Hello, and welcome!
I'm sorry you're experiencing a problem locating Michael's TSA number. I'm assuming you're referring to his TSA Precheck number? If you're referring to a GOES, SENTRI, TWIC OR NEXUS number, please let me know. Also, he's over 18 years old, correct?
If you know for sure that he applied, had an in person interview at an Enrollment Center, was approved, fingerprinted, and paid a fee of $85, then received a letter with the number, I suggest the following: I don't know which TSA department you spoke with, but you can try the Enrollment Services phone number, ***-***-**** or you can visit this website and fill in all requested information, to retrieve his number:
I hope this helps, and you find his number.
Please be so kind as to rate my answer with positive feedback, as that is the only way I receive recognition from the site for my assistance. Thank you very much!
