What Does Credit Card Decline Code 51 Mean?

Credit card decline code 51 is one of the most common decline codes and indicates that the customer’s payment method has insufficient funds to complete the transaction. This code applies to both credit and debit cards as well as to all credit card networks (Visa, Mastercard, Discover, American Express), but the specific reason for the decline varies slightly between the two types.

Insufficient Funds for Credit Cards

When a credit card transaction receives a response code 51, it means the purchase amount exceeds the card’s available credit limit. This can happen even if the card is not maxed out, as factors such as pending transactions, holds, or recent payments can temporarily reduce the available credit.

Insufficient Funds for Debit Cards

For debit card transactions, decline code 51 signifies that the cardholder’s bank account does not have enough money to cover the purchase. The available balance is lower than the transaction amount, so the payment cannot be processed.

Common reasons for insufficient funds declines include:

  • Customer’s account has reached its credit limit or balance
  • Recent payments or deposits have not yet cleared in the customer’s bank account
  • Holds, pending transactions, or activity limits are reducing available funds
  • Unexpected fees or charges have depleted the customer’s credit card balance

How Online Businesses Should Handle Decline Code 51

When a customer’s payment is declined with error code 51, act quickly to save the sale and maintain a positive customer experience. Implement these strategies to turn declines into successful transactions.

Disable Automatic Retries

Turn off automatic retries from your payment gateway immediately after receiving a decline code 51. Continuing to attempt charges on a card with insufficient funds will only result in additional transaction fees without a successful payment.

Communicate with the Customer

Notify the customer about the declined transaction due to insufficient funds through a clear, friendly message. This can be an on-screen popup, email, or text message. Politely request that they try again with a form of payment. Use helpful phrasing like:

“It looks like the card you entered has insufficient funds at the moment. Would you like to complete your purchase with a different card?”

Offer Payment Plan Options

Present the customer with payment plan options to make the purchase more manageable. You can offer installment plans directly through your business or integrate with a third-party service like Klarna or Affirm. Breaking the total amount into smaller, scheduled payments can help the customer afford the purchase even if they are short on funds.

Provide a One-Time Discount

Consider offering a one-time discount to incentivize the customer to complete their purchase. While this may slightly reduce your profit margin, securing the sale is often better than losing it entirely due to the decline. Frame the discount as a special offer to help them afford the product or service they need.

By implementing these strategies, you demonstrate understanding and flexibility to your customers facing temporary financial challenges. This approach not only saves sales but also puts a positive spin on a negative event.

Benefits of Properly Handling Decline Code 51

Implementing a smart process to manage payments declined with code 51 offers significant advantages for your online business. By turning these declines into opportunities, you can improve your bottom line while strengthening relationships with customers and payment partners.

Properly handling decline code 51 helps you save sales that would otherwise be lost. By offering alternative payment methods, installment plans, and targeted discounts, you encourage customers to complete their purchases despite temporary insufficient funds.

Reduce Chargeback Risk

Preventing repeated attempts on cards with insufficient funds lowers your risk of chargebacks. Customers are less likely to dispute transactions when you communicate clearly about the reason for the decline and provide helpful solutions.

This can lead to better terms, lower fees, and a more collaborative relationship. It also indirectly improves your relationship with card issuers and issuing banks.
