Few things are more frustrating than having a customer who’s waiting to pay but can’t because of some error code, especially when there is a long line of customers behind them.
Or, if you’re running an eCommerce business, error codes could be dramatically lowering your checkout conversion rates — and you may not even know! Staying on top of error codes and diagnosing them quickly is key to running a successful business.
There are a variety of reasons why your POS may fire a decline code, from fraud to incorrect information, and it’s not realistic to memorize all of the codes and what they mean (although printing out a list of credit cards decline codes and hanging it nearby could be useful).
Today, we’re going to cover the invalid transaction, or declined code 12. Here’s everything you need to know about what it is and what to do about it.
Also known as the “invalid transaction” code, a credit card error code 12 is given when the issuing bank does not accept a transaction.
That’s super vague, but it’s true.
The issuing bank is the bank that gave the customer their card, and a declined 12 code is sort of a catch-all for error codes. It doesn’t mean one specific thing, but there are a few common reasons why your POS could be sending it.
Here are a few reasons why you could be getting a credit card code 12:
It could be one or a combination of these that is causing your system to fire an invalid transaction. Double-check that it’s not a user error and go from there.
Decline code situations are always annoying, but follow these steps to resolve them as quickly as possible.
Even if you’re pretty sure it’s their fault, being cordial goes a long way to making this process less frustrating for both parties.
Take two! Most people try this first anyway, but just in case you haven’t!
Take a slow read through the code, expiration date, name, and security code. Ask your customer to repeat it if necessary.
It’s possible the customer moved recently and has accidentally put in the wrong zip code. Ask them politely if there’s another zip code possibility.
If you can’t get the card to work, see if your customer minds switching cards for you.
See if they can pay by cash or check. If that isn’t an option, don’t just say sorry! Ask to take their name or give them a more direct phone line.
Chances are they’ll have to call their bank to figure things out, so you want to get them right back to the front of the checkout line when they’ve figured it out.
The last thing you want to do is lose a big sale to a competitor over a system error.
