How to change your name after marriage in Missouri
Your state’s instructions
Missouri does not publish a statement requiring the Social Security update first. Updating Social Security early is still the safer order, because federal and financial records are checked against it.
Passport, vehicle, and voter records follow their own current instructions rather than one universal order.
