The final four digits of a credit card number are known as the “check digit.” This digit is used to validate the credit card number, and it is not part of the actual credit card number. However, you may be able to contact the credit card issuer and ask for the full credit card number. 

This blog post will help clarify all the related queries about credit cards; It also elaborates to help you better understand your credit number and how to protect yourself from scammers. So let’s clear things up!

What is a Credit Card?

A credit card is a plastic or metal card that gives the cardholder a line of credit to make purchases or cash advances. A credit card differs from a debit card in a way that the credit card issuer lends the cardholder a certain amount of money, that they must repay with interest.

Credit cards are accepted as a form of payment for goods and services worldwide. There are many different types of credit cards available, each with its benefits and drawbacks. Comparing other credit cards before choosing one is essential to ensure they meet your individual needs.

Credit Card History

When choosing a credit card, your credit history and credit score play a very important role. Credit card history and credit score basically show how well you have handled your credit and money, thus increasing your chances of getting a credit card account or loan.  

If you have a good credit history, you can qualify for a credit card with a low-interest rate and a generous credit limit. However, if you have a poor credit history, you may still be able to qualify for a credit card, but you will likely have to pay a higher interest rate, and your credit limit will be lower. 

When you make on-time payments and keep your balance low, it will represent you as a responsible person. It can also help you qualify for better terms on future loans, such as a mortgage or auto loan. Additionally, missed or late payments can damage your credit score.

Types of Credit Cards

There are many types of credit cards on the market, each with its own set of benefits and drawbacks. Here, we’ll take a look at some of the most popular types of credit cards, so you can make an informed decision about which one is right for you.

Travel Credit Cards

If you’re looking for a credit card that will help you save on travel expenses, a travel credit card is a great option. Travel cards typically offer rewards such as points or miles that can be redeemed for flights, hotels, and other travel-related expenses. They may also come with perks such as free checked baggage or priority boarding. 

Cash Back Credit Cards

A cash-back credit card is a great option if you’re looking to earn rewards on your everyday spending. Cash-back cards typically offer a percentage back on all of your purchases, which can be redeemed for cash or used to offset future travel expenses. Most cash-back cards also come with additional perks such as extended warranty protection and purchase protection. 

Starter Credit Cards

A starter credit card is a great option if you’re just starting out with credit. Starter cards typically have lower credit limits and fewer perks than other types of credit cards, but they can help you build your credit history. If you’re looking to eventually qualify for a rewards card or a cash-back card, a starter card can be a good first step. Just be sure to make all of your payments on time and keep your balance well below your credit limit to avoid damaging your credit score.

Business Credit Cards

If you own a small business, a business credit card can be a great way to earn rewards on your business expenses. Business cards typically offer points or miles that can be redeemed for cash back, travel expenses, or other business-related expenses. They also often come with perks such as extended warranty protection and purchase protection. However, business cards tend to have higher interest rates and annual fees than other types of credit cards, so be sure to read the fine print before you apply.

Co-branded Credit Cards

A co-branded credit card is a great option if you’re looking to earn rewards with a specific brand or retailer. For example, you might get a co-branded card from an airline that offers rewards that can be redeemed for flights on that airline. 

Or you might get a co-branded card from a hotel chain that offers rewards that can be redeemed for stays at any of their properties. Co-branded cards often come with additional perks such as extended warranty protection and purchase protection.

Understanding Your Credit Card Numbers

Your credit card number is your key to credit card spending power. This set of digits allows you to make purchases and access credit. These numbers are coded to identify the network, the issuer, and the account of the cardholder. The purpose of these complex order of numbers on your credit card is to prevent credit card fraud and theft. Let’s have a look at the basics of credit card numbers.

Bank Identification Number [BIN]

From the first six digits on a credit card, the very first digit is known as MII and the rest of the five are referred to as BIN. MII basically stands for Major Industry Identifier. For example, MII 1 represents Airlines, 2 represents Airlines and Financials, and 3 represents Travel and entertainment.  

The next five numbers are known as Bank Identification Numbers (BIN). BIN is used to identify the card issuer and helps merchants verify credit card transactions. 

BIN is also used to prevent fraud and minimize the risks of credit card fraud. BIN can help confirm that your transaction is made through the right bank while online shopping. It can also help you figure out which card to use if you have multiple cards from the same issuer.

