Impressum Rules by Country: DE, AT and Beyond

If you run a website aimed at German-speaking countries, you've probably heard about the Impressum. It's a mandatory disclosure page with your business identity and contact details. Getting it wrong, or not having one at all, can result in fines and legal warnings.

But the rules differ significantly between countries. Germany has the strictest requirements. Austria has similar but not identical rules. Switzerland has its own version. And some countries like Belgium and UK don't require an Impressum at all, though they have their own disclosure requirements.

Germany: the strictest Impressum rules

Germany's Impressum requirement is the most detailed in Europe. Since May 2024, it's governed by §5 of the Digitale-Dienste-Gesetz, commonly shortened to DDG. Before that, the same requirement existed under §5 TMG, the Telemediengesetz. The law changed names when Germany transposed the EU Digital Services Act, but the substance remained largely the same.

Every commercial website accessible from Germany must have an Impressum. This includes business websites, online shops, blogs with advertising and even social media profiles used for business purposes.

Required elements under §5 DDG

Your German Impressum must include:

Full legal name and address. For sole proprietors, this means your personal name and a physical street address. PO boxes are not accepted.

Contact information. §5(1)(2) DDG requires "rapid electronic contact and direct communication, including the electronic mail address." The leading interpretation comes from CJEU Case C-298/07 (Deutsche internet versicherung), judgment 16 October 2008, which held that a contact form can satisfy the "direct communication" requirement only if it actually allows direct, individual and effective communication. German courts (e.g. BGH I ZR 178/08) have consistently treated this as requiring an email address plus a second channel that the operator monitors and responds to quickly. In practice, ship email plus phone, fax or a real-time messaging system.

Trade register details. If your company is registered in the Handelsregister, include the registry court and registration number. For example: "Amtsgericht Berlin Charlottenburg, HRB 12345."

VAT identification number. If you have a Umsatzsteuer-Identifikationsnummer, include it. This is different from your regular tax number, which you should not publish.

Professional regulation details. For regulated professions like lawyers, doctors, architects or tax advisors, you must list your professional chamber, your professional title and the country where the title was awarded, the applicable professional regulations and where to find them.

Editorial responsibility. If your site publishes editorial content like a blog or news section, you must name the person responsible for the content under §18 of the Medienstaatsvertrag (MStV).

Where to place it

The Impressum must be "easily recognizable, directly accessible and constantly available." In practice, this means a link in your footer or main navigation labeled "Impressum" or "Legal Notice." It must be reachable within two clicks from any page. Hiding it behind JavaScript that needs to load, or burying it in a sub-menu, is not sufficient.

Consequences of getting it wrong

Germany has a unique legal mechanism called an Abmahnung. Competitors and consumer protection organizations can send you a formal warning letter for Impressum violations. These letters often include demands for a cease-and-desist declaration and payment of lawyer fees, typically 500 to 1,500 euros.

The Abmahnung system means enforcement doesn't rely on government agencies. Your competitors can and do police this. Missing Impressum details are one of the most common grounds for Abmahnungen in Germany.

Fines from regulatory authorities can reach up to 50,000 euros for willful violations, though penalties for small businesses are typically much lower.

The TMG to DDG change in May 2024

If you set up your Impressum before May 2024, you might still reference §5 TMG. This is technically outdated. The Telemediengesetz was replaced by the Digitale-Dienste-Gesetz as Germany's implementation of the EU Digital Services Act.

The practical requirements didn't change much. The same information is required. But if your Impressum cites "gemäß §5 TMG," you should update the reference to "gemäß §5 DDG." This shows that your legal pages are current and maintained. Some Abmahnung lawyers specifically look for outdated references as evidence that a site isn't being properly maintained.

Austria: similar but under different law

Austria's Impressum requirement comes from the E-Commerce-Gesetz, specifically §5 ECG. The requirements overlap heavily with Germany's but have some differences.

Required elements under §5 ECG

• Full name and geographic address
• Email address for direct contact
• Company registration number if applicable
• VAT identification number if applicable
• Applicable supervisory authority for regulated professions
• Membership in professional chambers

Austria also has the Mediengesetz, which adds requirements for websites that publish editorial content. Under §24 and §25 Mediengesetz, you must disclose:

• The media owner and their address
• The basic editorial direction of the content
• For periodical media, a disclosure of ownership structure

In practice, many Austrian websites combine the ECG §5 Impressum and the Mediengesetz disclosures into one page.

Key differences from Germany

Austria doesn't have the Abmahnung problem to the same extent. While competitors can technically take legal action, the culture of sending warning letters is less aggressive than in Germany. Enforcement more often comes through consumer protection bodies like the Verein für Konsumenteninformation.

The financial penalties for missing or incomplete Impressum details can reach up to 3,000 euros under the ECG.

Switzerland: Impressumspflicht

Switzerland isn't in the EU but has its own website disclosure requirements. Swiss law doesn't use the term "Impressum" officially, but the practice is the same and the term is widely used.

The Swiss requirements come from several sources:

• Art. 3 UWG requires honest business practices, which includes transparent identification
• Art. 959a and 958f OR require companies to disclose their identity in business communications

For Swiss businesses, the recommended Impressum includes:

• Company name and legal form
• Address
• Email address
• UID number, the Swiss equivalent of a company registration number
• CHE number for companies in the commercial register

Swiss businesses targeting EU customers should also comply with EU requirements, particularly German rules if they're serving the DACH market.

