Hello, Ellen and thanks for your question.
My name is ***** ***** I will be glad to help.
After your in person interview and fingerprinting, plus paying the fee, you should receive a letter with your KTN (Known Traveler Number) from TSA within a few days to a few weeks.
The website you were given (I'll give you a better one, below), is to fine out your status and you can also get your KTN, if it has already been generated. Try this website, below, but wait a few days since you just went through your interview/fingerprinting process.
You can also call the Universal Enrollment Service to find out your status and KTN number, once it has been generated:
855- 347- 8371 Hours: 8AM-10PM Mon - Fri Eastern time.
I hope you found this helpful!
Please be so kind as to rate my answer with positive feedback, as that is the only way I receive recognition for my assistance. Thank you very much!
