Is it necessary to have both a passport book and a passport card?

The passport book is your ultimate gateway to international exploration, but did you know it’s not the only identification that allows you to travel abroad? The U.S. also provides a passport card, which can be used at land borders with Mexico and Canada, as well as at certain sea ports in Mexico, Canada, the Caribbean, and Bermuda. So, how can you determine whether a passport book or a passport card is the better option for you? This handy guide will help you decide.

Passport book: the traditional choice

The passport book is the traditional 28-page navy blue document featuring an identification page followed by blank pages designated for entry and exit visas. The U.S. Department of State has been issuing passports for international travel since 1789, though this document has seen many changes over the years. The navy blue passport was first introduced in 1976 for the bicentennial; prior to that, passports were green or sometimes red. Passport books enable near-unrestricted international travel by all modes of transport, though additional visas may be required depending on your destination.

Passport card: the compact option

The passport card resembles a driver’s license in size and shape. It was introduced by the U.S. Department of State in 2008 as a budget-friendly alternative to the passport book for Americans traveling to Mexico, Canada, the Caribbean, and Bermuda via land or sea. While it’s not as powerful as a passport book, it remains a valuable document for certain travelers.

Passport card vs. book: key differences

Although both passport cards and books serve for international travel, they differ significantly in various aspects, particularly in their usage and the locations where they are accepted.

The allowed destinations

Passport books are the more comprehensive document regarding travel locations, as they are valid for all countries worldwide. In contrast, passport cards are limited to use in Mexico, Canada, Caribbean nations, and Bermuda.

The modes of transportation

Once again, passport books hold the advantage. They are valid for air travel, as well as land and sea travel. In contrast, passport cards are limited to land and sea travel only.

The expenses

The dimensions

Passport books are significantly larger and thicker than passport cards; the former is a true booklet with pages measuring 5 x inches, while the latter is about the size of a standard ID, such as a driver’s license, at 3.3 x 2.1 inches.

Should you have both a passport book and a passport card?

No, you don't need both the passport book and the card. The passport book offers greater access than the passport card, making it the preferred choice. However, if you plan to travel only by land or sea to Mexico, Canada, the Caribbean, or Bermuda, the passport card is a more economical option and could be ideal for your needs.

In summary, the passport card is mainly intended for Americans living in border towns near Mexico or Canada who frequently cross the border, as well as for seafarers heading to the Caribbean or Bermuda.

Steps to apply for a passport card

The application process for a passport card is identical to that of a passport book. First-time applicants need to complete form DS-11, present proof and a photocopy of U.S. citizenship, submit a second form of ID along with a photocopy, and include a passport photo. All documents must then be submitted in person at a passport acceptance facility.

Is a passport card considered a Real ID?

Yes, both passport cards and passport books meet Real ID requirements. This means you can use them for domestic flights, but not for international travel.

Final thoughts

Passport cards are ideal for travelers heading to Mexico, Canada, the Caribbean, and Bermuda via land or sea, while all other international journeys require a passport book.
