Common Card Declines at Costco and How to Resolve Them

Top Five Reasons for Card Declines at Costco

Note: Error codes may vary by card issuer or network but often follow standard formats (e.g., 51 for insufficient funds, 54 for expired card). Always verify with your bank for exact interpretations.

• Insufficient Funds or Declined Authorization (Error Code: 51)

  The transaction exceeds the available credit limit or account balance. This is the most common decline reason, particularly for debit cards or credit cards with low limits.

  • Immediate Fixes:
    • Retry with a card linked to sufficient funds (e.g., switch from debit to credit or vice versa).
    • For credit cards, request a temporary credit limit increase from your issuer (if eligible).
    • Use Costco’s Costco Anywhere Visa® Card (if applicable), which often has higher limits for Costco purchases.
  • Preventive Measures:
    • Monitor account balances before large purchases (Costco’s online system may authorize holds before finalizing charges).
    • Set up low-balance alerts with your bank to avoid unexpected declines.
    • For recurring membership fees, ensure automatic payments are enabled in your Costco account.
• Fraud Alert or Suspected Unauthorized Activity (Error Code: 53 or 58)

  Costco’s payment gateway or your bank may flag transactions as suspicious, especially for first-time cards, high-value purchases, or transactions outside typical spending patterns.

  • Immediate Fixes:
    • Contact your bank to temporarily lift fraud alerts or confirm the transaction as legitimate.
    • Use a different card (e.g., a secondary credit card or Costco’s proprietary card) if the primary card is blocked.
    • For online purchases, try guest checkout to bypass saved payment profiles that may trigger alerts.
  • Preventive Measures:
    • Add Costco’s domain (costco.com) and phone number (+1-800-950-2273) to your bank’s safe list of trusted merchants.
    • Enable two-factor authentication (2FA) on your Costco account to reduce unauthorized access risks.
    • For business cards, ensure spending limits align with Costco’s typical transaction sizes (e.g., $5,000+ for large orders).
• Expired or Invalid Card (Error Code: 54 or 91)

  Cards with expired dates, incorrect CVV, or mismatched billing addresses are automatically declined. This includes virtual cards or prepaid cards with expired validity.

  • Immediate Fixes:
    • Replace the card with an active, unexpired alternative (e.g., a new Costco Anywhere Visa® Card).
    • Update the CVV and expiration date in Costco’s online account under Payment Methods.
    • For prepaid cards, check the issuer’s website for balance or validity status.
  • Preventive Measures:
    • Set calendar reminders for card expirations (most banks offer auto-renewal for Costco cards).
    • For business accounts, assign a dedicated Costco card to avoid mixing personal/expiring cards.
    • Verify billing address matches the card’s registered address (Costco may decline transactions if addresses differ).
• Network or System Errors (Error Code: 91 or 96)

  Temporary glitches in Costco’s payment processing, card network outages (e.g., Visa/Mastercard), or AVS (Address Verification System) mismatches can cause declines. These are often beyond the customer’s control.

  • Immediate Fixes:
    • Retry the transaction after 15–30 minutes (system errors may resolve quickly).
    • Switch to another payment method (e.g., Costco’s proprietary card, PayPal, or Apple Pay if supported).
    • For AVS failures, ensure the billing address in your Costco account matches the card’s registered address.
  • Preventive Measures:
    • Save multiple payment methods in your Costco account to avoid disruptions.
    • Monitor card network status (e.g., Visa’s Global Service Alerts) for outages.
    • For high-value orders, call Costco Customer Service in advance to confirm payment system stability.
• Card Blocked by Costco’s System (No Error Code)

  Costco may temporarily or permanently block cards due to:

  • Multiple failed transactions (e.g., incorrect PIN/CVV).
  • Policy violations (e.g., using a card not issued in the U.S. for U.S. purchases).
  • Suspicious activity detected by Costco’s fraud team.
  • Immediate Fixes:
    • Check if the card is blocked in Costco’s system (see verification steps below).
    • Contact your bank to confirm the card is active and not flagged.
    • Use a different card or payment method (e.g., Costco’s Costco Anywhere Visa® Card).
  • Preventive Measures:
    • Limit test transactions (e.g., $0 authorization holds) to avoid triggering blocks.
    • For business cards, ensure spending policies comply with Costco’s merchant agreements.
    • Regularly update card details in your Costco account to prevent mismatches.
