I have several of these for different types of papers and locations. I have one in the kitchen for temporary filing of pay stubs, paid bills and other papers to be filed in the long term storage. I have another for receipts divided by type (work, grocery, gifts, charitable etc). I even have one in the car with insurance info, maintenance, accident forms etc. There is one that houses our important documents so I have them all together.
I made photo copies of all the papers to keep copies in our Go Bags, fire safe and safety deposit box. These photo copies will work until extra copies can be ordered and swapped out. I keep them in waterproof map bags but Ziploc freezer bags will work. Also part of these papers are copies of photo IDs and group family photos. This way if someone is separated from the group and does not have their ID the family photo will prove they belong to your group.
This is smart for your pets as well. If their tags get misplaced or a microchip reader is not available a photo of you and your pet will show they belong to you. You could even go as far as paw print cards. They are similar to the child finger print cards they give out at safety fairs. When I was a teen and worked with sporting dogs many owners had the dogs' ear tattooed with a name or number unique to the owner such as their last name or social. This practice has been replaced with micro-chipping but this only works if there is a chip reader.
DO NOT keep copies of any of these papers in your car or out in the open! This can make life easy now but can lead to identity theft later on.
