Here's another tip that can save you alot of time and stress if you lose, or have stolen, your wallet/purse:
Take every scrap of ID and credit/debit cards out of your wallet or purse and xerox the front and back of every piece. Staple the sheets into a packet and tuck the packet into your safe, deposit box, or secure storage.
In the event your wallet/purse is lost/stolen, retrieve this packet to be able to quickly and efficiently contact all of your creditors/banking institutions to cancel or block your accounts. The service phone numbers are right on the back of each card which save you time and stress from having to look up the numbers or play follow the bouncing phone until you finally get a correct referrel number. You can also contact the SSA, DMV, etc. of your lost IDs so that computer notices can be generated to prevent your ID from being used in a fraud crime. Also report any access badges to prevent illegal entry into your workplace or school buildings.
Just remember to update your stored packet whenever an account is added/deleted or when a new expiration date is issued. Shred whatever is removed.
