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; make sure international use is enabled.
- Bank fraud protection flagged it — a quick call to approve it usually resolves it.
- Expired card.
Try: confirm the card is active and not expired → ask your bank to approve the WhoIsThis charge → try another card. Still stuck? Email info@whoisthis.io.
