Oh that sucks 2V. Such a pain in the butt. I hope he didn't have much cash in it.
It's worth calling the gym to see if they found it - check outside in the parking lot, etc. Somebody might have taken the money and credit cards and left the rest so he wouldn't have to deal with the DMV.
It really depends on what he had in his wallet. Obviously, call the credit card companies, call the bank (especially if he had a debit card in his wallet), call the DMV and ask how to proceed for a lost license/registration (if that was in there).
If he had a medical insurance card in there, call them and let them know it was stolen.
I'd also as a PP mentioned, notify the three credit bureaus so that a fraud alert can be placed on his account. I would also contact the police department, if only so they can fill out a report in case of identity theft. When I had my identity stolen, a lot of the credit card companies/creditors I had to deal with needed a police report to put in my file, so I had to go to my PD and get one.
And also, because I've been the victim of identity theft, I'd have him look into a credit monitoring service, be it one through the credit bureaus or an outside one like LifeLock. After my identity was stolen, it was the service I purchased that let me know that collections were showing up on my credit file and it was the service that notified me when the lady tried to get a cell phone in my name.
Some of the companies usually have trial offers where you can try it for three months for a low fee...it might be worth it for the peace of mind because trust me--dealing with idiocy if someone tries to use the info in his wallet to steal his identiy is a pain in the butt.
Good luck! Hopefully someone honest will turn it in and this will be nothing more than a minor inconvenience.
Thanks everyone! It turns out it was a false alarm....he ended up finding it in his car. He looked but apparently not close enough.
I am super glad it wasn't stolen, but I hope he thinks twice next time. He just leaves his backpack (with his wallet) in an unlocked locker at the gym. I can't fathom this sort of trust. I think part of it is the fact that he is a native Vermonter. I'm a native New Yorker. In NY, you just don't do these things....and I think things are changing even in Vermont.
