Commonly known as a rider, insurance endorsements let you add, remove or alter your coverage—or make adjustments like changing your address. You might need an insurance endorsement if your living situation changes or you buy something expensive. For instance, if you get engaged, you might amend your homeowners insurance policy to add personal property coverage for an engagement ring. (USA Today)

An insurance endorsement, also called a rider, is a change to your insurance policy that adjusts your coverage. (Allstate)
