Credit card decline codes usually aren’t “random.” They’re signals. In 2026, declines are happening more often because fraud controls are tighter, banks are faster to block suspicious activity, and customers are using more digital wallets and newer card types. Common reasons for Visa card declines include insufficient funds, reaching a credit limit, and incorrect entry of card information during checkout. If you want fewer declines (and fewer awkward “uhh… it’s not working” moments), you need:
-
a reliable connection and updated POS hardware,
-
the right checkout prompts (ZIP/AVS when needed),
-
clean payment flows for online and keyed transactions, and
-
a staff playbook that fixes the most common credit card decline codes in under 60 seconds.
A card decline at checkout is the business version of stepping on a LEGO.
It hurts, it’s sudden, and everyone looks at you like you personally invented the problem.
The tricky part is this: most declines aren’t caused by “your machine.” They’re caused by the bank, card network, fraud rules, or the customer’s account status. That’s why understanding credit card decline codes matters so much in 2026.
Because in 2026, declines aren’t just “insufficient funds.” They’re increasingly tied to security controls, digital wallet behavior, card verification, and real-time bank decisioning. If you can interpret credit card decline codes and respond the right way, you’ll save sales, shorten lines, and reduce customer frustration.
Let’s break it down in plain English.
Credit card decline codes are the reason messages returned when a payment attempt is rejected. They can come from:
-
the customer’s issuing bank,
-
the card network,
-
fraud/risk systems,
-
or (less commonly) a technical communication issue.
Some systems show a numeric code (like 05, 51, 54). Others show a short message (“Do Not Honor” or “Invalid Transaction”). Either way, it’s a clue about what to do next.
Why declines are more common (and more confusing) in 2026
Here’s what changed:
Banks are stricter and faster
Banks are using smarter fraud models. That means more “false positives” — legit customers getting blocked because something looks suspicious. Decline codes are issued by the payment processor or the customer’s issuing bank and provide specific reasons for transaction failures, helping merchants understand why a transaction was not authorized.
Engaging with issuers and customers can enhance the checkout experience and reduce the likelihood of transaction declines.
More payments are “tokenized” or wallet-based
Tap-to-pay, Apple Pay, Google Pay, and wearables are everywhere. That’s great for security, but it also changes how transactions are routed and authenticated, especially as more customers expect fast, contactless payments using NFC technology.
More businesses accept payments in more ways
You’re not just taking chip and swipe anymore. You’re taking payments on traditional terminals and newer tools like SoftPOS apps that turn phones into card readers. You’re taking payments:
-
in-store,
-
online,
-
via invoice links,
-
over the phone,
-
at events,
-
sometimes even offline.
Every new acceptance method adds opportunity… and a new way to get declined. Issues with the customer’s card, such as restrictions, expiration, or fraud flags, or incorrect card details like the card number, expiration date, or CVV, can also cause declines—so always verify this information to help ensure successful transactions.
The top credit card decline codes (and what they usually mean)
Not every processor displays the exact same set of credit card decline codes, but these are the most common decline codes merchants run into. Common decline codes are frequently encountered reasons for credit card rejection and serve as a quick reference for merchants. A credit card decline code is a two-digit alphanumeric string that indicates why a transaction was processed unsuccessfully, often issued by the issuing bank, payment processor, or credit card networks. These error codes are used to diagnose and troubleshoot declined transactions, helping merchants interpret and resolve issues efficiently.
Code 05 — “Do Not Honor”
This is the most annoying decline because it’s vague on purpose.
What it usually means:
The bank rejected the transaction but doesn’t want to reveal why (often fraud suspicion).
What to do:
-
Ask the customer to try a different card.
-
Try chip instead of tap, or tap instead of chip
-
If it’s a large ticket, suggest they call their bank quickly to approve the charge.
Code 51 — Insufficient Funds
This one is straightforward.
What it usually means:
Not enough funds available (or the customer hit an account limit).
What to do:
-
Ask for another payment method.
-
Offer split payment (if your POS supports it).
If you’re using Clover, split payments are easy and can save a sale when credit card decline codes like 51 pop up.
Code 54 — Expired Card
Classic.
What it usually means:
Card expiration date has passed (or the customer is using an outdated saved card online).
What to do:
-
Use a different card.
-
If it’s ecommerce, prompt customer to update the stored payment method.
Code 57 — Transaction Not Permitted
This can happen when the card is restricted, or the bank blocks certain transaction types.
What to do:
-
Try a different card.
-
If it’s a keyed transaction, try chip/tap.
-
If it’s online, confirm the billing address and verification settings.
