Children aged 12 and under may use tsa precheck with a parent who has an active membership, provided you follow the steps to ensure the indicator appears on their boarding pass. Children aged 13 and older must obtain their own separate membership to access these expedited security lanes.
The age of your child and whether you already hold an active membership are the two factors that determine if you need to pay for an additional application. This guide explains the requirements for different age groups and how to manage the process for your family.
When your child needs their own PreCheck
This page serves parents who are currently enrolled in the program and want to bring their children through security without delays. If you’re a parent with an active membership, your children aged 12 and under don’t need to apply for their own status. They will receive the indicator on their boarding pass as long as it appears on yours, provided you’re traveling on the same reservation.
If you aren’t yet a member, you must first complete the application process for yourself. This page assumes you already have a Known Traveler Number (KTN) and are looking to extend those benefits to your dependents. Parents whose children are teenagers—aged 13 to 17—should prepare to pay the full application fee for each child, as they’re treated as individual applicants. This page doesn’t cover the process for children traveling with non-members, as they won’t receive expedited screening in that scenario.
Factors that change the outcome
The primary factor is the age of the child at the time of your flight. Children 12 and under automatically qualify for the expedited lanes when traveling with an eligible parent, while those 13 and older must hold their own membership. If you try to use the lane for a teenager who doesn’t have their own KTN, the system won’t grant them access, and they will have to use the standard security line.
Another factor is the airline you choose for your trip. While most major domestic carriers participate, it’s your responsibility to verify that your specific airline supports the program. You can check the current list of participating airlines on the TSA website. If your airline doesn’t participate, your KTN won’t provide any benefits, regardless of the passenger’s age.
Documentation is the third factor that often causes confusion. Even if your child is under 12, always carry a copy of their birth certificate or a similar form of identification when traveling. If you encounter a system error where your child’s boarding pass doesn’t show the indicator, a physical document helps the officer verify their age quickly.
Steps to register a teenager
- Visit the official enrollment website to start a new application for your child.
- Fill out the online form with your child’s personal information, including their full legal name and date of birth.
- Pay the application fee, which is a modest cost for a five-year membership.
- Schedule an in-person appointment at an enrollment center for your child.
- Bring your child to the appointment with the required identity documents, such as a passport or birth certificate.
- Provide a secondary form of identification, like a social security card or student ID, if requested by the agent.
- Wait for the notification email, which typically arrives within 3 to 5 business days after the appointment.
- Locate the KTN in the notification and save it in your records.
- Add the KTN to your child’s airline profile for every future booking.
The most common mistake parents make is failing to add the KTN to the airline reservation after receiving it. Even if your child has an active membership, the benefit won’t apply unless the number is explicitly entered into the “Known Traveler Number” field during the booking process or at check-in.
Membership options at a glance
| Situation | Action required | Typical cost | What to watch for |
|---|---|---|---|
| Child under 12 | None needed | $0 | Ensure KTN is on your ticket |
| Child 13-17 | New application | $78 | Needs in-person interview |
| New parent member | Enroll yourself | $78 | Must be approved first |
| Membership renewal | Renew online | $69 | Do this 6 months early |
For children under 12, the primary mistake parents make is assuming the child needs a separate account. If you don’t add their Known Traveler Number to your existing booking, they will be denied expedited screening.
Teenagers aged 13 to 17 face a stricter threshold. Because they’re legally minors, they must bring a parent or guardian to the interview. If you arrive without a birth certificate or passport, the agent will cancel the appointment immediately.
New parents should prioritize their own approval before attempting to add family members. If you try to bundle applications before your own status is confirmed, the system will reject the entire batch. You’ll then have to pay separate processing fees for each individual.
The six-month window for renewals isn’t a suggestion. If you wait until your membership has less than 90 days remaining, you risk a lapse in coverage. Once a membership expires, you lose your grandfathered status and must pay the full application fee again.
