Overview

• UK Steam accounts must opt in and add a valid credit card to view mature game store pages and related community hubs, with verification lasting while the card remains on file.
• Valve frames the approach as data‑minimal, using its existing payment system with a zero‑charge validation and no third‑party identity or biometric services.
• Early testing suggests the gate most consistently hides 'Adult Only' sexual‑content pages, while many PEGI 18 listings remain visible without verification.
• Some users report that debit cards may work for verification, though Valve’s guidance specifies credit cards and acceptance appears inconsistent.
• Microsoft is also rolling out UK age checks on Xbox, which are optional now but will be required to use full social features starting in early 2026.