Code 61 — Exceeds Withdrawal/Amount Limit
This usually shows up on large tickets and specifically relates to exceeding the withdrawal limit on a Visa card. Exceeding your withdrawal limit can result in a declined transaction.
What to do:
-
Try a smaller amount (partial payment).
-
Ask customer to call bank for approval or use another card.
Code 62 — Restricted Card
Code 62 can be triggered by a fraud account or account restrictions, and is often linked to fraud controls.
**What to do:**Different payment method. If it’s a regular customer, tell them it may be a bank restriction or a fraud account issue and they may need to contact their issuer.
Code 91 — Issuer or Switch Inoperative
This is one of the most important credit card decline codes to recognize because it often points to a network/communication issue.
**What it usually means:**The issuer can’t be reached (network issue, system hiccup, or routing disruption). Sometimes, this is referred to as ‘issuer system unavailable,’ which indicates a temporary communication error with the payment processor or issuing bank, not a problem with the customer’s account or funds.
What to do:
-
Retry once after a few seconds.
-
Switch connection method (Wi-Fi to Ethernet, or vice versa).
-
If you’re seeing multiple 91 codes across customers, start thinking “system issue,” not “customer issue.”

The “it’s not the customer” declines (merchant-side causes)
Minimizing merchant errors by ensuring proper terminal configuration and staff training can significantly lower the occurrence of credit card declines.
Some credit card decline codes are triggered by your setup, not the customer’s bank balance. For example, the ‘invalid merchant’ error (decline code 03) can occur due to terminal misconfiguration, clerical errors, or incorrect merchant codes, which can prevent transactions from being processed successfully. Proper terminal setup and ongoing staff training are essential to avoid such errors and improve both transaction success rates and customer satisfaction.
1) Weak connectivity or unstable internet
If your connection is unstable, payment requests can time out or fail to route cleanly, and a slow or unreliable checkout experience can quietly cost you sales by driving customers away before the transaction completes—especially when it regularly exceeds the 5-second checkout rule for keeping customers engaged.
If your POS has been acting slow or laggy lately, it’s worth addressing because checkout friction turns into lost sales fast:
https://www.getvms.com/why-is-my-pos-system-running-slow/
2) Outdated POS firmware or app version
POS systems need updates (annoying but true). Old versions can cause issues, and older hardware may not fully support modern contactless POS tap-to-pay experiences. Old versions can cause:
-
reader pairing issues,
-
tap failures,
-
random errors that look like declines.
3) Too many keyed transactions
Keyed transactions are higher risk and get declined more often. ‘Transaction not permitted – terminal’ errors can also occur due to terminal configuration issues, which can cause card processing errors and declines. If you’re doing lots of phone orders or manual entry, consider switching to:
-
invoices,
-
payment links,
-
or secure online checkout.
4) Incorrect AVS/ZIP behavior (especially for keyed/online)
If your system is configured to require ZIP/AVS checks and the entered info doesn’t match, you’ll see declines that customers swear “should work.”
Security and authentication: when the problem is verification
Security and authentication are at the heart of modern payment processing, and they’re a major reason why credit card decline codes appear in 2026. When a transaction fails because of verification issues, it’s often due to mismatched or incorrect payment details—think invalid CVV codes, address verification service (AVS) mismatches, or a wrong PIN entry. In these cases, the payment processor or issuing bank may return specific decline codes, such as code 63 for a security violation or codes indicating “transaction not permitted” due to failed authentication.
If you see these card decline codes, the best move is to ask the customer to double check and re-enter their payment details, including the card number, expiration date, CVV, and billing address. For PIN-based transactions, prompt the customer to verify their PIN or try again. If the issue persists, suggest they contact their bank to confirm their account status and resolve any security flags.
Merchants can also reduce these declines by ensuring their checkout systems prompt for all necessary verification fields and by keeping their payment flows up-to-date with the latest security standards. Implementing tools like tokenization and encryption not only protects sensitive data but also reassures both the payment processor and the issuing bank that your business takes security seriously. By staying vigilant about verification, you’ll see fewer decline codes and more successful transactions.
A 60-second staff playbook for credit card decline codes
When staff don’t know what to do, they either freeze… or they start improvising. Both slow down checkout.
Following a structured troubleshooting process can help reduce failed transactions and ensure a smoother checkout experience.
Here’s a simple script flow that handles most credit card decline codes without drama:
Step 1: Confirm the basics
“Let’s try one more time—chip insert instead of tap.”
(You’d be shocked how many tap declines go through on chip.)
Step 2: Try another method
If you have another card or Apple Pay, that usually works when a bank blocks one card type. Alternatively, you can use a separate card or an alternative payment method to complete the transaction.
