Modify Your Application
Update your existing ESTA application details before final approval. Quick and secure modification process.
Understanding Application Modifications
Once your Electronic Travel Authorization has been approved, certain pieces of information can be updated without needing to submit an entirely new application. This modification capability is designed to accommodate the reality that travel plans evolve — accommodation details change, contact information is updated, and itineraries are adjusted as departure dates approach.
However, it is important to understand the distinction between modifiable and non-modifiable information. Core identity details that were used in the security screening process cannot be altered on an existing authorization. Changes to these fundamental fields require a completely new application submission.
Information You Can Update
Information That Requires a New Application
Certain core personal details are permanently linked to your authorization and the security screening that was conducted during processing. If any of the following details need to be changed, you must submit a fresh application with the correct information:
How to Modify Your Application
To update modifiable information on your approved authorization, you will need your application reference number and the passport details associated with your application. The modification process is straightforward and typically takes only a few minutes to complete. Changes to modifiable fields take effect immediately and do not require additional processing time.
When making modifications, ensure that all updated information is accurate and current. While changes to travel details do not affect your authorization's validity, providing accurate information helps ensure a smooth experience at U.S. ports of entry. Border officials may reference your application details during the admission process.
If you are unsure whether your specific change qualifies as a modification or requires a new application, our support team can advise you. Providing your reference number when contacting support allows us to quickly assess your situation and recommend the appropriate course of action.
Important Considerations
Modifications to your application do not reset the validity period of your authorization. Your ESTA remains valid for the original two-year period from the date of initial approval, regardless of how many times you update your travel details. Similarly, modifications do not trigger a new security screening — your original approval remains in effect.
If you have obtained a new passport since your authorization was approved, even if all your personal details remain the same, you must submit a new ESTA application linked to your new passport. Your authorization is directly tied to the specific passport number used during the original application, and a new passport number constitutes a fundamental change.
