US Passport Cover Colors Explained
In the United States, your passport cover color instantly signals your travel authority and legal status to customs and immigration authorities at international border checkpoints.
Blue Cover: Standard Regular Passport
The traditional blue cover passport is the standard regular passport carried by over 160 million American citizens. First introduced in 1976 for the US Bicentennial, it represents the primary document issued for private, vacation, and business travel.
Maroon / Red Cover: Official Passport
Issued to US government employees, active-duty military personnel, and select contractors traveling internationally to execute official government business. Holders cannot use an official passport for personal leisure vacations.
Black Cover: Diplomatic Passport
A diplomatic passport features an iconic black cover and represents the highest level of diplomatic accreditation. Issued to Foreign Service Officers, ambassadors, Cabinet secretaries, and the President of the United States.
Dark Green Cover: Travel Document / Re-entry Permit
While ordinary US passports used green covers prior to 1976, modern green covers are issued by US Citizenship and Immigration Services (USCIS) as Refugee Travel Documents or Re-Entry Permits for lawful permanent residents.
Passport Book vs. Passport Card
When completing passport application forms, applicants can choose between a passport book, a passport card, or both. Understanding their legal differences prevents costly travel mistakes.
Critical Rule: Passport Card Is Not Valid for International Air Travel
A passport card is a wallet-sized alternative designed only for land and sea border crossings. The card is not valid for international air travel anywhere in the world. If you board an international flight, you must possess a traditional passport book.
| Feature | US Passport Book | US Passport Card |
|---|---|---|

The passport card is a wallet-sized photo identity card equipped with a proximity RFID chip for fast border vehicular lane processing (Ready Lanes) when driving between the United States, Canada, Mexico, Bermuda, and returning via Caribbean sea cruise ports.
What is Passport Type P on the Data Page?
If you look at the laminated biometric data page of your passport book, you will find the letter P positioned in the top-left field labeled Type / Type.
Under ICAO Document 9303 machine-readable travel document conventions, Type P designates a Personal or Regular Passport. This indicates that the document belongs to an individual private citizen rather than an official envoy (Type O) or diplomat (Type D).
Where Code "P" Appears on Your Passport ID Page:
- Type Field: Located at the upper left corner of the biodata page right above your 3-letter issuing country code (e.g.,
USA). - Machine Readable Zone (MRZ): The first character of the 44-character bottom optical code line begins with
P<USA..., denoting passport booklet format. - Visa Pages: Behind the biographical data page lie the numbered visa pages designed to hold physical entry and exit stamps and consular visa stickers.