If you ever need to contact your bank about your credit card, having the BIN can help get your issue resolved quickly.

Account Number

The account number is the essential part of your credit card number. The long set of digits identifies your specific credit card account. The account number also helps your credit card issuer in tracking your spending and keeping track of your payments.

In addition, this number is always unique. You’ll see the account number listed on your credit card statement. It’s usually printed in full on the first page of the information. The account number can also be found on the back of your credit card, near the signature strip.

Check Digit

The Check Digit is the last digit of your credit card number. It’s used to validate the authenticity of your credit card number. The Check Digit is calculated using a mathematical formula that includes all the other digits in your credit card number. Your credit card number is invalid if the Check Digit doesn’t match.

Here’s how the Check Digit works:

  • First, add all the digits in your credit card number except for the Check Digit. It should add up to a multiple of 10.
  • Next, take that sum and divide it by 10. The remainder of that division is your Check Digit.
  • For example, your credit card number is 4123 4567 8901 2345. The Check Digit would be calculated like this: 4 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 0 + 1 + 2 + 3 = 49
  • Now, if we divide 49 by 10, the answer would be 9. That means our Check Digit is 9.

If you’re ever unsure whether a credit card number is valid, you can always check the Check Digit to be sure.


CVV stands for “Card Verification Value.” It is the 3-4 digit number on the back of your credit card. The CVV is used to verify the original credit card owner, thus helping to prevent credit card fraud.

You may be asked to provide the CVV number to complete the transaction when making an online purchase. It is an extra layer of security to ensure that your credit card information is safe.

If you are ever asked for your CVV number by someone you don’t know and trust, it is probably a scam. Never give out your CVV number to anyone unless you are sure that they are legitimate.

How Is Credit Card Number Generated?

Now that you know what each number in your credit card number means, it’s time to take a closer look at how your credit card number is generated.

Credit card numbers are generated using a process called the Luhn algorithm. This algorithm was developed by IBM scientist Hans Peter Luhn in 1954.

The Luhn algorithm is a simple checksum formula that is used to validate a variety of identification numbers, including credit card numbers. The algorithm is designed to protect against accidental errors, such as transposing digits or forgetting to include a check digit.

The Luhn algorithm is also used by banks to generate new credit card numbers. When you apply for a new credit card, the bank will use the Luhn algorithm to generate a credit card number for you.

Credit Card Numbers vs Account Numbers

When it comes to managing your finances, you may come across different types of numbers associated with your accounts. Two common types of numbers are credit card numbers and account numbers. 

While credit card numbers and account numbers both play important roles in managing your finances, they serve different purposes. Credit card numbers are used primarily for making purchases, while account numbers are used mainly for transfers and other transactions.

So, what’s the difference between a credit card number and an account number? Here’s a closer look:

Credit Card Numbers

A credit card number is a 16-digit code that identifies your credit card and links it to your account with the issuing bank. The first six digits of your credit card number are known as the issuer identification number (IIN), which identifies the financial institution that issued your card.

The next nine digits are your individual account number, and the final digit is a check digit, which helps verify that your credit card number is valid. Credit card numbers are also typically embossed on the front of your credit card so that you can easily read them when making a purchase.

Account Numbers

An account number is a code that identifies your bank account, investment account, or another type of financial account. Account numbers are generally shorter than credit card numbers and are typically eight to 12 digits long.

Your account number is unique to your account and is used to identify it when you make a transaction. For example, if you’re making a bank transfer, you’ll need to provide your account number so that the funds can be routed to the correct place, or set up automatic payments or direct deposits. 

How to Protect Your Credit Card Number?

Protection of your account is necessary to prevent you from scammers. Here is a list of a few steps which will help you to protect your credit card number in a professional way.

Never Share Your Personal Information

It is recommended never to give your credit card number to someone you don’t know or trust. Be very careful if someone emails or calls you asking for your credit card number. Scammers can be persuasive, but remember that giving out your credit card number can lead to fraud and identity theft. Only provide it when necessary and to trusted businesses or individuals. 

Monitor Your Account

Always keep an eye on your credit card statements. Check your credit card statements regularly. It will help you spot any unauthorized transactions quickly. Report any suspicious activity on your credit card immediately. Contact your credit card company directly if you see any charges you don’t recognize. By being vigilant, you can protect yourself from credit card fraud.

