What is a Passport Card, and Can it Substitute a Passport?

If you’ve ever submitted an application for a new passport (or handled the forms for a passport renewal), you might have noticed the option to obtain a passport card as well.

Both the passport book and passport card serve as valid identification for U.S. citizens and noncitizen nationals, aiding in travel, but they have important differences. Here’s what to consider when choosing between the two.

What distinguishes a passport book from a passport card?

Both passport books and cards include essential details about the holder, such as full name, nationality, place of birth, gender, issue date, expiration date, a unique ID number, and a photograph.

Here’s how they differ:

Cost

Passport cards are more affordable than passport books. For first-time applicants of a passport book, the fee is $165 ($135 for those under 16). Renewals for passport books are $130, regardless of age. In contrast, the initial cost for passport cards is $65 ($50 for minors), and renewals are $30. Both options remain valid for 10 years for adults and five years for individuals under 16 at the time of issuance.

Where (and when) you can use them

A U.S. passport book allows travelers to enter any country and territory that welcomes Americans (though some may require prior visa arrangements) by air, land, or sea. Conversely, passport cards are limited to land or sea travel between the U.S. and Canada, Mexico, the Caribbean, and Bermuda, and cannot be used for international air travel.

Keep in mind that both options are Real ID compliant and can be utilized for domestic flights.

Appearance

The typical passport book measures by 5 inches and comes in a navy blue cover, featuring a title page with the holder’s personal details and 28 blank pages for visa stamps (received upon entering or exiting countries other than the United States). Passport cards are wallet-sized and resemble a driver’s license.

Are passport cards a worthwhile investment?

Since passport books cover all aspects of international travel, they are generally a better option for most individuals than passport cards. However, there are situations where a passport card makes sense—such as when traveling solely by land or sea, or if you’re on a tight budget and need to cross a border. According to the Department of State, "The passport card was specifically created for the needs of northern and southern U.S. border communities whose residents frequently cross the border by land."

Alternatively, you could opt for both. The passport card’s compact size makes it convenient to carry as a backup form of ID.