Countries that don't require an Impressum

Not every European country has an Impressum requirement. But most have some form of business disclosure obligation.

Belgium

Belgium doesn't use the term "Impressum" but has equivalent disclosure requirements under two regimes:

• Wetboek van Economisch Recht (WER) / Code de droit économique, Book XII (art. XII.6), which transposes the EU E-Commerce Directive: any information society service must display its name, geographic address, contact details (including an email address that allows direct and effective communication), trade-register number (KBO/BCE), VAT number, and, for regulated professions, the supervisory body.
• Wet van 11 maart 2003 (LSSI), which mirrors the same Directive's general information duties.

For Belgian businesses, the required disclosures are:

• Company name and legal form
• Registered geographic address (street address, not PO box)
• Email address (with rapid response capability)
• KBO/BCE number (Belgian company register)
• BTW/TVA number
• For regulated professions: professional chamber and applicable rules

These are typically placed in the footer or on a dedicated "Legal Notice" / "Colofon" / "Mentions légales" page. Bilingual labelling matters in Brussels and Wallonia. A Dutch-only footer on a site that solicits French-speaking customers leaves you exposed under WER Book VI fair-trading rules; the safest pattern is a dual NL/FR label (and English if you serve EU-wide customers). Enforcement is through the FOD Economie / SPF Économie. Disclosure breaches are sanctioned under WER Book XV penalty bands, not the European Accessibility Act, and the FOD typically opens with a compliance warning rather than a fine.

If your site targets both Germany and Belgium, a German-compliant Impressum will generally satisfy Belgian requirements as well, but add your KBO number.

Netherlands

The Netherlands doesn't require an Impressum page either, but Dutch businesses must publish their business identity under the Handelsregisterwet and the Dutch implementation of the E-Commerce Directive. The required fields in a Dutch footer are:

• KvK number (Chamber of Commerce registration)
• BTW-identificatienummer (VAT-ID)
• Trade name and legal form
• Geographic address (no PO box)
• Email address

Enforcement runs through the Autoriteit Consument & Markt (ACM) and the KvK. Practice is warning-first for disclosure breaches; the ACM has stronger teeth (turnover-based fines) for misleading commercial practices.

United Kingdom

The UK doesn't have an Impressum requirement. But under the Companies Act 2006 and the Electronic Commerce Regulations 2002, UK businesses must show:

• Company name
• Registered office address
• Company registration number
• VAT number if applicable
• Contact email address

Other EU countries

Most EU countries have implemented some version of the E-Commerce Directive's Article 5, which requires provider identification. But the German and Austrian implementations are among the most detailed and strictly enforced. If your website targets multiple European markets, following the German requirements will generally satisfy everyone else's requirements too.

How to create an Impressum

Here's a practical template for a German-compliant Impressum:

Impressum

Angaben gemäß §5 DDG

Max Mustermann
Musterstraße 1
12345 Musterstadt
Deutschland

Kontakt:
Telefon: +49 123 456789
E-Mail: info@example.de

Umsatzsteuer-Identifikationsnummer gemäß §27a UStG:
DE123456789

Handelsregister: Amtsgericht Musterstadt
Registernummer: HRB 12345

Verantwortlich für den Inhalt nach §18 Abs. 2 MStV:
Max Mustermann
Musterstraße 1
12345 Musterstadt

Adapt this based on your business type. Not every field applies to every business. Sole proprietors without a Handelsregister entry skip that section. Businesses without editorial content skip the §18 MStV section.

Don't use a generator blindly. Online Impressum generators can help with structure, but you need to verify the output. Generators sometimes include outdated legal references or miss fields specific to your business type.

Where to place it on your site

The placement rules are similar across German-speaking countries:

• Link in the footer on every page, labeled "Impressum"
• Reachable within two clicks from any page
• Don't combine it with your privacy policy. They should be separate pages.
• The link must be visible without scrolling on mobile
• Don't use JavaScript-only rendering. The page should work with JavaScript disabled.

For social media profiles on Facebook, Instagram and LinkedIn, include the Impressum information in your profile or About section. The German courts have confirmed that business social media profiles need Impressum details too.

Common Questions

Do I need an Impressum if my website is in English?

If your website is accessible from Germany and targets German customers, yes. The language of your site doesn't matter. What matters is whether German consumers can access your services.

Can I use a PO box instead of my home address?

In Germany, no. The address must be a physical location where you can be reached. Sole proprietors who work from home and don't want to publish their home address sometimes use a registered business address service, but this is a grey area.

What if I have both a German and Dutch website?

Your German-facing website needs a full Impressum under §5 DDG. Your Dutch website needs KBO and BTW-ID disclosure. If you use one website for both markets, include both sets of requirements. A German Impressum satisfies Dutch requirements too, but not the other way around.

Do I need to update my Impressum from TMG to DDG?

It's recommended. The legal requirements haven't changed, but referencing the current law shows your site is maintained. Some view an outdated legal reference as evidence of negligence, particularly in the context of Abmahnungen.

Does the Impressum need to be a separate page?

In Germany and Austria, yes. Don't fold it into your privacy policy or terms and conditions. It should have its own dedicated page with a clear link labeled "Impressum" or "Legal Notice."
