The Web site will allow applicants to review and correct their data prior to submitting the application, including reconfirming the passport number.
Prior to submitting an application with the required payment information, you can correct all application data fields except the passport number, passport issuing country, country of citizenship and date of birth.
If an applicant made a mistake on their passport or biographical information he or she will need to submit a new application. The associated fee will be charged for each new application submitted.
Any other mistakes may be corrected or updated by clicking “Check Status”. If the traveler made a mistake in answering the eligibility questions, please visit the CBP Info Center.
