If you’re a TSA PreCheck Application Program member and want to change your name, address, or other details, you can update your profile by phone at (855) 347-8371 on weekdays between 8 am to 10 p.m. ET. You can also submit a documentation-related query online. Remember, if you’ve changed your name but haven’t updated your TSA PreCheck membership, you won’t be able to use the benefits until your name change process has been completed.
