NYS DEC Update
NYS DEC Update - As of August 1, 2024, DEC is changing from printing sporting licenses and all items sold through DECALS on special license stock (Valeron) to printing on plain paper. This change will allow DEC to become more cost effective, keep up with emerging technologies, and help reduce our carbon footprint. Customers will still be able to purchase their licenses in-person at an issuing agent, online, or over the phone. When purchasing a license in-person, the customer will have the option of having their license, tags, and other items emailed to them rather than printing them at the point of sale. This change is effective for the 2024-25 license year and will begin with sales starting August 1, 2024. Additionally, lifetime license holders should expect to receive their 2024-25 licenses and tags on plain paper by September 1, 2024. The change to plain paper does not apply to the spring 2024 turkey season.
