Yes, you can easily check your TSA PreCheck enrollment status and retrieve your Known Traveler Number (KTN) online through the official enrollment provider you used during your application (either IDEMIA or Telos). To check, visit the "KTN Lookup" or "Service Status" page on the provider's website—such as tsaprecheckbytelos.tsa.dhs.gov—and enter your legal name, date of birth, and the contact information used during enrollment. Most applicants are approved within 3 to 5 days, but it can take up to 60 days in some cases. If you are already a member, the online portal will tell you your expiration date, which is typically five years from the date of approval. It is important to remember that having a "Green" status online doesn't automatically mean you get PreCheck on your flight; you must ensure your KTN is manually added to your airline reservation and that the name on your ticket exactly matches the name on your PreCheck account for the indicator to appear on your boarding pass.
