Guide: Understand EAN invoicing for the public sector
Have you landed your first government client and are you about to invoice for your work?
Are you confused by words like EAN number, NemHandelsregisteret and OIOUBL format?
Entering the EAN space can seem daunting and confusing, so if you're left wide-eyed and wondering, don't despair.
We've put together a thorough guide to help you feel safe and secure when sending EAN invoices.
What is an EAN invoice?
An EAN invoice is an electronic invoice using an EAN number (European Article Number), which is a digital invoicing method that can be used between companies in Denmark's NemHandelsregister and public institutions. EAN invoicing is often used by public institutions and larger companies to handle invoices more efficiently and automate accounting processes.
CVR vs. EAN - What's the difference?
CVR is an abbreviation for "Central Business Register" and is the state register and information portal for Danish companies.
All Danish companies must be CVR-registered and have a CVR number. However, with a few exceptions for companies with an annual turnover of DKK 50,000 or less.
EAN, on the other hand, is an abbreviation of "European Article Numbering".
An EAN number is used for invoicing to public bodies such as municipalities, regions or companies that are registered in NemHandelsregisteret.
Whereas CVR invoicing is primarily done via email with an invoice attached as a PDF file or via letter, invoicing to the public sector is done through e-invoicing via an EAN number.

- Easily invoice both the public and private sector
- Minimize manual errors
There are different accounting systems that you can use to create an e-invoice, which we will introduce you to at the end of this post.
EAN invoicing for the public sector
In order to be able to send an EAN invoice to the public sector you first need to get hold of the 13-digit EAN number, whereas with a regular invoice you would invoice via a CVR number instead.
The EAN number can be seen as the electronic address of the institution or company and ensures that your invoice ends up in the right place.
You can find out the EAN number of the company or institution you need to invoice, either directly or by searching on their website.
An institution with multiple departments may have different EAN numbers, which is a good idea to be aware of when invoicing.
There may also be some public recipients who invoice via their CVR number.
When the company receives an EAN invoice, they can then pay via their system. If you don't invoice via an EAN number to these entities, your invoice will be rejected.
