Sponsored Post Disclosure Rules: US, UK and Germany

Disclosure rules for sponsored posts look simple until you work across borders. Add “#ad” to a sponsored post as a creator in Manchester and you are fine. That same post, aimed at a German audience, can fall short of what German regulators expect. Rely only on Instagram’s “Paid partnership” tag in a US campaign and you ignore the FTC’s own advice.

If your brand pays creators in more than one market, you need the strictest version in your briefing. Here is how the three differ.

The principle everywhere

All three systems share one idea: people must be able to tell that content is advertising before they engage with it. Disclosures buried after “more”, hidden among twenty hashtags or written in a language the audience doesn’t read fail that test everywhere.

The differences are in the details. Which words, where they go, how far platform tools carry you.

United States: the FTC

The FTC is pragmatic. Disclosures should be hard to miss and placed with the endorsement itself, not only on a profile page, at the end of a post or behind a “more” click. Terms like “advertisement”, “ad” and “sponsored” are fine. The hashtags “#ad” or “#sponsored” are acceptable but not mandatory; a plain sentence such as “Thanks to Acme for the free product” works if it is easy to notice. Vague terms such as “sp”, “spon” or “collab”, or a standalone “thanks”, are not enough.

On platform tools the FTC is cautious: don’t assume they are sufficient, and use them in addition to your own clear disclosure. For video, the disclosure belongs in the video itself, ideally both spoken and shown on screen, and live streams should repeat it so latecomers see it. On Stories and images, superimpose it on the picture with enough time to read. The disclosure should be in the same language as the endorsement.

United Kingdom: ASA and CAP

The UK’s Advertising Standards Authority and the Committee of Advertising Practice publish a dedicated influencer guide. Established practice is a clear, prominent label such as “Ad” or “#ad” upfront, visible without clicking or expanding the caption. Whether a platform’s own label is enough on its own depends on how visible it is in practice; adding “Ad” yourself removes the doubt and costs nothing. The ASA notes that its guide remains broadly correct after the Digital Markets, Competition and Consumers Act 2024, with some changes to the legal underpinning.

Germany: the strictest wording

Germany’s legal basis is § 5a(4) of the Unfair Competition Act: failing to make the commercial purpose of a post recognisable is unfair unless it is obvious from the context. When someone posts about another company’s product, a commercial purpose exists if they receive payment or similar consideration, and that is presumed unless they can credibly show otherwise. The Digital Services Act implementation (§ 6 DDG) and the Interstate Media Treaty add their own transparency duties.

The German media regulators’ guide on advertising labels in online media gets very concrete. Almost pedantic:

• "Werbung" or "Anzeige" as the first word of the caption, or "bezahlte Werbepartnerschaft" in front
• Visible without scrolling or expanding, in the app and in browsers
• Image-only posts: a clearly visible label in the image
• Every Story slide with promotional content labelled individually
• Video where the product is the focus: permanent "Werbung" overlay
• Discount codes: "Werbung" or "Anzeige" right next to the code
• Affiliate links: asterisk plus an explanation next to the link
• No "just in case" labels on posts without any commercial reason

The striking point for international brands: the guide explicitly rules out abbreviations like “ad” and foreign-language phrases such as “sponsored by” or “PR sample”. It does accept “bezahlte Werbepartnerschaft” as a prefix, which is how Instagram’s paid partnership label reads in the German app, so the platform tool can do the job if it is visible without scrolling. Bavaria’s media regulator shows the label combined with “Anzeige” at the start of the caption as an example of good practice.

How seriously this is taken shows in a 2025 check by the consumer organisation Verbraucherzentrale Bayern. It reviewed the Instagram profiles of 26 influencers with more than 500,000 followers each, found breaches in 23 and sent warning letters to ten. Typical faults: no label at all, “Anzeige” at the very end of the caption, words like “Ad” or “Leihgabe” (loan), and tap tags linking to brand profiles without any label.

Germany’s Federal Court of Justice set the framework in three influencer rulings on 9 September 2021 (I ZR 90/20, I ZR 125/20, I ZR 126/20): paid posts about third-party products must be labelled; without consideration, a post is not automatically advertising, though it can become so if it is excessively promotional. Tap tags alone didn’t make a post promotional; a link to the manufacturer’s website generally does.

Side by side

Criterion	United States	United Kingdom	Germany
"#ad" accepted
Preferred wording	ad, sponsored, plain sentence	Ad, #ad	Werbung, Anzeige
Position	with the endorsement, hard to miss	up front	first word, no scrolling
Platform tool alone enough		partly	partly
Free products count
Disclosure inside video

“Partly” means the tool can suffice if it is clearly visible and, in Germany, uses the required German wording.

What brands should put in every briefing

Brands are not off the hook when a creator gets it wrong. The FTC expects advertisers to tell the people they work with about disclosure duties and to monitor what they post. German law goes a step further: § 8(2) of the Unfair Competition Act extends injunction claims to the owner of a business when employees or agents commit the breach, and whether a creator counts as an agent depends on how the collaboration is set up.

Here is a briefing clause you can adapt, as a starting point for your own legal review:

The partner labels every post created under this agreement clearly as advertising, using the word required in the target market (“Werbung” or “Anzeige” for Germany, “Ad” or “#ad” for the UK and US) as the first word of the caption, and for video with an on-screen label for as long as the product is shown. The platform’s paid partnership feature is enabled in addition.

Add pre-publication approval that explicitly checks the label, a rule that every Story slide is labelled, and music from commercially cleared sources only (see music on Instagram Reels for business). Creators addressing German audiences also need an imprint on their profile, explained in the impressum guide for social media in Germany. Staff who promote your products are a related case, covered in the employee social media policy article.

Over-labelling is a mistake too

After the German rulings many accounts started labelling everything, often with phrases like “unpaid ad because brand mentioned”. German regulators advise against that: labelling posts without any commercial purpose dilutes the label. Tagging friends, places or the photographer is not advertising. And a brand’s own, clearly commercial account does not need to stamp “ad” on its own products.

Brands working with many creators at once can partly automate the pre-publication check with an AI system that reviews drafts for required labels. Still, a person signs off.

Next step: pull your current creator contracts and check whether the disclosure clause names the exact word per market. If it just says “follow applicable law”, rewrite it before the next campaign. The FTC’s own guidance is published as Disclosures 101 for Social Media Influencers.

Questions people ask

Is Instagram's "Paid partnership" label enough?

The FTC advises using platform tools in addition to your own clear disclosure, not instead of it. German regulators accept the prefix "bezahlte Werbepartnerschaft", which is how Instagram's label reads in the German app, alongside "Werbung" and "Anzeige", as long as it is visible without scrolling. Adding your own label removes any doubt.

Do free products count as payment?

Generally yes. In the US any material connection, including free products, has to be disclosed. In Germany, receiving products can count as consideration, and German regulators set a 100 euro threshold only for incidental product placements in videos.

Does a brand have to label posts on its own account?

Usually not, when the account is obviously the brand's own. The duty applies when a third party posts about you in exchange for something, or when a seemingly personal account promotes its owner's products.

Is the brand liable if a creator forgets to disclose?

It can be. The FTC expects advertisers to brief and monitor the people they work with, and German unfair competition law can extend injunction claims to the company that commissioned the post.
