As my TSA Known Traveler Number was close to expiring, I decided to obtain a Global Entry Number.
As I was going through the process of filling out forms and getting fingerprinted, the official in charge told me that I still have to get a separate TSA Known Traveler Number, because my Global Entry Number may not be accepted in TSA precheck when I fly domestically.

I have subsequently called the TSA, and I was told that I should stop using my TSA number and only use the Global Entry number.

I fly domestically often from PHL to visit my daughter and grandsons, and the TSA precheck comes in handy.

So, when I book flights online, do I enter my Global Entry Number (in the TSA Known Traveler Number box)?
Or should I still get a separate TSA Known Traveler Number to make sure I have it for domestic flights?

Thanks,
Sooze

I agree with above answers except that it's likely the number won't change unless it already did.

I recently migrated from straight TSA to Global Entry. I can confirm that, first, the numbers ARE different (very different); and second, that the GE number will be recognized as a KT number for domestic flights. As mentioned above, the official who told you otherwise was wrong.

I don't believe that is true, although in my case the TSA precheck number is old. But it was 9-digits and was formatted as 98xxxxxxx. It was my understanding most if not all TSA precheck numbers started with the "98". My current Global Entry number is a mix of nine numbers and characters, the first two being "TT".

When my Global Entry was expiring I applied for Nexus. My Known Traveler Number remained the same when I got my Nexus card. Mind you, mine only has numbers so maybe things have changed.
