Effective September 26, 2005, U.S. passports can no longer be amended to change items appearing on the data page (Name, Date of Birth, Place of Birth, Gender, Date of Issuance, Date of Expiration).
Endorsements not affecting the information on the data page of the passport may still be added. Additional visa pages may still be attached to existing passports.
There will be a 30-day grace period during the initial implementation process for passports that have already been submitted.
This change does not affect passports already issued.
