TSA PreCheck renewal doesn't have one single fixed price — it depends on which enrollment provider processes your application, and the differences add up to real money if you're not comparing. * Renewing online in 2026 generally runs $78 for a new five-year membership through the standard process. But go through a specific provider and the number shifts: IDEMIA charges $58.75 for online renewal or $66.75 in person, CLEAR charges $69.95 online or $79.95 in person, and Telos charges a flat $70 whether you renew online or in person. * Online renewal is also the faster option procedurally — it typically takes just 3 to 5 business days to process, and importantly, it keeps your existing Known Traveler Number the same, so you don't need to update it across airlines and booking profiles. * Whichever provider you use, the fee buys five years of eligibility for expedited security screening — keeping shoes, laptops, and light jackets on, and using a shorter, faster line at participating airports. * As with Global Entry, plenty of premium travel credit cards reimburse the TSA PreCheck fee as a statement credit, which effectively makes renewal free if your card offers that perk — worth checking before paying any provider directly.