Take Care Of Your Receipts

Always take care of your receipts when you purchase something from a store because some stores print your personal information, which is enough for fraudsters to create fake credit cards and use your identity. It is always necessary to tear them into small pieces so that all the information becomes unreadable.

Keep Your Credit Card in a Safe Place

Keeping your credit card in a safe place is one of the best ways to protect your credit card number. If you lose your credit card or it is stolen, it can be used to make unauthorized charges. A good place to keep your credit card is in a wallet or purse that you keep with you at all times. You can also keep your credit card in a safe at home or in a lockbox at work.

Check Credit Card Statements Regularly

Checking your credit card statements on a regular basis is another way to protect your credit card number. By checking your statements, you can catch any unauthorized charges quickly and report them to your credit card company. You should also keep an eye out for any strange or unexpected charges. If you see anything that doesn’t look right, contact your credit card company right away.

Use a Credit Card With a Chip

One of the best ways to protect your credit card number is to use a credit card with a chip. Credit cards with chips are more secure than traditional credit cards because they are much harder to counterfeit. When you use a credit card with a chip, your information is encrypted and can only be read by the card reader. This makes it much more difficult for someone to steal your credit card information.

Don’t Use Credit Card at At-Risk Locations

There are some locations where it is not safe to use your credit card. These locations include ATMs, gas stations, and public Wi-Fi hotspots. When you use your credit card at these locations, your information is more vulnerable to being stolen. If you must use your credit card at one of these locations, be sure to use a secure connection and keep an eye on your statement for any unauthorized charges.

Don’t Give Out Credit Card Number Online

One of the worst things you can do is give out your credit card number online. This includes giving your credit card number to websites that are not secure or to people you don’t know. Always check that the website you’re buying from is secure. You can tell if a website is secured if the URL starts with “HTTPS://” instead of just “HTTP://.” It means the site uses a safe connection to protect your information.

If you give out your credit card number online, it is very easy for someone to steal it and use it to make unauthorized charges. Be sure to only give your credit card number to websites that are secure and to people you trust.


Can I Pay Online without CVV?

It’s not possible to make transactions online without CVV. Many online retailers will require you to enter the CVV code during checkout to prevent fraud. However, some retailers will allow you to pay without CVV. 

In this case, the retailer is taking on a higher risk of fraud, so you may be asked to provide additional information, such as your billing address or photo ID.

How do Criminals Make Fake Credit Cards?

Criminals use various methods to create fake credit cards. They use these fake credit cards for various criminal activities, including identity theft, fraud, and money laundering.

  • One popular method is to purchase stolen or compromised card data from online criminal marketplaces. This data can be used to create physical counterfeit cards or to make fraudulent purchases online.
  • Another standard method is to use skimming devices to capture credit card data from legitimate users. This data can then be encoded onto a blank card and used for criminal purposes.
  • Criminals also sometimes create fake credit cards by altering the information on legitimate cards. For example, they may change the card’s expiry date or name. It can do it by physically altering the card or using counterfeit cards with magnetic stripe overlays.

Can Someone Use my Credit Card with Just the Number and CVV?

The answer is, unfortunately, yes. While the CVV adds an extra layer of security, it is not foolproof. All a determined thief needs are your credit card number, expiration date, and CVV to make unauthorized transactions

It doesn’t mean you should never use your credit card online or over the phone. Just be sure to use trusted sites and companies, and always keep an eye on your statement for any suspicious activity.

Can Someone Get your Credit Card Number from a Receipt?

Yes, it is possible. When you swipe a credit card, the machine reads the magnetic stripe. Then the information is sent to the merchant. The problem is that many of these machines also print out a receipt that includes your credit card number, expiration date, and sometimes even your name.

All someone needs to do is pick up one of these receipts and have all the information they need to make fraudulent transactions on your account. The best thing to do is simply not to throw away your receipts. Instead, shred them or keep them in a secure place where only you can access them.


A credit card provides too much ease to its users, but it has become the threat of becoming a victim of cybercrime. You must understand your credit card numbers and how they are of great importance. It is highly recommended to put an eye on your credit card score and always shred or keep your receipts in a safe place to avoid scammers.
