On a U.S. passport application, “Jr.” goes in the dedicated suffix field, which sits directly after the last name box. Where does “Jr.” go on a passport application matters mostly because the State Department wants suffixes kept separate from the last name itself, not crammed in beside it. If your name is John Doe Jr., you write “Doe” in the last name field and “Jr” in the suffix field.
The Suffix Field on DS-11 and DS-82
Form DS-11, used by first-time applicants and anyone who has to apply in person, has a separate “Suffix” field in the applicant information section. Form DS-82, the mail-in renewal form, follows the same layout. Either way, print clearly in black ink. If you make a mistake, start over with a fresh form. White-out and crossed-out corrections aren’t accepted.
Don’t try to fit “Jr” or “III” into the last name box. The form is designed to keep the suffix out of the surname, and that separation carries through to how your name is stored and printed later.
Adding or Dropping a Suffix That Doesn’t Match Your Documents
The State Department’s Foreign Affairs Manual takes a relaxed approach to suffixes. You can add one to your passport even if it isn’t on your birth certificate, and you can leave one off even if it is. This is your choice on Form DS-11.1Department of State Foreign Affairs Manual. 8 FAM 403.1 Name Usage and Name Changes – Section: 8 FAM 403.1-5(B) Name Suffixes
The usual worry about paperwork mismatches doesn’t really apply to suffixes. The FAM treats them differently from other name components. A gap between “John Doe” on your birth certificate and “John Doe Jr.” on your application won’t cause a rejection the way a mismatched first or last name would.
Roman Numerals and Interchangeable Suffixes
The State Department considers “Jr.” and “II” interchangeable, and “Sr.” and “I” interchangeable. You can pick whichever you prefer, and family naming doesn’t have to follow strict logic. A grandfather can be “John Smith I” and the grandson “John Smith II” with no “John Smith Jr.” in between. Suffixes can also skip generations.1Department of State Foreign Affairs Manual. 8 FAM 403.1 Name Usage and Name Changes – Section: 8 FAM 403.1-5(B) Name Suffixes
One formatting rule is worth knowing. If your other documents use Arabic ordinals like “2nd” or “3rd,” the State Department converts those to Roman numerals on the passport. “2nd” becomes “II,” “3rd” becomes “III.” Write the Roman numeral version on your application and you’ll skip any back-and-forth.1Department of State Foreign Affairs Manual. 8 FAM 403.1 Name Usage and Name Changes – Section: 8 FAM 403.1-5(B) Name Suffixes
One edge case: if “Sr.” is being used as an abbreviation of the Spanish “Señor,” it’s a title rather than a generational suffix. In that situation it’s treated as a prefix and generally won’t appear in the passport name field.
How the Suffix Prints on the Finished Passport
On the data page of the passport book, the suffix appears as part of your printed name. John Doe Jr. would typically show as “DOE, JOHN JR” in the visual inspection zone at the top of the page.
The machine-readable zone at the bottom of the data page is different. Suffixes are stripped out of the MRZ entirely. The two coded lines that border agents and kiosks scan don’t include “Jr.,” “Sr.,” “II,” or anything similar. That follows international standards for machine-readable travel documents, which remove prefixes and suffixes from the encoded name.2Study in the States. SEVIS Name Standards
So some automated systems that read your passport will never see your suffix. That’s by design and doesn’t cause travel problems.
Booking Flights and Trusted Traveler Profiles
A common follow-up question: does the suffix on your passport need to match your airline ticket? No. TSA’s Secure Flight system doesn’t consider suffixes when matching a reservation to your identity, and airlines actively discourage entering suffixes into the passenger name field.3American Airlines. Passenger Name Field
Book flights using just your first and last name as they appear on your passport. Most booking systems have no dedicated suffix field, and forcing one into the last name box can create problems that wouldn’t otherwise exist.
If you have TSA PreCheck or Global Entry, your Trusted Traveler profile should match your passport name. Global Entry members who change anything about their passport name need to visit an enrollment center to update the profile.4U.S. Customs and Border Protection.

Fixing a Suffix That’s Wrong on an Issued Passport
If your passport arrives with the wrong suffix, or missing one that should have been included, the State Department treats it as a data error. You can get a corrected passport at no charge while the current one is still valid.5U.S. Department of State. Name Change for U.S. Passport or Correct a Printing or Data Error
To fix it, mail in Form DS-5504 with your current passport, one color passport photo, and evidence of the correct name, such as a birth certificate showing the suffix. There’s no fee unless you want expedited processing.
Timing changes what you get back. Report the error within one year of issuance and your replacement is valid for a full ten years. Report it after one year and the replacement is only valid until your original passport’s expiration date.5U.S. Department of State. Name Change for U.S. Passport or Correct a Printing or Data Error
This is different from a legal name change. If you legally changed your name and want the suffix added or dropped more than a year after issuance, you’ll need to renew through DS-82 by mail or apply in person with DS-11, along with the usual fees and a certified name change document.
