From 1 January 2021 you’ll need an EORI number that starts with XI to:
move goods between Northern Ireland and non-EU countries
make a declaration in Northern Ireland
get a customs decision in Northern Ireland
To get an EORI number that starts with XI, you must already have an EORI number that starts with GB. If you do not have one, apply for an EORI number that starts with GB as soon as possible.
If you already have an EORI number that starts with GB and HMRC thinks you need one that starts with XI, they’ll automatically send you one in mid-December 2020.
To get advice on moving goods between Great Britain and Northern Ireland sign up for the Trader Support Service.
If you sign up your business before 23 November, this will also ensure you’ll be sent an EORI starting with XI.
