Dynamic QR codes expire when

Short summary

Dynamic QR codes depend on vendor infrastructure that silently fails when subscriptions lapse, scan caps hit, or platforms shut down—the code image persists but redirects go dead. Static QR codes encode the URL directly and never expire. Before printing QR codes at scale, evaluate vendors by grace periods, scan alerts, custom domains, data portability, and operating history.

• •QR codes don't expire—the redirect servers behind dynamic codes do, turning physical materials into broken links when vendors deactivate accounts
• •Silent failure mode: users see 404 errors but have no way to know the code was deactivated, creating invisible brand damage
• •Static codes eliminate server risk entirely; for dynamic codes, prioritize vendors offering grace periods, custom domains, and export options
