Step 2: Complete the Online Application
Visit the official program website. For TSA PreCheck, go to TSA.gov/precheck. For Global Entry, use the Trusted Traveler Programs website. Fill out the application completely. You will need personal information. This includes your passport details and employment history.
Step 3: Schedule Your Interview
After application approval, schedule an interview. Interview locations can be busy. Book your appointment early. Some locations offer walk-in appointments. But scheduling is better. Bring required documents to your interview.
Step 4: Attend Your Interview
The interview is straightforward. An officer will verify your information. They will ask about your travel habits. They will also take your photo and fingerprints. The interview usually takes 15-30 minutes.
Step 5: Receive Your Known Traveler Number
After approval, you will get your KTN. This can take 2-3 weeks. Some applicants get approval faster. You can check your status online. Once you have your KTN, you can start using it immediately.
Using Your Known Traveler Number Effectively
Having a KTN is great. But you must use it correctly. Many travelers make simple mistakes. These mistakes can cost them time. Follow these tips to maximize your benefits.
Adding Your KTN to Airline Profiles
Add your KTN to all airline frequent flyer accounts. This ensures it is on every reservation. Most airlines have a field for KTNs in your profile. Update this information for each airline you use regularly.
Verifying PreCheck on Boarding Passes
Always check your boarding pass. Look for the TSA PreCheck indicator. It should appear on your printed or mobile boarding pass. If it is missing, see an airline agent. They can add your KTN to the reservation.
Traveling with Family Members
Children 12 and under can use PreCheck with eligible parents. Teens 13-17 must have their own KTN. Some programs include family applications. Check specific program rules for family travel.
Benefits of Having a Known Traveler Number
The benefits of a KTN are significant. They go beyond just faster security. Here are the main advantages you will enjoy.
Time Savings
Time is precious when traveling. TSA PreCheck lines are typically much shorter. According to TSA statistics, PreCheck passengers wait less than 5 minutes. Regular lines can take 30 minutes or more. This time savings adds up quickly.
Reduced Stress
Airport security is stressful. Removing shoes and unpacking bags increases anxiety. With PreCheck, you keep everything in your bags. The process is calm and efficient. This makes travel more enjoyable.
Consistent Experience
PreCheck provides a predictable security experience. The rules are the same at all airports. You know exactly what to expect. This consistency reduces travel anxiety.
Common Mistakes to Avoid
Many travelers make these common errors. Avoid them to ensure smooth travels.
Forgetting to Add KTN to Reservations
This is the most common mistake. Your KTN must be on your flight reservation. Otherwise, you will not get PreCheck benefits. Always double-check when booking flights.
Name Mismatch Issues
Your name on your KTN must match your government ID. Even small differences can cause problems. Middle names or suffixes must match exactly. Update your airline profiles to match your official name.
Assuming All Airports Have PreCheck
Not all airports participate in PreCheck. Smaller regional airports may not have dedicated lanes. Check the TSA PreCheck airport map before traveling.
Practical Tips for Known Traveler Number Success
Follow these practical tips. They will help you get the most from your KTN.
Tip 1: Apply During Promotion Periods
Many credit cards offer application fee credits. Cards like Chase Sapphire Reserve and American Express Platinum often cover Global Entry fees. Wait for these promotions to save money.
Tip 2: Renew Early
Start renewal 6 months before expiration. This ensures continuous benefits. Your KTN remains active during renewal processing. Do not wait until the last minute.
Tip 3: Use Mobile Passport Control with Global Entry
Mobile Passport Control is another free tool. It works with Global Entry. Download the MPC app from CBP. Use it when Global Entry kiosks are busy.
Tip 4: Keep Digital Copies
Save your KTN in your phone notes. Also keep it in your email. This ensures you always have access. You never know when you will need it.
Tip 5: Know the Rules
Even with PreCheck, you must follow security rules. Liquids still have 3.4-ounce limits. Prohibited items are still prohibited. Security officers can still select you for additional screening.
