Travelling between Ireland and Britain is straightforward, but the identification requirements depend on your nationality. Below, you'll find everything you need to know about passports, visas, and Electronic Travel Authorisations (ETAs) when travelling between Ireland and the UK.
Do Irish and British Citizens Need a Passport to Travel Between Ireland and Britain?
Irish and British citizens do not legally require a passport to travel between Ireland and Britain due to the Common Travel Area (CTA). However, all travellers should carry a valid form of photo identification, as proof of identity and nationality may be required.
Accepted Forms of Identification
- Valid passport
- Photographic driving licence
- Government-issued photo ID card
- International student card
- Health insurance or social security photo ID
- Photographic bus or train pass
- Work ID with a photograph
Although a passport is not mandatory, we recommend travelling with one whenever possible.
Travelling with Children
British and Irish citizens under 18 years of age who do not have photo identification can usually travel using a birth certificate.
I'm an EU Citizen – Do I Need a Passport or Visa for Britain?
If you are an EU, EEA, or Swiss citizen travelling to Britain, you must carry a valid passport for the duration of your stay.
Can I Use My National ID Card?
In most cases, EU national identity cards are no longer accepted for entry into the UK. Travellers should use a valid passport instead.
Do I Need a UK Visa?
For visits of up to six months, many EU citizens will only require an ETA. However, a visa may be needed for work, study, or long-term stays. Always check the latest UK Government guidance before you travel.
Passport Requirements for Non-UK and Non-Irish Citizens
If you are neither a UK nor Irish citizen and are travelling between Ireland and Britain, you must travel with a valid passport.
This requirement applies in both directions:

Depending on your nationality, you may also require:
- A UK Electronic Travel Authorisation (ETA)
- A UK visa

Advanced Passenger Information (API)
For ferry journeys between Ireland and Britain, operators are legally required to collect Advanced Passenger Information (API). This means your passport details may be scanned during check-in and shared with the relevant authorities.
Requirements for Children
Children who are not UK or Irish citizens must travel with their own valid passport and any required visa or ETA.
Do Non-EU Citizens Need a Passport and Visa?
Yes. Non-EU nationals should travel with a valid passport and check visa requirements before booking their trip.
