For those of our clients trading with Countries in the European Union, there are immediate changes to the way the UK Business's trade, whether or not you are VAT registered. HMRC have been helping businesses by automatically issuing them with a UK EORI (Economic Operator Registration and Identification) number. If HMRC have issued your business with an EORI number, they will have written to you directly. Businesses will not be able to move goods in and out of the UK without an EORI number.