Step 3: If it’s a large purchase, acknowledge the bank flag
“Sometimes banks block larger purchases for security. If you want, you can call the number on the back of the card and they can approve it.”
Step 4: Offer split payment
“If you’d like, we can split it across two cards.”
This is a huge save for codes like 51 and 61.
Step 5: If multiple customers are declining, switch into “system check” mode
If more than 2–3 customers in a row get odd declines, stop assuming it’s them. Check:
-
internet stability,
-
reader connection,
-
whether your POS is showing any outage symptoms.
How to reduce declines long-term in 2026
If you want fewer credit card decline codes showing up during your busiest hours, these upgrades pay off. Credit card declines can be reduced by improving payment processing systems, ensuring smoother transactions for both merchants and customers.
Additionally, issues with your merchant processing account—such as misconfiguration or inactivity—can prevent successful payments and may require contacting your provider to confirm proper setup.
Improve the reliability of your network
A flaky network turns payment processing into roulette. Consider:
-
using Ethernet for fixed terminals,
-
having a backup internet option (hotspot or failover),
-
upgrading router placement and Wi-Fi strength.
Standardize batching and settlement habits
This doesn’t directly “cause” declines, but bad operational habits often create confusion around what’s happening with deposits and reconciliation.

Tighten fraud prevention without killing approvals
Fraud tools should reduce risk, not block real customers. If you’re seeing declines on legitimate orders (especially online), your settings might be too strict. Scheduled transactions can also be affected if a card is lost or stolen, so it’s important to handle recurring or scheduled transactions appropriately to prevent fraud or unsuccessful payments.
And if you’re seeing disputes after approvals, this guide helps reduce the “approve now, regret later” problem: https://www.getvms.com/how-to-prevent-chargebacks-in-2025/
Upgrade hardware when it’s clearly holding you back
Old readers can struggle with:
-
contactless reliability,
-
modern card types,
-
speed and stability during peak hours.
If your checkout experience is slow, customers feel it—and you lose sales in ways you’ll never track, especially now that card and digital payments dominate customer preferences in 2026.
Credit card decline codes in ecommerce: what’s different?
Online declines are often caused by verification mismatches or fraud scoring. Customers may also be unable to pay online due to issues with their bank account, incorrect account number, or problems within the payment network, and these challenges are growing as the future of payment processing moves toward fully digital, mobile-first experiences.
Common ecommerce causes:
-
billing address mismatch,
-
CVV failure,
-
high-risk IP/location mismatch,
-
too many retries,
-
velocity rules triggered (multiple orders quickly).
When troubleshooting, always review transaction details to identify and resolve specific online payment issues.
If you sell online, your best defense is:
-
clean checkout design,
-
clear policies,
-
smart fraud settings,
-
and accurate descriptors on statements so customers recognize purchases.

A quick note on customer experience (because declines are emotional)
When a card declines, customers often feel embarrassed or defensive. Your staff’s tone matters.
Just a few examples of common credit card decline code triggers include insufficient funds, invalid information, or system errors, and many of these can snowball into disputes—making it critical to follow best practices for avoiding chargebacks, holds, and merchant account freezes.
Teach one simple rule:
Blame the bank, not the person.
Better: “Sometimes banks block transactions for security—let’s try a different method.”
Worse: “Your card is declined.”
That tiny shift reduces tension and keeps the line moving.
Conclusion: mastering decline codes for smoother sales in 2026
Mastering credit card decline codes is more than just troubleshooting—it’s about creating a seamless payment experience that keeps sales moving and customers happy. By understanding the different decline codes, from insufficient funds to suspected fraud, merchants can quickly identify issues and take the right steps to resolve them. This means fewer lost sales and less frustration at checkout.
To minimize decline codes, it’s smart to offer a range of payment options, including debit cards and digital wallets, so customers always have an alternative if their primary card fails, rather than risking the lost sales and poor perception that come with operating as a cash-only business in today’s market. Automated account updates and robust security measures can also help prevent declines due to expired cards or verification errors, and the same careful evaluation you use when shopping for merchant services and processing solutions will help ensure your setup supports these features effectively. And when issues do arise, working closely with your payment processor and the issuing bank ensures you can resolve problems quickly and keep your payment processing running smoothly, including staying compliant with changing rules like Visa’s updated credit card surcharge limits.
Staying informed about the latest decline codes and best practices is essential as online payments and fraud controls continue to evolve. By making decline management part of your regular operations, you’ll reduce losses, boost customer satisfaction, and keep your business competitive in 2026 and beyond.
