Thank you for using Just Answer. I am James, and I will be assisting you. As we work through your questions, think about this as a conversation. We will talk back and forth until I have all the information I need from you, and you will respond until you have all the information you need. Once you've received the information you need, you can thank me by issuing me a positive rating of 3, 4, or 5 stars. This is the only way I get credit for doing my job, so please do not forget this before leaving the site.
ANSWER: Based on my research, you have been issued a Known Traveler Number already. That is good news for you. But because this is not a secure site, I cannot provide you with the Known Traveler Number directly here. But you can and should contact the Universal Enrollment Service center to retrieve your number. You can do that on the website, or by calling the UES:
Status Check where you can put in your information and find the Known Traveler Number starting with "TT": https://universalenroll.dhs.gov/workflows?workflow=service-status
Or call 1-***-***-**** between 8am - 10pm Eastern, Mon. - Fri to retrieve it from an agent.
Once you have the Known Traveler Number, you should call the airline and ask that your Known Traveler Number be included in your reservation.
As for the approval notice, you should be receiving a letter with the Known Traveler Number enclosed, for future use.
Note that including this in your reservation does not always guarantee TSA PreCheck on every single trip. The TSA implements a random security procedure that sometimes allows for tSA PreCheck and sometimes does not.
I hope I have answered your questions. I aim to give you excellent service, even if the outcome is not what you wanted. So I am happy to answer any related follow-up questions you might have, at no additional charge.
And if you want to talk on the phone for 30 minutes, I can send you an offer for that.
Once you have received an answer, please leave a positive rating by choosing on the 3, 4 or 5 stars so I get credit for doing my job.
A BONUS is also appreciated if you feel I've earned it.
And if you have questions in the future, write FOR JAMES in the question and I will be your personal Expert in this category.
