9. Frequently Asked Questions (FAQ)

Is the ETA mandatory for babies and very young children?

Yes. Regardless of age, every child, even a toddler , must have their own ETA if they are a national of a country covered by the scheme. No age is exempt.

Do I need to create a separate account for each child when applying?

No. ETA applications for minors can be made through the parent or guardian's account , provided the minor's information is correctly entered on the form.

Is a parental consent letter always required?

The authorization letter is mandatory if the child is traveling alone or accompanied by a third party (non-parent). It is not necessary if the child is traveling with both parents .

Can a non-biometric passport be used for a minor?

In most cases, a biometric passport is recommended . Some non-biometric passports may cause problems during the automated analysis of the application.

Do I need to reapply for an ETA if my child changes passports?

Yes. Since the ETA is linked to the passport number , any document renewal requires a new ETA application , even if the old one is still valid.

Is there expedited processing for child ETA applications?

There is no official “urgent” procedure. However, most applications are processed quickly by the British government , often within 48 hours if the application is complete.
