Ofcom, the United Kingdom's digital regulator, has launched an investigation into social media platform TikTok regarding the effectiveness of its age verification systems. This probe coincides with the release of Ofcom's first age verification usage report since the implementation of the Online Safety Act last summer, highlighting an "unprecedented scale" of age checks across digital platforms in the UK.

Ofcom's Findings on Age Verification

The regulator's report, released on Wednesday, July 16, 2026, indicates that over 69 million age checks have been completed across 32 platforms in the past year. Ofcom frames these developments as a necessary step in preparation for the country's impending ban on social media usage for teenagers aged 16 and under. The agency stated that these efforts are positioning the UK "at the forefront of global efforts to make online experiences safer for children."

Regarding adult entertainment platforms and online pornography websites, Ofcom's data shows that the top 10 most popular sites in the UK, and the majority of the top 100 porn sites, have implemented age checks. Between July 2025 and January 2026, the proportion of minors asked to prove their age before accessing a particular site increased from 25 percent to 43 percent.

Ofcom noted that among the 8% of online children who attempt to access pornography, the presence of age checks acts as an effective deterrent. Half of these children only reached sites with age checks in place. Furthermore, nearly nine in ten of these children’s visits (87%) to porn sites were for under 30 seconds, with 65% lasting less than 10 seconds.

Dame Melanie Dawes, chief executive of Ofcom, commented on the agency's work, stating that "Age checks are a cornerstone of the U.K.’s online safety laws." She added that "When implemented properly, our evidence shows that age checks are helping to create a safer life online for children in the U.K." However, Dawes also emphasized that "the job is not done, and tech companies need to go further. Too many services have no or inadequate age checks in place, which is not good enough."

TikTok Under Scrutiny

TikTok, a popular video-sharing application frequently utilized by adult industry creators and firms for promotion, is now a focus of Ofcom's enforcement efforts. Search engines such as Google and Bing are also targeted in the new enforcement. Dawes explained that Ofcom has "launched an investigation into whether TikTok’s age checks are effective in preventing children from seeing harmful content on its platform." She also urged search engines to "urgently work with us to solve the problem of children finding porn sites without age checks too easily via their results pages."

The investigation into TikTok specifically examines how the platform assesses if a user is a child and whether its systems are adequate to prevent children from viewing harmful content. A key aspect of Ofcom's probe is TikTok's use of "age inference" technology, which estimates a user's age based on their platform activity, such as videos watched or interactions. Kate Davies, Ofcom’s group director for strategy and research, stated that Ofcom has "serious doubts" about the effectiveness of such tools for checking user ages, noting that "some method of age checks being used by social media are not working well enough." Ofcom requires social media platforms to use "highly effective" methods for age verification.

Dawes concluded by stating, "As the U.K. prepares for further new social media restrictions at 16, the age check landscape is already shifting towards a stronger, whole-of-system approach, which is important to avoid any single point of failure." She also expressed a desire "to see continued innovation from the wider tech industry to strengthen protections for children—including from operating systems and at an app store and device-level.”

A spokesperson for TikTok responded to the investigation, stating that the company "strictly enforces age-appropriate experiences through expert-informed platform rules and advanced age inference technologies, in line with major industry peers." The spokesperson added that TikTok is "confident that we meet our Online Safety Act obligations and will work with Ofcom to demonstrate this."

Implications for the Adult Industry

The increased regulatory focus on age verification, particularly ahead of the UK's social media ban for under-16s, has direct implications for the adult industry. While the report indicates a high rate of age check implementation on adult entertainment sites, the ongoing scrutiny of platforms like TikTok and search engines suggests a broader push for robust age verification across all digital spaces where adult content might be accessible. The emphasis on "highly effective" age check methods could lead to further demands for technological innovation and stricter enforcement, potentially impacting how adult industry creators and firms promote content on mainstream platforms.
