Moving within NJ, does your FID become invalid?

 

I know I probably can't buy guns with it, since my FID and DL won't technically match with the change of address sticker on back.

 

Could I still legally buy handgun ammo? They never checked my DL Iirc but I'm wondering if I legally have to turn my fid in.

I just went through the change of address proccess and held onto my FID until the new one was issued for exactly that reason. Was able to buy ammo without a problem and just turned in my old one to the PD when I picked up the replacement.

 

It's not your fault it takes ~6 months to get a replacement card so I'd say you're good to go. A FID is the only requirement but even if they do ask for your license i doubt they'd see the sticker on the back unless you pointed it out.

I am going through the same situation, I am moving at the end of this week.  I plan on telling my new local PD that it was lost in the move.  Someone correct me if I am wrong but I have always been under the impression that they require you to turn in your old FID when you apply for the change of address.

The only time a FPID becomes invalid is if you become a prohibited person.  The PD may require you to turn it in with the application for change of address, or they may request it when they give you the new one.  They may also request new fingerprints if you "lost" it.  All PDs do something different and you are at their mercy.  This is also true with dealers if you do not get an updated FPID.  The dealer may request an updated FPID if you were to attempt to acquire a firearm or ammunition, even though it still is valid with the old address.
