If your AstroCard was declined during a purchase, one of the reasons below usually explains why. Most can be resolved in just a few seconds.

Common reasons for a decline

  • Insufficient balance. Your AstroPay balance must cover the full amount, including any currency conversion or fees.

  • Card is paused or blocked. Check the AstroCard section in the app and resume the card if needed.

  • Incorrect card details. Verify the card number, expiry date, CVV, and billing details on the merchant's page.

  • Wrong payment type. Always select credit at checkout — AstroCard does not support debit-only flows or installment plans.

  • 3D Secure not completed. If a verification prompt was missed or expired, the payment is automatically declined. Make sure push notifications are enabled for the AstroPay app.

  • Merchant or country restriction. Some merchants or regions don't accept AstroCard. Try a different payment method on those sites.

  • Limits exceeded. Per-transaction or daily spending limits depend on your verification level and country.

  • Security hold. Unusual activity may trigger an automatic decline to protect your account.

What to do next

  1. Confirm your balance and card status in the AstroPay app.

  2. Double-check the card details and the payment type selected at checkout.

  3. Make sure push notifications are enabled so 3D Secure prompts arrive on time.

  4. Try the purchase again. If it fails a second time, use a different merchant page or contact the merchant for support.

⚠️ Important: If you suspect your card details have been compromised, pause your AstroCard immediately from the AstroCard section in the app.
