I've renewed my passport and thus have a completely different passport number, and a passport that runs from now to May 2024.

Does anyone know please, if I have to reapply for the ESTA, or is the old one still valid even though I will have a new passport with me when I next go to the US, with a different passport number from that on my ESTA.

Thanks.

Stuart

Please see the comment below - this has been taken from the ESTA website:

"If you obtain a new passport or there is a change to your passport information, you must apply for a new travel authorization and pay the associated fees."
