There are a number of things that could be causing you problems. Please ensure that your computer meets the minimum configuration requirements.
The minimum computer configuration requirement for applying for ESTA authorization is an internet browser that supports 128-bit encryption and is able to accept cookies, and has JavaScript enabled.
If your computer meets the minimum configuration requirements and you are still having technical problems, then this could be a web browser or fire wall problem. Check your internet security settings - if they are set too high, they may be blocking access to the ESTA web site. If that doesn t work try applying from another browser/computer. Finally, some ISPs may be blocked due to spam concerns, and you may have to contact your local internet service provider (ISP) for assistance.
If the system will not accept your passport number, try entering it in without any spaces between the numbers.
If the system will not accept your phone number, try to enter it again, but do not use any brackets such as ( ) or hyphens - or spaces between the numbers.
If the system will not let you go to the next page, the system may have found an error in a required field (such as an invalid Character, skipped a field, etc.) You will not be allowed to continue until these errors have been corrected. If a mandatory field (indicated by a red *) is not filled in properly, the system will continually return you to the current page.
The system WILL NOT accept special characters such as ~ or accent marks - even in a name. Use only the English letters, with no special punctuation. Please enter the name as it appears in the machine readable zone (MRZ) of your passport. This is the two lines of text with numbers and chevrons (<<<) at the bottom of the personal information page with the passport bearer s picture.
If your computer freezes up and will not let you continue, the problem is most likely with your browser or your computer capacity. You may need to use a different computer.
If you are receiving an Error Message that says “There is already an application with that passport number in the system” it is because you have applied previously and have a valid application with more than 30 days validity. If any of the biographical information is incorrect on the existing application, the application is then invalid and you must click “continue“ to proceed with the new application. The associated fee of $14 will be charged for each new application submitted.
If you are still having technical problems, please click on CBP Info Center link at the bottom of the page, click on the “Ask a Question” button on the right side of the CBP INFO Center page and submit a help request. You are required to have an email address for us to respond to. If you do not, ask someone who does to help you. Be sure to describe exactly what is happening (in English), and tell us what internet browser you are using and its version.
