ESTA, once approved, is valid for a duration of 2 years. Therefore, it is quite possible that the information you filled into the form initially, might change in this time period.

This article will provide a complete guide to the data which is modifiable in your ESTA application, the data which cannot be modified, and how you can make the required changes.

Modifiable Data in Your ESTA Form

The type of information you can change on your ESTA form depends on whether you have paid the fee or not. Before fee payment, you can make changes to any field. However, after fee payment, you can only make changes in the following areas:

  • Su dirección de correo electrónico
  • Your phone number
  • Your flight details
  • Your residential address (as long as the country remains the same)
  • Your address in the US

Note that the modifications listed above are free of cost and do not require any payment. 

How Can I Modify my ESTA Application?

You will have to enter your ESTA reference number to access your application. 

Once your application has been retrieved, you can make the necessary changes. These modifications can only be made in the fields mentioned above. 

Your application will be reviewed and the authorities will notify you within 72 hours of modifying your application.

Which Areas Cannot be Modified on my Application?

Once you have entered payment details and submitted your ESTA application, there is very less room for modifications. If any of the following data related to you has changed, then you need to apply for a new ESTA.

  • Your name
  • Your marital status
  • Tu género
  • Your passport
  • Tu país de ciudadanía

Any change in your personal circumstances since your application (eg if you got convicted or diagnosed with a contagious disease).

Note that whenever you reapply for ESTA, you will have to pay the full fee again. 


It is important that the information given in your ESTA application be accurate and up to date. If any information changes, you should modify your application. 

You can easily modify data by visiting the official ESTA website. If the data that has changed falls in the non-modifiable category, you should apply for a new ESTA.
