I recently lost my wallet (I think I dropped it in the parking lot while shopping), and had to make a lot of phone calls to several credit card companies. Not one suggested contacting the police.
My wife recently managed to lose my card (she thinks she may have thrown it away)- I was definitely not asked to report it to the police. The company issued me a new one, put a hold on my old one, in the event that I might be able to find it, and then completely cancelled it when I activated the new card 7 days later.
You need to report it to the police IF something is charged on it. I lost my wallet and they charged about $2,000 on it. In order to get the charges taken off, I had to file a police report that the wallet was stolen and all list all the cards in it.
Then the credit card companies sent me a form. I had to list the false charges and have it notorized. Then I had to send that along with a copy of the police report. Then they took the charges off. The funny thing was I reported it in 30 minutes and charges were still being made 3 days later.
Sometimes. I had two CC’s stolen over the years, and in neither case did they ask for a police report. In one case they did ask for a notarized statement. But yes, if there are fraud charges, a police report is not unreasonable.
