Step by step

  1. 1

    Order a certified copy of your Idaho marriage certificate from the Idaho Bureau of Vital Records and Health Statistics (or the county recorder where you married) — this certified copy is your legal proof of the new name.

  2. 2

    Update Social Security first with Form SS-5 (free); the new card takes about 7–10 business days.

  3. 3

    Take the certified marriage certificate and your updated Social Security record to an Idaho Transportation Department (ITD) driver's license office to update your driver's license or ID in person.

  4. 4

    Update your US passport (Form DS-5504 is free if issued within the last year), then banks, employer, and USPS.