Use this decision rule to save time: If your expiration date is more than 180 days away, wait for the automated email prompt. If your date is within 90 days, log in to the portal manually today to avoid a total loss of benefits.
Details that impact your success
Document preparation
Successful applicants ensure their child’s documents match the information provided in the online form exactly. If the name on the birth certificate differs from the name on the application, you may face delays or rejection at the enrollment center. Always check the spelling of the middle name and ensure that suffixes like “Jr.” Or “III” are included if they appear on the government-issued documents.
The interview process
An in-person interview is mandatory for all children aged 13 and older. During this meeting, the agent will verify the child’s identity and take their fingerprints. Parents should accompany their children to this appointment to provide consent and assist with the paperwork. If your child is nervous, explain that the agent will simply ask a few basic questions to confirm their identity.
Common issues and fixes
| What you notice | What it usually means | What to do first | How to stop it happening again |
|---|---|---|---|
| No indicator on pass | KTN missing | Re-enter number in booking | Save KTN to airline profile |
| Name mismatch error | Spelling error | Check airline reservation | Use exact legal name |
| Reservation split | Records unlinked | Contact the airline support | Book all tickets together |
| KTN not accepted | Airline not in program | Verify airline status | Check list before booking |
The most common mistake is assuming a saved profile automatically updates existing reservations. It does not. If you add your Known Traveler Number to your frequent flyer account after booking, you must manually refresh the reservation or call the airline to force a re-scan of your data. Failure to do this often results in a lost PreCheck status for that specific flight.
Name mismatches frequently occur due to middle names. If your ID includes a middle name but your ticket does not, the system may flag you for manual screening. Always match your ticket to the name on your government-issued ID exactly. If you have a suffix like “Jr.” Or “III,” ensure it’s included in the name field, not the last name field.
If your reservation is split, it’s usually because you booked a multi-city itinerary or added a passenger after the initial purchase. When this happens, the airline creates two separate PNRs. You must ensure the KTN is attached to both records individually.
If you only update one, the secondary passenger will be denied expedited screening. Always verify your boarding pass for the “TSA PreCheck” logo at least 24 hours before departure. If it’s missing, you have exactly 12 hours before flight time to resolve the error with the airline’s help desk.
Rules for family travel
The program is governed by the Transportation Security Administration, which sets the age limits and requirements for all travelers. You can find the most current rules regarding family members and minors directly on the official government portal. Note that these rules are subject to change, so verify the requirements before you pay any application fees for your children.
If your child is 13 or older, they must provide their own biometrics and pass a background check. There are no exceptions to the in-person interview requirement for teenagers, regardless of their status as a minor.
If you have concerns about the background check process, the agency publishes a detailed list of disqualifying offenses on their website. Never attempt to use your own KTN for your teenager’s reservation, as this will lead to a mismatch and may result in the loss of your own membership privileges.
Costs and time commitments
The cost for a new membership is quite affordable and covers five years of service. This fee is non-refundable, so ensure you have all the necessary documents before you begin the application.
While the online form takes about 15 minutes to complete, the in-person appointment can take up to 30 minutes depending on the volume of applicants at your chosen center. If you arrive during peak hours—typically Tuesday through Thursday between 11:00 a.m. and 2:00 p.m.—expect wait times to double.
Costs can increase if you choose to use third-party services that assist with the application process. These services often charge additional processing fees, which provide no extra benefit. To keep costs at the minimum level, always use the official government website.
Many applicants mistakenly pay for expedited processing services offered by private firms. These companies can’t accelerate the government’s internal review timeline. If a site asks for a fee higher than the standard government rate, you’re likely on a third-party portal.
Keep in mind that some credit cards offer a statement credit that covers the application fee. Check your card’s benefits page to see if you qualify for this reimbursement. If you hold a premium travel card, verify if this specific membership is listed under your travel incidental credits. This simple check can effectively reduce your total out-of-pocket expense to zero.
