Before you go
Bring what the state asks for; the list depends on the errand.
A REAL ID application needs proof of identity, your Social Security number and proof of your Missouri address. Renewals and registrations need less. The Missouri Department of Revenue site lists the exact documents for each service at dor.mo.gov. Bring originals; copies are usually refused.
