If the UK leaves the EU on a no-deal basis, which, despite the apparent will of parliament, is still a likely outcome, all Economic Operators Registration and Identification (EORI) numbers currently used by UK VAT registered businesses will become invalid in other EU Member States.
A guide to EORI here
Businesses are obliged to use an EORI number when undertaking customs activities in the EU. Such UK businesses will be required to obtain a new EU EORI number after the date of a No-Deal Brexit. This is because if the UK leaves via a no-deal Brexit EORI numbers recorded in the UK will no longer be deemed as obtained and registered in an EU Member State. Businesses importing or exporting (currently acquiring or dispatching) from/to the EU will need to request a replacement EORI from a Member State in the EU.
The same rules will apply to businesses in the EU 27 doing business with the UK. Their EORI numbers will also be invalid and will require replacement after a no-deal Brexit date.
We understand that EORI number applications will increase immediately after Brexit and it is very likely to take significantly more time to obtain a new one. It is further probable that filing customs declarations could be disrupted, with the result that the movement of goods cross-border will be delayed.
It is possible that some Member States may be flexible in their approach to existing/new EORI numbers. However, this cannot be guaranteed and there does not appear to be any impetuous between the 27 MS to agree a common approach.
This is yet another reason, should further evidence be required, that a no-deal Brexit will have profound and long-lasting negative impact on UK business. Those who voted Leave to reduce “red tape” will become increasing surprised at the amount of additional administration required post Brexit.
