What is the validity period of a U.S. passport?

The validity period of a U.S. passport varies depending on the age of the passport holder and the type of passport issued. For individuals aged 16 years or older, a U.S. passport is valid for 10 years. However, for minors under the age of 16, the passport is valid for only 5 years. It is important to note that some countries may have different entry requirements, including minimum passport validity, so it is advisable to check the specific country's regulations before traveling. To ensure uninterrupted travel, it is recommended to renew the passport well in advance of its expiration date, ideally within 6-9 months to allow for any processing delays or unforeseen circumstances.
