Do not honor: what decline code 05 means and what to do

Do not honor is the card issuer's way of saying no without saying why. When a sale comes back with response code 05, the bank that issued your customer's card has declined it. Visa's developer documentation lists response code 05 as "Do not honor". Your terminal sent the request, your processor passed it along, and the issuer looked at it and said no. It just didn't tell you the reason.

That vagueness is what makes the code frustrating. You can't tell from the code alone whether the card was frozen, the issuer's fraud model flagged the sale, or something else went wrong. This guide covers what the code means, what to do at the counter and online, the retry rules Visa and Mastercard publish, and the other decline messages you'll run into. Rules are current as of October 2026.

What does "do not honor" mean?

It means the issuer declined the authorization request and chose a generic reason code instead of a specific one, such as insufficient funds or an expired card. The decision happens at the customer's bank, not at your processor. Every card sale makes the same round trip: your terminal or gateway sends the request to your processor, the processor routes it through the card network to the issuer, and the answer comes back the same way in a few seconds. Our guide to payment gateways walks through that path step by step.

Visa has been pushing issuers toward clearer answers. Its rules group authorization response codes into four categories and require issuers to send descriptive response codes that identify the reason for a decline. One of those categories, Category 4, is for generic response codes. "Do not honor" is about as generic as a decline gets, but processors don't always pass codes through unchanged, so ask yours how it maps the codes you see.

A single 05 is the issuer's decision about one card. A run of declines across many different cards and banks is something else, and we cover it near the end.

What does "declined 005" mean?

It's the same do not honor decline, written with three digits. Visa's Cybersource gateway, for one, lists issuer response code 005 as "Do not honor" in its developer documentation. So a receipt or gateway report reading "declined 005" carries the same meaning as code 05: the issuer turned the sale down and kept its reason to itself. Handle it the same way, by offering another payment method or asking the customer to call their bank.

Why do card issuers send a do not honor decline?

Issuers don't explain, and the customer's bank won't tell you either. Treat this list as possibilities, not a diagnosis:

• The issuer's fraud checks didn't like the sale: an amount, location, or type of merchant that doesn't fit how the cardholder normally spends.
• The account has a hold, block, or restriction the issuer doesn't want to name.
• The card was recently reported lost, replaced, or reissued.
• The sale hit a spending limit set by the issuer or by the cardholder in their banking app.
• On an online or phone sale, the details the customer gave didn't match what the issuer has on file.
• A temporary problem on the issuer's side.

Notice what's missing from that list: your merchant account. When one customer's card says 05 and the next customer's card goes through, the problem is between that cardholder and their bank. The fix usually comes from the cardholder, not from you.

What should a merchant do after a do not honor decline?

Keep it calm and quick, and give the customer a way to finish the purchase. Here's the routine we'd train staff on.

At the counter

1. Don't run the same card over and over. Repeating it right away rarely changes the answer.
2. Tell the customer, quietly, that their bank declined the card. Don't guess at a reason.
3. Offer to take another card or another way to pay.
4. Suggest they call the number on the back of their card. The bank may be able to clear a block on the spot.
5. If the bank clears it, run the card once more.
6. Never force the sale with an offline approval or an approval code the issuer didn't give you. Visa has a dispute condition, 11.2 Declined Authorization, for sales completed after a decline, so a forced sale is a chargeback waiting to happen. Our guide on how a chargeback works explains what follows.

Picture a furniture store in Phoenix ringing up a $2,800 sectional. The card comes back 05. The salesperson says the bank declined it and offers the customer a minute to call. The bank says the large purchase looked unusual and clears it, and the second attempt goes through. If the bank can't help, the store takes another card for the deposit and holds the order. Either way, nobody argues with the terminal. Clearo's POS terminals read chip, tap, and swipe, so in-person sales don't have to be keyed in.

Online and over the phone

Online, show a plain message such as "Your bank declined this payment. Please try another card or contact your bank." Don't show the raw code, and don't hint at fraud. Limit how many times one session or one card can retry. A checkout that lets a bot try card after card invites card testing, and our online payments include velocity rules that cap repeated attempts.

On the phone, read the card number, expiration date, and billing ZIP code back to the customer before you try again, since a typo can trigger a decline. If the second attempt also comes back 05, ask for another card. A dental office in Raleigh taking a payment over the phone in a virtual terminal would follow the same two-attempt rule. Our medical and dental page covers payment setups for practices.

Can you retry a do not honor decline?

Yes, within limits, and the limits depend on the decline category. Visa doesn't permit any reattempt when a decline falls in its "issuer will never approve" category, according to its rules on declined transaction resubmission. For Category 2 and Category 4 response codes, Visa's merchant business news digest says 15 retries in 30 days are permitted.

Mastercard adds a second signal. A declined Mastercard authorization can carry a merchant advice code, and Mastercard's gateway documentation lists what each one means. Code 03 is "Do not try again", and code 02 is "Cannot approve at this time, try again later."

Fifteen is a ceiling, not a target. For a one-time sale, one retry after the customer has spoken with their bank is plenty. For subscriptions and memberships, our guide to recurring billing lays out a spaced retry schedule that stays well inside the limits and runs stored cards through an account updater. Gyms and studios can find more on failed dues in our guide to gym membership billing.

What are the other common card decline responses?

Most declines tell you more than 05 does. Wording differs by processor, and the numeric codes behind these messages vary between networks and gateways, so go by the message and your processor's documentation.

Two of these deserve extra care. A "pick up" or "stolen" response is the one time to stop completely, because no retry will turn it into a good sale. And a mismatch on an online order isn't always a typo. If an order fails the security code check and then succeeds with a different code a minute later, look at it closely before you ship. Our guide to card-not-present transactions covers AVS and CVV2 checks in detail.

How can you reduce do not honor declines?

You can't control an issuer's decision, but you can give it better information and stop the habits that make declines worse.

1. Dip or tap in person. A chip or contactless read generates a one-time security code for each transaction that can't be reused, and the issuer checks it before approving. Our guide to EMV chip cards explains how that works.
2. Send complete data online. Run AVS and CVV2 on every card-not-present sale, so the issuer has more than a card number to go on.
3. Consider 3-D Secure for higher-risk online orders. EMVCo describes EMV 3-D Secure as a tool that helps issuers and merchants prevent card-not-present fraud, by adding an authentication step with the issuer.
4. Warn customers before big purchases. For a large invoice or a deposit, suggest the customer tell their bank it's coming.
5. Keep stored cards current. Expired and replaced cards cause avoidable declines on subscriptions; account updater services help.
6. Track declines by message every month. If one type keeps climbing, you'll know where to look.

Some declines come from authorization holds as well. A hotel or rental deposit can tie up a debit card's available balance, so the next purchase on the same card gets declined. Our guide to the authorization hold explains how holds work and how to release them quickly.

What if you're seeing a lot of do not honor declines?

Call your processor. One decline is about a customer. Many declines across different cards and different banks, in a short time, point to something else, and you shouldn't try to diagnose it alone.

Two patterns to watch for:

• A sudden burst of online declines, often on small amounts and from many cards. That's a classic sign of card testing, where someone uses your checkout to find which stolen numbers work. Tighten velocity rules, slow down repeated attempts, and tell your processor right away.
• A steady rise in declines on in-person sales. Ask your processor to look at how your transactions are being sent and whether anything in your setup changed.

Declines follow card network rules rather than state law, so these steps apply anywhere in the United States. If your customers mostly pay in person, the terminal itself matters, and Clearo's payment processing comes with a dedicated rep you can call when something looks off.
