Correct a Data or Printing Error
A passport issued with a data error (e.g., name, sex, or place of birth) or printing error (e.g., data is missing on the biographical page, discoloration, crooked printing, etc.) can be corrected at no charge if the passport is still valid.
To correct a data or printing error:
- Complete Form DS-5504.
- Submit form by mail with your passport, one color photo, and evidence of the error (e.g. your U.S. birth certificate showing the correct spelling of your last name).
- You will not have to submit any fees.
The validity of the new, corrected passport depends on when you report the error.
