The ETA is not a visa or travel document, but a certificate that provides additional verification of the traveller. Obtaining it does not guarantee entry to the UK and the traveller will still be subject to border control.

The ETA is linked to the passport under which it is issued. A new passport requires a new ETA certificate.

An ETA authorises multiple entries to the UK for a period of two years from the issue of the certificate, or until the passport associated with it expires.

Those exempt from the ETA requirement include:

• those with an appropriate visa or leave to remain in the UK;
• those flying in transit;
• those with citizenship, living in and travelling from Ireland;
• those exempt from immigration control under separate legislation.

The cost of obtaining an ETA is £16.

Applications for an ETA can only be made electronically, via an app or the government website.