Maintaining your child’s status
Once your child has their own KTN, the membership is valid for five years. You’ll receive an email notification when it’s time to renew. You can renew the membership online, and it generally doesn’t require a second in-person interview. If your child’s status expires, they will no longer be eligible for the expedited lanes, and you’ll need to pay the renewal fee to restore access.
The most common mistake parents make is assuming the KTN carries over automatically when a child turns 18. At this milestone, the child must transition to an adult membership tier. Failing to update this profile results in a rejected status at the gate, forcing the family into standard security lines. If your child is approaching their eighteenth birthday, initiate the account transition at least 60 days in advance to avoid a gap in coverage.
Check your child’s boarding pass for the indicator every time you travel. If the indicator is missing, visit the airline check-in counter before you proceed to security. They can often add the KTN manually if it was left off during the booking. If you change your airline or if the airline updates its computer system, double-check that the KTN is still correctly linked to the new reservation.
Use this simple decision rule to verify your status: if the boarding pass shows “TSA PRE” or a similar clear identifier, proceed to the expedited lane. If the pass is blank or shows “TSA PRE” only for the parent, stop at the desk. Don’t assume the agent at the checkpoint can fix a missing KTN. They lack the system access to modify your reservation details.
By verifying the boarding pass at the check-in counter, you save an average of 20 to 40 minutes of wait time at the security checkpoint. Always keep a digital copy of the KTN confirmation letter in your phone’s cloud storage to provide proof if the airline’s system fails to sync correctly.
When to seek other options
If your child is 13 or older and you’re concerned about the background check, you might consider other programs like CLEAR. This is a private service that uses biometrics to verify identity, but it doesn’t replace the security screening itself. It’s a different service that works alongside the program, and it has its own separate fees and requirements.
If you’re a frequent international traveler, consider Global Entry instead of a standard membership. Global Entry includes the expedited security benefit for your child, but the application process is more rigorous and requires an interview at a Global Entry enrollment center.
These centers are less common than standard enrollment sites, so you may need to travel further for the appointment. If you’re unsure which program fits your travel habits, compare the benefits and locations of the centers near your home before starting an application.
Frequently asked questions
Can my child use my KTN?
Children aged 12 and under can use your KTN, but children 13 and older must have their own. If your child is 12 or younger, the indicator will appear on their boarding pass automatically when they’re on your reservation. For teenagers, the system requires a separate account and a verified number for each person.
How long does the approval take?
Most applicants receive their KTN within 3 to 5 business days after their in-person interview. In some cases, it may take up to 60 days if the background check requires additional review. You can check the status of your child’s application by logging into the official enrollment website using the application ID provided.
Is it safe to provide my child’s data?
The process is handled directly by the government, which uses encrypted systems to protect all personal information. You should only provide sensitive data through the official website ending in .gov. Avoid any site that asks for your child’s information if it doesn’t have this specific domain, as these are often unofficial third-party sites.
What happens if the indicator is missing?
If the indicator is missing, you must speak with an airline agent at the check-in desk to link your KTN to the reservation. If they can’t resolve it at the desk, your child will have to go through the standard security line. Always bring your child’s birth certificate to the airport just in case you need to verify their age.
Does it matter which airport I use?
The program is available at most major airports in the United States, but you should verify your departure airport on the official website before you travel. If your specific airport doesn’t have a dedicated lane, you won’t be able to use the service there. Check the airport list on the government portal to confirm your route.
Can I renew my child’s membership online?
Yes, you can renew your child’s membership online up to six months before it expires. The renewal process is typically faster than the initial application and usually doesn’t require another in-person interview. Ensure you keep your contact information updated in the portal so you receive the renewal reminder email.
Conclusion
Start by checking your own KTN status on your current airline reservation to ensure your own travel is set up correctly. If your child is under 12, confirm they’re on your booking, and if they are 13 or older, complete the online application for them today. If you have any trouble with the online portal, contact the official help desk listed on the government website for direct assistance.
