You will need to submit a new application if you have already submitted your application but
have made a mistake in one or more details relating to your biographical information, such as
if you’ve made an error on your name, date of birth, passport number, etc. Answering one of
the eligibility questions incorrectly will also require a new ESTA application, but if you chose
‘yes’ on one of the eligibility questions in error, then it would be best to contact CBP
directly either by calling them or sending them an email. Contact information is available at
the bottom of the page on the
ESTA website. This information is needed to determine your
authorisation, so any changes mean you’ll need a whole new application. There are some details,
however, that you can change when you check your ESTA status, such as your email address,
telephone number and the address you are staying at in the U.S.
