The New York State Police have created an easy and cost-free process that allows pistol/revolver licensees to complete re-certification online at -- http://troopers.ny.gov/firearms
Paper forms are also available at any New York State Police station.
Pistol/Revolver license re-certifications in New York State are currently only required for those permits originally issued before January 15, 2013. If your permit was issued before January 15, 2013, the deadline to submit your recertification is January 31, 2018.
Be advised this online process does not apply to those with permits in New York City, Nassau County, Suffolk County, or Westchester County. If you currently have a permit in any one of those locations, you must follow the requirements that are in place in that county.
