It is a common misconception that the TSA performs a "credit check" for programs like TSA PreCheck; they actually perform a criminal background check and a threat assessment. In 2026, most applicants receive their Known Traveler Number (KTN) in 3 to 5 days after their in-person appointment. The actual appointment, where you provide fingerprints and proof of citizenship, typically takes less than 10 minutes. However, the TSA notes that some applications can take up to 60 days if there are complexities in the background check or if additional documentation is required. You can check your status online at any time during the process. Once approved, the membership lasts for five years before requiring a renewal, which can usually be done entirely online in 2026 without a second in-person visit, provided your information hasn't changed significantly.
