If your card was declined at checkout or renewal, it's usually a quick fix on your bank's side. Common reasons:
- Insufficient funds or a low card limit.
- 3-D Secure / verification not completed.
- International payments blocked — our processor may route the charge internationally; enable international use.
- Bank fraud protection flagged it as unusual — a quick call to your bank to approve usually resolves it.
- Expired card — check the expiry date.
What to try: confirm the card is active and not expired → ask your bank to approve the WhoIsThis charge → try a different card. Still stuck? Email info@whoisthis.io.
