Why Is Your TSA Precheck Not Working How To Fix It

TSA PreCheck is a program designed to simplify airport security screenings for travelers. Sometimes, however, travelers may find that their TSA PreCheck is not working correctly. So, why is your TSA PreCheck not working?

In this article, we will explore the various reasons why your TSA PreCheck may not be working and provide you with some practical tips on how to troubleshoot and fix the problem.

Why Is Your TSA PreCheck Not Working? 

The first reason your TSA PreCheck may not work is due to TSA PreCheck’s expiration. Another reason could be incorrect information or out-of-date information. Yet another reason your TSA PreCheck isn’t working could be that TSA PreCheck has not been added to your boarding pass.

Let’s explore these reasons and more below:

Expiration Of TSA PreCheck

TSA PreCheck is valid for five years, after which you will need to renew your membership. Your TSA PreCheck could not be working if it has expired.

Your TSA PreCheck information may not be updated or may contain errors. Make sure that all of your personal information is correct, and that it matches the information on your government-issued ID.

TSA PreCheck Isn’t Added To Boarding Pass

Your TSA PreCheck may not have been added to your boarding pass. Make sure that you have added your TSA PreCheck Known Traveler Number (KTN) to your reservation before you check in for your flight.

Unavailability of TSA PreCheck For A Particular Flight

Your TSA PreCheck status may not be available for that particular flight. TSA PreCheck is not available for all flights or all airlines, so it’s possible that you won’t be able to use it on a particular trip.

[FIXED] TSA PreCheck Not Working

To fix TSA PreCheck not working: make sure that you’re eligible for TSA PreCheck. You’ll need to check if all your personal information is up-to-date and accurate. If anything has changed since signing up for TSA PreCheck, update it on the website so that it matches the government’s records. 

You can also contact the TSA directly to find out why they are unable to verify your status. TSA offers customer service over the phone and online chat support in order to help troubleshoot any problems quickly. 

Next, check your expiration date. It’s important to make sure that your membership hasn’t expired yet. 

If it has, you’ll have to renew your membership before you can use the benefits of TSA PreCheck again. 

Verify that your TSA PreCheck number is correct and make sure it’s entered correctly each time when booking a flight.

If all else fails, try clearing your browser’s cache and cookies. This may help with any technical issues you’re having on the website or if there are any difficulties in the registration process. 

Finally, if nothing seems to work, contact TSA support directly for assistance. 

They will be able to answer any questions or concerns you might have about your TSA PreCheck membership. 

Why Is Your Global Entry Not Giving You TSA PreCheck?

If you have Global Entry but are not receiving TSA PreCheck, there may be several reasons why. First, your TSA PreCheck eligibility may have expired and needs to be renewed. Secondly, the information on your Global Entry account might not match what is in the TSA system. 

Thirdly, you need to check in with a participating airline for TSA PreCheck to work. Fourthly, make sure that you’re checking in correctly and following all the necessary steps. 

Lastly, sometimes the TSA PreCheck lane is closed or unavailable at certain airports; if this happens then you won’t be able to use it even if you are eligible for it. 

If none of these reasons seems applicable to your situation, contact your nearest Global Entry Enrollment Center or TSA PreCheck office for more help.

Why Do You Not Get TSA PreCheck With Global Entry?

Although TSA PreCheck is included as part of Global Entry, there are a few reasons why it might not appear on your ticket. The first thing to check is that all the personal information on your airline reservation and government-issued ID matches the details provided in your Global Entry application. 

If any of the data isn’t an exact match (e.g., name, date of birth), then this could mean that you won’t receive TSA PreCheck on your boarding pass. 

Another issue could be that your Known Traveler Number (KTN) – which you receive when you are approved for Global Entry – is not included on your airline reservation. 

You should make sure that you enter your KTN in the relevant section when booking a flight so it will appear on your boarding pass. 

Finally, if one of the airports that you’re flying to or from is not participating in TSA PreCheck then this could affect whether or not it appears on your ticket. 

To check ahead of time, you can use the ‘Find an Airport’ search function on the TSA website to see which airports offer PreCheck services. 

Why Is Your TSA PreCheck Not Showing On Your American Airlines Boarding Pass?

The first reason your TSA PreCheck is not showing on your American Airlines boarding pass is that your membership has not expired. Another reason your TSA PreCheck may not be working is due to incorrect data entered into your flight details.

Look up your account to check if your TSA PreCheck membership has expired.

Then, you will need to confirm with your airline that all of your information – including KTN (Known Traveler Number), name, and date of birth – is accurate and that your airline participates in TSA PreCheck®. 

If everything checks out on both ends, then you should contact the American Airlines customer service line for further assistance. 

They can hopefully provide additional insights into why you cannot see an indicator showing that you are eligible for TSA PreCheck on your boarding pass. 

Finally, if you find that your membership has expired or you discover any inaccurate information regarding your account, it is important to take the necessary steps to update and/or renew your TSA PreCheck® membership.

This will allow you to receive the indicator on your American Airlines boarding pass.

What To Do When Known Traveler Number Is Not Working?

If the issue persists, you may want to contact the airline or travel agency that you are attempting to make a reservation with. 

If they are unable to resolve the problem, you can reach out to TSA’s Contact Center for assistance. 

An agent should be able to look into the situation and provide further guidance on how to get your KTN working again. 

Do You Automatically Get Tsa PreCheck With Global Entry?
