Irish Ferries and Stena Line introduce mandatory passport or passport-card checks on Ireland–UK routes

Irish citizens making the short hop across the Irish Sea by ferry can no longer rely on a driving-licence or other photo-ID. Both Irish Ferries and Stena Line confirmed that, from 28 September 2026, every passenger boarding services between Dublin, Rosslare and British ports must present either an Irish passport or the Irish passport card at check-in. The move brings sea routes into line with most airlines, which have required passports on Ireland–UK flights since February. The Department of Foreign Affairs updated its official travel advisory to reflect the change, emphasising that the Common Travel Area (CTA) continues to guarantee free movement for Irish and British citizens but does not oblige carriers to accept non-passport ID. Operators say the tighter policy is driven by security guidance from UK Border Force and Ireland’s Garda National Immigration Bureau, following a rise in attempted irregular migration via ferry ports. For business travellers the implications are immediate. Companies should instruct staff who use the busy Dublin–Holyhead, Dublin–Liverpool and Rosslare–Fishguard crossings to carry a valid passport or passport card. HR and mobility teams should also audit existing travel policies; many corporate intranets still describe the ferry routes as “passport-optional”. Employees without an Irish travel document will need to apply well in advance—the Passport Service’s standard turnaround is currently 20 working days, longer at peak times. The new rules arrive as passport demand spikes ahead of the Christmas trading season, when cross-border retail and logistics traffic intensifies. Ferry operators warn that passengers without the correct ID will be refused boarding, with no entitlement to a refund. Mobility managers should therefore include pre-boarding passport checks in travel workflows and ensure that contingency plans—such as last-minute air tickets—are in place should an employee be turned away. In the longer term, carriers hint that digital identity solutions could streamline CTA travel, but these are several years away. For now, a traditional passport booklet—or the wallet-sized Irish passport card—remains the only ticket to ride the ferries between Ireland and Britain.
