Nearly two-thirds of Instagram Stories containing ads aren’t labelled properly. That’s not a guess. It’s from the ASA’s 2024 compliance sweep — the one that prompted contact with over 150 repeat offenders.
Across the Atlantic, the FTC ran 23 major enforcement cases in 2025. Triple the 2022 count. Three beauty brands paid $500,000 each. One influencer with 2 million followers was fined $100,000 for 18 months of undisclosed sponsorships. These aren’t warnings anymore. They’re invoices.
Most guides on influencer disclosure rules cover exactly one jurisdiction. The FTC’s official brochure dates to 2019. Law firm guides cover US rules. The ASA covers UK rules. Nobody published the side-by-side comparison that brands operating in both markets actually need. So that’s what this is.
Influencer Disclosure Rules: FTC vs ASA Side by Side
| FTC (United States) | ASA/CAP + CMA (United Kingdom) | |
|---|---|---|
| Core standard | “Clear and conspicuous” — difficult to miss, easy to understand | “Obviously identifiable as advertising” — immediately obvious, no clicking or scrolling required |
| Acceptable labels | “Ad”, “Sponsored”, “Paid partnership with [Brand]”, “#ad”, “#sponsored” | “Ad”, “Advert”, “Advertising”, “Ad Feature.” Rejects “Sponsored”, “Gifted”, and “Supported by” as ambiguous. |
| Platform tools alone? | No. Must add your own disclosure. | Sometimes — but only if upfront, clear, and prominent. When in doubt, add “Ad.” |
| Penalties | Up to $51,744 per violation. Brand and influencer both liable. | ASA: public naming, compliance sanctions. CMA: up to 10% of global turnover under the DMCC Act 2024. |
| Jurisdiction | Content reasonably expected to reach US consumers | All content accessible in the UK |
The difference that actually matters: the ASA rejects “Sponsored” as a label. The FTC doesn’t. If one campaign spans both markets, default to “Ad.” It’s the only term neither regulator will challenge. For more on building campaigns that hold up, see our influencer campaign design framework.
What Triggers Disclosure Now
Both regulators expanded the scope well past “I got paid to post.” Here’s what’s in play in 2026:
- Free products. Both FTC and ASA/CMA treat gifted items as material connections. The FTC draws the line above $5. The CMA’s official guidance states this applies “no matter how many followers you have.”
- Affiliate links and discount codes. Both jurisdictions classify these as advertising. The ASA’s September 2025 update confirms even a personalised discount code triggers disclosure.
- Own-brand promotion. If you own, co-own, or work for the brand, label your own posts. The CMA is explicit: “Do not rely on your bio, previous posts, or selecting limited audiences.”
- AI-generated content. The FTC’s 2025 guidance now treats AI testimonials, voice clones, and deepfake endorsements the same as paid partnerships. The ASA is expected to issue parallel AI-specific rules later this year.
- Carousels. Disclosure goes on slide one. Not slide five. Both regulators are clear.
UK-specific: the CMA also covers competitions, prize draws, and giveaways. Influencer runs a giveaway for your brand? Label it.
What Enforcement Actually Looks Like
US: FTC enforcement actions rose 40% in 2025-2026. Twenty-three major cases in 2025, triple the 2022 count. Three beauty brands paid $500,000 each in 2024 for non-disclosure. A wellness brand running 50 micro-influencers settled at $150,000 because most creators never disclosed gifted products. The per-violation cap: $51,744. Per post, not per campaign.
UK: The ASA’s compliance monitoring found that nearly two-thirds of Instagram Stories ads had no clear label. Over 150 repeat offenders were contacted. But the larger threat is the CMA. Under the Digital Markets, Competition and Consumers Act 2024 — effective April 2025 — the CMA can fine up to 10% of global turnover for serious consumer-law breaches. For a brand with £50M revenue, that’s £5 million. One penalty, not accumulated.
Brands with documented compliance processes see 34% fewer audience complaints (Influencer Marketing Hub, 2026). Documentation isn’t busywork. It’s cheaper than a fine.
A Compliance Checklist That Works in Both Markets
You don’t need two systems. Here’s one checklist that satisfies both FTC and ASA/CMA requirements:
- Default to “Ad.” Only label accepted by both regulators without caveat. Top of every caption. First seconds of every video. Superimposed on every story frame. Don’t bury it.
- Platform tools are supplements, not substitutes. Instagram’s “Paid Partnership” banner and TikTok’s Branded Content toggle help — but add “Ad” on top. Neither regulator considers platform tools sufficient alone. For platform-specific strategy, see our guide to choosing influencer marketing platforms.
- Disclose on every single post. One campaign-start announcement doesn’t cut it. Bios, profile pages, and previous posts don’t count. Both regulators have ruled on this repeatedly.
- Ban ambiguous terms in your contracts. No “collab.” No “spon.” No “sp.” No “thanks [brand].” No “gifted” unless “Ad” sits next to it. Give every creator a one-page guide with screenshots of acceptable and banned language.
- Spot-check within 24 hours. Audit 20-30% of posts in the first day. Flag non-compliance immediately. Withhold payment until fixed. The wellness brand’s $150,000 settlement? Avoidable with this step.
- Keep records. Screenshots of compliant posts. Signed contracts with disclosure clauses. Approval emails. Training logs. When a regulator sends a letter, this is your answer.
- Don’t skip nano and micro-influencers. Creators under 10K are the highest-risk group — fewer resources, less legal awareness, same rules. A one-page PDF with screenshots of good vs bad disclosures takes ten minutes and prevents five-figure fines.
- AI disclosures are mandatory. AI-generated UGC, voice clones, deepfake endorsements — disclose all of it. The FTC treats undisclosed AI content the same as undisclosed paid partnerships.
Key Takeaways
- The FTC and ASA agree on the principle — disclose material connections — but diverge on labels. “Sponsored” passes FTC review. It fails ASA review. Use “Ad.”
- Enforcement is accelerating. $51,744 per FTC violation. 10% of global turnover under the DMCC Act. These are live numbers, not projections.
- Two-thirds of Instagram Stories ads fail ASA compliance. If you’re not auditing your influencers’ posts, some percentage of your campaign is non-compliant right now.
- One compliance system covers both markets. Default to “Ad.” Write it into contracts. Spot-check within 24 hours. Keep records.
- Document everything. When the regulator sends a letter, brands with screenshots and training records fare better. The 34% fewer complaints stat isn’t a correlation — it’s the gap between having a policy and enforcing it.
