“Only 3 left” is not a design pattern. It is a factual claim about your inventory, and US law requires you to have a reasonable basis for it before you publish it. The same is true of a countdown timer, a “12 people are viewing this” counter, and a strikethrough price.
That framing changes the conversation entirely. The question is not whether urgency is manipulative, which is a matter of taste. It is whether the specific assertion on the page is true, which is a matter of evidence, and the standard for that evidence was set in 1984 and has never been withdrawn.
There is also a regulatory status here that most published advice gets wrong, so it is worth stating early: the federal cancellation rule everyone wrote about in 2024 was vacated in 2025 and never took effect. What replaced it is not nothing, and the details matter.
The rule that governs all of it
Before any specific practice, one doctrine covers the whole field, and it is stricter than most marketers realise.
The requirement. Advertisers must “have a reasonable basis for advertising claims before they are disseminated.”
The consequence of not having one. “A firm’s failure to possess and rely upon a reasonable basis for objective claims constitutes an unfair and deceptive act or practice in violation of Section 5 of the Federal Trade Commission Act.”
And the timing is the part people miss. “The reasonable basis doctrine requires that firms have substantiation before disseminating a claim.” Not on request. Not if challenged. Before.
With the enforcement position stated plainly. “As a matter of law, firms lacking a reasonable basis before an ad is disseminated violate Section 5 of the FTC Act and are subject to prosecution.”
Which is what makes urgency a factual question. A timer says the offer ends. A stock counter says inventory is low. A viewer count says people are looking. Each is an objective assertion, and each therefore needs to be true before it appears.
And deception has a defined test. A representation “likely to mislead the consumer acting reasonably in the circumstances, to the consumer’s detriment”, where the representation is material, meaning “likely to affect the consumer’s conduct or decision”. Urgency claims are material almost by definition, because their entire purpose is to change the decision.
The FTC catalogued these practices in a staff report, which is guidance rather than binding law, but it tells you precisely what the agency is looking at.
The definition. Dark patterns are “design practices that trick or manipulate users into making choices they would not otherwise have made and that may cause harm.”
The four categories. Design elements that induce false beliefs; that hide or delay disclosure of material information; that lead to unauthorized charges; and that obscure or subvert privacy choices. Urgency and scarcity sit in the first.
And the report names the specific mechanisms. Panelists discussed “countdown timers on offers that are not actually time-limited, claims that an item is almost sold out when there is actually ample supply, and false claims that other people are also currently looking at or have recently purchased the same product.”
The taxonomy is unusually concrete. A “Baseless Countdown Timer” is described as “creating pressure to buy immediately by showing a fake countdown clock that just goes away or resets when it times out.” A “False Low Stock Message” is “saying inventory is low when it isn’t.” A “False Activity Message” is “making false claims about others’ activity on a site or interest in a product.”
Note the word doing the work in every one of them. False. Baseless. When it isn’t. The report is not against timers or stock counters. It is against untrue ones.
And on strikethrough pricing there is an actual regulation, not a report. A former price provides a legitimate basis for comparison if it “is the actual, bona fide price at which the article was offered to the public on a regular basis for a reasonably substantial period of time.” An inflated price “established for the purpose of enabling the subsequent offer of a large reduction” makes the bargain “a false one.”
The most instructive enforcement document on this subject is a state settlement, and its detail is worth reading because it shows exactly how these numbers get generated.
The case. In March 2022 an online travel agency agreed to pay “$2,600,000.00 in disgorgement and costs” to settle a state action over its urgency messaging.
The stock message was arithmetic on the search box. The company “added 1 to the number of tickets the consumer had searched for” and displayed that as remaining supply. “Thus, a consumer searching for one ticket would see a message stating ‘Only 2 tickets left’ at the offered price, while a consumer searching for two tickets would see a message stating ‘Only 3 tickets left’.”
The timer was unconnected to anything. “The time left in the running countdown timer was arbitrary and unrelated to the availability of tickets. Fareportal did not reserve tickets for the consumer while the timer was counting down.” And the offer survived the timer: “the consumer could complete the purchase after the time had expired.”
The hotel occupancy figure was a random number in a band. If check-in was more than 30 days out, the message showed “between 0-40% of available rooms were already reserved”. Under seven days out, “between 81-99%”.
And the viewer count is the detail worth remembering. The number of people supposedly viewing hotels in the area “was the difference between the numerical value of the dollar figure and the numerical value of the cents figure” of an unrelated hotel rate. “For example, if the nightly rate of the fifth hotel returned in the search was $195.63, Fareportal represented to consumers that 132 (195-63=132) people were viewing hotel listings in the area.”
Why this matters beyond the anecdote. None of these required a decision to deceive. Each was a plausible-looking implementation choice made by someone building a feature. That is how most of these claims come into existence, and it is why the substantiation question belongs in the build, not in a later review.
It would be easy to imply a federal enforcement record here. There is not one yet, and the distinction is worth making.
No completed federal action on these practices was found. Searching the record, no concluded FTC matter with a judgment or monetary settlement rests primarily on baseless countdown timers or false low-stock messages.
