Eligibility basics for TSA PreCheck
TSA PreCheck is available to U.S. citizens, nationals, and permanent residents who undergo a background check and in-person enrollment. There is no minimum or maximum age to apply; minors can enroll, and adults of any age can qualify if they meet the eligibility criteria. The program is designed to expedite screening for approved travelers, and age affects enrollment steps, verification needs, and what happens at the checkpoint but not the fundamental ability to join based on age alone.
How minors and families can get PreCheck
Age and documentation for applicants under 18
Children and teenagers under 18 can be included in a parent’s or guardian’s Trusted Traveler profile or apply in person with a parent or guardian present. Minors do not need a separate TSA interview if they are under 13 and enrolled with an adult. Applicants who are 13 and older may be required to appear in person or provide notarized consent if applying without a parent. Acceptable documents include a birth certificate, U.S. passport, or naturalization certificate to prove age and citizenship.
Adding minors to an existing PASS account
If you already have a TSA PreCheck or Global Entry membership, you can add eligible minors to your Known Traveler Number (KTN) through the TSA website or mobile app where supported. You will need each child’s name, date of birth, and passport or other identifying documents. After the details are verified, the KTN can be used at security checkpoints to receive PreCheck benefits. Some enrollment centers may still request an in-person visit to update a family profile.

| Known Traveler Number (KTN) | Children can be linked to an adult’s KTN for expedited checks | TSA account management help |
| Processing time for minors | Typically 3–5 business days after in-person enrollment | TSA known timelines |
What to bring to your first PreCheck appointment
During an in-person enrollment, you will submit primary identification, proof of citizenship, and a form of payment. For children, a parent or guardian must accompany them and bring their own ID along with the child’s documents. Appointments can often be scheduled through the TSA website or by calling the enrollment center. Arrive early, dress in layers, and be prepared to remove belts, shoes, and outerwear as you would at any checkpoint.
PreCheck benefits at the security checkpoint
Once approved and linked to your KTN, you may keep shoes, belts, and light jackets on, leave laptops and compliant liquids in your carry-on, and use a dedicated PreCheck lane if available. These benefits apply regardless of your age, but you must present a boarding pass and a photo ID that matches your KTN. For families, using a KTN with PreCheck allows parents and children to move through security more efficiently without additional screening for minors who are correctly enrolled.
Common scenarios and edge cases
Traveling with infants and toddlers
Infants do not need boarding passes for domestic flights and usually are held in a parent’s arms through security, but linking them to a KTN can simplify family processing. You may carry breast milk, formula, and baby food in reasonable quantities for screened items. Checkpoint officers may swab bottles or liquids, so allow a few extra minutes. Being proactive about documentation can reduce questions and ensure a smoother experience.
Teens traveling alone or with friends
Travelers aged 13 and older who are approved for PreCheck can use lanes independently. Carry the boarding pass and a valid photo ID, such as a passport card or state ID, that displays the KTN. If traveling without a parent, some minors may need notarized documentation depending on airline or destination requirements. Always confirm airline boarding policies in advance, as they can differ from TSA security rules.
Global Entry and families
Global Entry includes TSA PreCheck benefits and requires in-person enrollment for applicants of all ages. Parents or guardians can apply for themselves and include children in the same application or in a separate appointment. The extra cost for Global Entry is worthwhile for frequent travelers who value customs pre-clearance along with expedited security. Once approved, the benefits apply worldwide at participating airports and on all flights that use PreCheck lanes.
Maintaining and renewing PreCheck
TSA PreCheck is typically valid for five years from the date of approval, after which you must renew to keep benefits. Minors who were approved at a young age will need to renew before their KTN stops providing PreCheck privileges. Renewal can often be done in person or online, depending on your status and age. Keep your KTN handy when booking flights and check for any changes in documentation requirements before each trip.
Tips for smooth checkpoint experiences
- Check that your boarding pass and ID display the same name and KTN.
- Enroll children with trusted adults when possible to avoid last-minute issues.
- Carry printed or digital copies of approvals for reference during travel.
- Arrive with extra time during peak travel periods even with PreCheck.
- Review airline-specific rules, as carriers may have additional requirements for minors.
Bottom line
There is no specific age threshold to qualify for TSA PreCheck; both children and adults can be members if they meet identity, citizenship, and background check requirements. Families can enroll minors under 13 with a parent, while teens 13 and older may need to appear in person or provide consent. Knowing the documentation rules, using a KTN, and confirming checkpoint procedures help ensure a consistent PreCheck experience at any age.
