Case 21-C-0600

Regulatory History
