Age verification is the legal requirement that websites carrying adult or otherwise age restricted content verify that visitors are adults, using methods stronger than a self declared birthdate, such as document checks, facial age estimation or third party verification services. Laws of this kind have spread rapidly across US states, the UK and the EU.
Why it matters
For adult merchants the payments consequence is as important as the legal one: acquirers and card networks treat age verification compliance as a condition of processing, folding it into content rules like BRAM. A site that ignores a verification law in a covered market is not just risking a regulator’s fine; it is giving its acquirer a documented reason to terminate. Verification adds friction and cost per visitor, which reshapes conversion economics, but the direction of travel is one way, and merchants who built compliant flows early are the ones still processing.
