Many credit card issuers no longer require you to sign the back of your card. But if there’s a space on your credit card for a signature, then it may still be a good idea to sign it.
Read on to learn about the importance of signatures on credit cards historically and why they matter today. You can also check out some modern-day tips for protecting yourself against fraud beyond signature verifications.
What you’ll learn:
There was a time when signing your credit card was an important step in helping prevent credit card fraud. When you paid with your credit card, the merchant would compare your signature on the receipt with the one on your card. If they matched, the merchant would approve the transaction.
These days, credit card purchases are securely authenticated electronically. For many transactions—like those made online, with an EMV chip reader or by tapping your phone—merchants never even see your card at all. So when it comes to preventing fraud, signing your card isn’t as important as it used to be.
Even though signatures aren’t used the way they once were, it may still be a good idea to sign the back of your credit card if it has a signature panel. Here’s why:
The practice of writing “See ID” in a credit card’s signature panel stems from the older security measure of matching signatures. People used to write “See ID” to prompt a merchant to compare the cardholder’s signature on the receipt with the one on the cardholder’s ID before authorizing the sale. In theory, this would reduce the chances of credit card fraud.
But while this may have been more common at one point, writing “See ID” on your credit card isn’t typically recommended.
For starters, signatures aren’t always required for credit card purchases under a certain amount. Merchant agreements might even prohibit a retailer from requiring a cardholder to present their ID in order to approve a sale.
If your issuer requires you to sign your credit card, your card might still be considered inactive and invalid if you write “See ID” in place of your signature. You can check your credit card agreement or check with your issuer to see whether writing “See ID” is OK.
Some credit cards come with built-in security features and benefits designed to help protect against fraud. And those safeguards may go beyond basics like your personal identification number, or PIN, and card verification value number, or CVV number.
Capital One’s credit cards, for example, may have available features like instant purchase notifications, fraud alerts, $0 liability for unauthorized charges, card lock and Eno, your Capital One assistant. 1, 2, 3 Eno can even create virtual card numbers to keep your actual card number under wraps when you check out online. 4

Here are the answers to some questions commonly asked about signing credit cards:
Where do I sign my credit card?
You’ll often find a blank white box on the back of your credit card. This is where you can sign your card.
Can I leave the back of my card blank?
Not all credit card issuers require you to sign your card. If that’s the case with your issuer, you could choose to leave the back of your card blank. Leaving your credit card’s signature panel blank isn’t going to stop the card from working. But you could run the risk of having a transaction denied on the off chance that a merchant requires or prefers the signature.
What if there’s no place to sign the back of my credit card?
If your issuer doesn’t require you to sign your card, your credit card might not feature a signature box at all. So if you don’t see a signature panel, then you most likely don’t need to sign. You can call your credit card issuer to check if you’re unsure.
Should I sign my credit card with a pen?
Black or blue felt-tipped pens are typically recommended for signing credit cards. Ballpoint pens may look faint or scratch the plastic.
You can check with your credit card issuer to see if you’re required to sign your credit card. But it’s generally recommended to go ahead and sign it if there’s space on your card for a signature. That way, you’ll be covered if a merchant requires the signature for a purchase.

5 Your CreditWise score is calculated using the TransUnion® VantageScore® 3.0 model, which is one of many credit scoring models. Your CreditWise score can be a good measure of your overall credit health, but it is not likely to be the same score used by creditors. The availability of the CreditWise tool depends on our ability to obtain your credit history from TransUnion. Some monitoring and alerts may not be available to you if the information you enter at enrollment does not match the information in your credit file at (or you do not have a file at) one or more consumer reporting agencies.
CreditWise Alerts are based on changes to your TransUnion and Experian® credit reports and information we find on the dark web.
