Stena Line and Irish Ferries are introducing stricter identification requirements for passengers travelling by ferry between the Republic of Ireland and Britain.

From Monday, September 28th, 2026 next, passengers, including children, will need to present a valid passport when checking in for affected sailings.
Stena Line says the requirement will apply in both directions on its Dublin–Holyhead route and Rosslare–Fishguard route.
No alternative forms of identification will be accepted by Stena Line.
The company is contacting customers who already have bookings.

Irish Ferries has similarly announced that all passengers, including Irish and British citizens, travelling between the Republic of Ireland and Britain in either direction must carry a valid passport. Its announcement also advises Irish passengers to check that their passport or Irish passport card is in date.
The operators say the change is required to comply with UK Border Force rules concerning the accuracy and integrity of passenger information collected before boarding.

This new passport rule appears to be part of the UK’s move towards a more digital, automated border system, requiring ferry operators to provide accurate, verifiable passenger information before departure. Passports make it easier to confirm travellers’ identities, nationalities and immigration permissions, so the measure is connected to immigration and border security in that operational sense; however, authorities have not linked it to any particular immigration incident or increase in illegal migration. It does not alter the Common Travel Area rights of Irish and British citizens, who remain exempt from visas and the UK’s Electronic Travel

What were the previous rules?
Under the Common Travel Area, Irish and British citizens are not generally legally required to present a passport when travelling between the two countries.
UK government guidance still says that Irish and British citizens travelling from Ireland to Great Britain may establish their identity and nationality using documentation other than a current passport.

Previously, ferry companies could accept alternative identification from Irish and British passengers. Depending on the operator and passenger’s age, this could include a driving licence or other official photographic ID.
Irish Ferries’ earlier guidance also said that British and Irish passengers under 18 without photographic identification could usually travel with a birth certificate.

This new requirement is therefore principally a stricter carrier check-in policy. It does not remove the travel and residency rights enjoyed by Irish and British citizens under the Common Travel Area.
Government guidance also makes clear that ferry operators may impose their own documentary requirements.

The change does not affect Stena Line’s services from Belfast to Liverpool, Cairnryan or Heysham. Passengers using other routes or operators should check the identification rules applying to their particular booking before travelling.
