Yes. If a child is from a nationality that requires a UK ETA, the child must have their own UK ETA before traveling to the United Kingdom.
The UK ETA children requirement applies individually.
This means that each traveler needs a separate UK ETA, including babies and children.
A parent, guardian, or family member may apply on behalf of a child.
However, the application must be completed using the child’s actual passport details, personal information, and required photo information.
A child’s UK ETA will be linked to the passport used in the application, so the passport information must match the passport used for travel.
