Hi, Sonja and welcome!
My name is ***** ***** I will be happy to assist you today.
You can retrieve your TSA Known Traveler Number (KTN) by going to the following website or calling the number below. The Universal Enrollment Center is not open on weekends, so at this time, you'd be better off filling in the form at the site below and in that way, you will find your KTN.
Universal Enrollment Service: 855 -347- 8371
Hours: Mon.- Fri. 8AM-10PM, Eastern time.
I hope this helps.