There is a pending one. In June 2026 the FTC filed suit alleging, among other things, that a subscription app displayed “a 10-minute countdown timer, creating a sense of urgency”, and that a discount wheel offered to hesitating users “consistently offers the largest possible discount, 67% off, and engaging the wheel resets the countdown timer.”
But those are allegations. The case is unresolved and there is no monetary judgment. It should be described that way and no further.
So the accurate summary is this. The FTC has named the practice as deceptive in a staff report, and has now sued over it. State attorneys general have already settled cases over it with money changing hands. That is a different risk profile from a mature federal enforcement record, and it is trending in one direction.
The rule that was vacated, and what actually applies
This is the status correction that matters most, because a great deal of advice published in 2024 and 2025 is now describing a rule that does not exist.
What happened. The FTC’s 2024 negative option rule, widely known as click-to-cancel, was vacated in full by the Eighth Circuit on 8 July 2025, days before its compliance date. The court found the Commission had failed to conduct a required preliminary regulatory analysis, and declined to reach the substantive challenges: “the procedural deficiencies of the Commission’s rulemaking process are fatal here.”
It never took effect. The vacatur reinstated the previous rule, first promulgated in 1973, and the FTC formally recodified that older text in February 2026. The current regulation covers prenotification plans, the old book-club model, and does not reach an ordinary online auto-renewing subscription.
The FTC has started again, and that is all. An advance notice of proposed rulemaking was published in March 2026. An advance notice is not a proposed rule and not a final rule. Do not plan around it as though click-to-cancel is returning on a schedule.
But the underlying statute never went anywhere. For any online negative option transaction, the law still requires clear and conspicuous disclosure of “all material terms of the transaction before obtaining the consumer’s billing information”, “express informed consent” before charging, and “simple mechanisms for a consumer to stop recurring charges.”
And it has teeth. In September 2025, after the rule was vacated, a $2.5 billion settlement was reached over subscription enrolment and cancellation practices, comprising a $1 billion civil penalty and $1.5 billion in consumer redress, brought under that statute and the FTC Act. The vacatur did not disarm anyone.
Meanwhile the state layer got stricter. California’s automatic renewal law, as amended, became operative on 1 July 2025 and requires among other things that an online subscriber be able to cancel online without steps that obstruct or delay it. New York’s provision requires a cancellation mechanism as easy to use as the one used to subscribe, through the same medium. The federal rule died; those obligations did not.
One rule that is in force, and narrower than reported
The fee transparency rule survived. It also applies to two industries, which is easy to miss.
It is in force. The rule on unfair or deceptive fees took effect on 12 May 2025.
Its requirement. A business may not “offer, display, or advertise any price of a covered good or service without clearly and conspicuously disclosing the total price”, and “must disclose the total price more prominently than any other pricing information.”
But “covered good or service” is defined narrowly. It means live-event tickets, or short-term lodging including hotels, motels, inns, short-term rentals and vacation rentals. Nothing else.
So for software, ecommerce and services, drip pricing is not governed by that rule. It is governed by the general prohibition on deception, which is a different standard and a different enforcement path.
Two further fee rules were proposed in 2026 covering rental housing and online food delivery. Both are proposed only, with no effective date. The pattern is sector by sector rather than economy-wide, and describing the existing rule as a general one is the most common error about it.
Open every urgency element on your site and write down, next to each, the fact it asserts and where that fact comes from. A timer needs an offer that genuinely ends. A stock counter needs a stock query. A viewer count needs a viewer count. If the answer is a formula, a random range, or a constant, you have an unsubstantiated objective claim on a page whose purpose is to change a decision. The same audit belongs on the ad creative pointing at that page, which is where our B2B paid acquisition work starts, because the platforms judge an advertisement and its destination against each other.
Then check the two things that most often fail silently. Does the timer reset on reload or on a new session? Does the offer still work after it expires? Either answer tells you the claim was never true.
On strikethrough pricing, keep a record of the period during which the higher price was genuinely offered. A former price is legitimate when it was “the actual, bona fide price at which the article was offered to the public on a regular basis for a reasonably substantial period of time”, and that is a record-keeping question rather than a design one.
And if you sell a subscription, ignore the vacated rule entirely and build to the statute plus the stricter state laws: material terms before you take billing details, real consent, and cancellation that is as easy as signing up.
Not in itself. A timer on an offer that genuinely ends is a true statement. A timer that resets, or that counts down to nothing, is a claim you cannot substantiate, and substantiation must exist before you publish.
Can I show 'only 3 left in stock'?
Yes, if three are left. The FTC's dark patterns report lists false low stock messages among practices that trick or manipulate users, and a state settlement in 2022 penalised a company whose stock message was simply the number searched for, plus one.
Has the FTC fined anyone for fake countdown timers?
No completed federal action resting primarily on that practice was found. The FTC sued over it in 2026 and that case is unresolved. The completed money cases on these practices are state attorney general actions.
Is the click-to-cancel rule in force?
No. The Eighth Circuit vacated it in full on 8 July 2025 on procedural grounds and it never took effect. ROSCA and Section 5 still apply, and state auto-renewal laws are now stricter than federal law on cancellation.
