For US citizens flying to and from Mexico, the rule is straightforward.
Air travel requires a valid US passport book. A passport card is not accepted for international flights, so a book is the document you need when you fly.
It is also wise to check that your passport has enough validity left for your trip, since some situations call for extra months beyond your travel dates. If you need to get or renew one, see how much a US passport costs and plan for processing time.
If you drive across the border or arrive by sea, you have more document options.
US citizens traveling by land or sea can use a valid US passport book, a US passport card, or certain other approved documents. The passport card is a lower-cost option designed for exactly this kind of travel between the US and neighboring countries.
Rules can differ for children and for specific crossings, and requirements are set by government authorities that can update them. Always confirm current entry rules with official sources before you go, for both the US and Mexico.
A smooth trip comes down to getting documents and details in order early.
Check your document needs based on how you will travel, and give yourself time if you need to apply for a passport. Confirming your legal status questions can help too, as covered in nationality vs citizenship.
