Can you travel to Europe without ETIAS after launch?

Yes, for a while. When ETIAS goes live in the last quarter of 2026, it will not be compulsory overnight. The EU is using a phased start: a transitional period of at least six months where you can still enter Europe without ETIAS if you meet every other entry condition, followed by a grace period of at least six months where it is required, with one narrow exception. That gives a window of at least a year before ETIAS becomes a hard wall at the border. Here is how the two phases actually differ, because the detail trips people up.

What happens during the transitional period?

This is the gentle phase. From the launch date, the official advice is that you should already apply for your authorisation, but a border officer will not turn you away just because you do not have one. You still need a valid passport and to meet the usual short-stay rules, including the 90/180-day limit. ETIAS is strongly encouraged, not yet enforced. The EU has said this transitional period lasts at least six months.

In plain terms: if you are travelling in late 2026 or very early 2027 and forget to apply, you are unlikely to be refused on the ETIAS point alone. That is the safety margin the EU built in so carriers and travellers can adjust. Do not read it as permission to ignore the system. Applying takes minutes and costs €20, and it removes any risk.

What changes during the grace period?

After the transitional period ends, the rules tighten. During the grace period, you generally must hold a valid ETIAS to enter the 30 European countries that require it. There is one carve-out, and it is the part most explainers get wrong: only travellers arriving for the first time since the transitional period ended may still be let in without ETIAS, again provided they meet all other conditions.

So if you visited Europe during the transitional window, that one-off leniency does not apply to your next trip in the grace period. You need the authorisation. The grace period also lasts at least six months. After it, ETIAS is mandatory for everyone in scope, with no exceptions, which the EU currently expects to be around April 2027.

When does ETIAS become genuinely mandatory?

Stack the phases together and the picture is clear. Launch in Q4 2026, then at least six months of transition, then at least six months of grace, then full enforcement from roughly around April 2027. Both periods are minimums, so the EU could extend either if the rollout needs more time. The dates are a window, not a fixed calendar entry, and we will update the ETIAS status page if they move.

The bottom line for travellers

• Right now there is nothing to apply for. Applications are not open. No action is required yet. Applications are not open. Any site charging for ETIAS today is not legitimate, see our guide to ETIAS scams.
• From launch, apply anyway. The transitional period means you probably will not be refused without it, but applying early removes the gamble and the authorisation lasts 3 years.
• Do not bank on the first-time exception. It only covers a single arrival once the grace period starts, and only if you have not travelled since the transition ended. Hold a valid ETIAS and the question never arises.
• Check whether you even need it. It depends on your nationality and destination, use the do I need ETIAS check.

ETIAS is a separate thing from the biometric border checks that are already running. For how the two systems fit together, read our EES vs ETIAS explainer. When applications do open, the only place to apply is the official EU ETIAS website.
