If you are a member of the TSA PreCheck® Application Program, you may call (855) 347-8371 weekdays, between 8 a.m. and 10 p.m. ET, to make changes to your name, address, or other information contained in your records. You may also submit your inquiry online. You will be provided information regarding documentation needed to process the change.
If you change your name and do not update your TSA PreCheck® membership to match the new details, you will not be able to use your TSA PreCheck® benefits when traveling until the name change process is completed.
