General-consumer credit cards are commonly known as personal or regular credit cards, and they are available to people of all credit...

Basic credit cards usually come with more lenient approval requirements and are better suited for people who are new to credit. A good basic credit card, for example, is the Capital One Platinum Credit Card (see Rates & Fees).
The features of a basic credit card are usually similar across issuers. Their terms, though, may vary. For example, interest rates and credit limits would depend on the...
Applying for a credit card does hurt your credit score, but your score should only drop a few points and rebound within 3-6 months if you use your credit card responsibly. The longest the hard inquiry from a credit card application can affect your score is 12 months. After that point, it will still be visible on your credit report for another year but will have no influence on your score.
Pretty much any time...

You only need one credit card for good credit because simply having an open credit card account is the most efficient way to build and maintain a good (or even excellent) credit score. But the actual number of credit cards you have doesn’t make up a huge part of your credit score – roughly 5%-10%. The more important factors are your payment history, the total amount of your debts, and the total of your credit limits.

Older applicants may provide shared household income if it’s reasonably accessible to them. Some issuers may accept an Individual Taxpayer Identification Number (ITIN) or...
The minimum salary for a credit card depends on the specific card, but you may be able to get approved for a credit card with an annual salary as low as $10,000 or so. While there is no official minimum salary requirement for a credit card, issuers are still required to ensure that applicants can afford monthly payments. As a result, your chances of approval are better with a higher income.

Credit Card Numbers & Expiration Dates
When you need to provide your credit card information to a business, that usually entails listing your name, card number, expiration date and security code. You can learn more about these credit pieces of information below.
A credit card account number is part of your overall credit card number, beginning at the seventh digit and ending on the second-to-last digit. The length of a credit card account number depends on the card: American Express account numbers are 8 digits, for example, while many other cards have 9-digit account numbers.
Credit card account numbers are similar to checking account numbers, though most people will use their checking account number far more.
...The code on the back of a credit card is a three-digit number known as a Card Security Code (CSC) or Card Verification Value (CVV), among other names. This code is on the back of credit cards because it helps to prevent fraudulent purchases from being made online or over the phone.
You’ll need to provide it whenever you make a so-called “card not present” transaction – such as a purchase from an online...
Yes, a credit card can have 15 digits. American Express credit card numbers have 15 digits, while credit cards affiliated with other major payment networks such as Visa and Mastercard have card numbers that contain 16 digits.
Each digit on a credit card has a specific meaning, whether it’s 15 or 16 digits. To learn more about what these digits stand for, refer to WalletHub’s credit card number guide.
A CVV number is a 3-digit or 4-digit security code that’s used to prevent fraudulent charges on credit cards and debit cards. You can find the CVV, or card verification value, on the back of most cards, though American Express cards have their CVV located on the front.
When You Need Your CVV Number
You will need to provide a CVV number anytime you make a “card not present” purchase. These are transactions in which you are...
Both CCV and CVV are correct, as they refer to the same security feature: a three or four-digit number printed on the card, that is required during card-not-present transactions. CVV is the term that’s more commonly used out of the two.
Regardless of the terminology used, the security code serves the same purpose across all cards, which is to add an extra layer of security. When making an online or over-the-phone transaction, the code is used to verify that the person...
A CVV is usually three digits, but it can be four digits on some cards. Visa, Mastercard, and Discover cards all use a three-digit CVV, while American Express is the exception that uses a four-digit CVV on its credit cards.
The CVV is required anytime you cannot provide a merchant with a physical card, such as an online or phone purchase. This security code is necessary because it allows the merchant to confirm that...
Credit cards starting with 4 mean they are on the Visa network. They can be used for purchases at more than 10 million merchants in the U.S. and in 200+ countries and territories. A credit card starting with 4 also gives you access to Visa’s standard benefits, including fraud liability protection. Individual card issuers may elect to provide additional Visa perks for certain types of accounts, too.
The first digit in a card number isn’t...
Mastercard credit cards start with the number 5. That means all credit cards beginning with 5 can be used at the 110+ million merchants in more than 210 countries that accept cards on the Mastercard network. A credit card starting with 5 also gets you access to certain peripheral perks such as extended warranties and fraud liability protection, though some Mastercard credit cards have better benefits than others.
One thing that credit cards starting with 5 do not share, however,...

Examples for Credit Cards That Start With 7

How Numberless Cards Work
Instead of displaying the card number, expiration date, and CVV on the card's surface, these details are stored digitally. You can access the card information through the...
The number under the magnetic stripe on a credit card is typically the CVV (Card Verification Value) or security code. On most cards, like Visa and Mastercard, this three-digit CVV is printed on the back of the card, under the magnetic stripe. It's used as an extra layer of security for online or over-the-phone transactions to verify that the cardholder has the physical card.
However, for American Express cards, the CVV is a four-digit code...
A Visa credit card starts with 4147, judging from the first digit of this string of numbers. Each credit card has a unique string of numbers, but the first one can help you identify the payment network. When combined with the first digit, the next 5 digits identify the credit card issuer. So, depending on the 2 digits that follow this number, the card could be issued by either Chase or Capital One, among other issuers.

To tell the type of credit card by the number, simply look at the first digit of the credit card number, either on the front or back of your card. The first digit of an American Express card is 3, while it’s 4 for Visa cards, 5 for Mastercards, and 6 for Discover cards.
Most credit card numbers will contain a total of either 15 or 16 digits. American Express credit cards contain 15....
Visa credit card numbers start with the number 4. Each credit card has a unique string of numbers, but the first one or two digits can help you identify the payment network. For example, Mastercard’s first digit is the number 5 and American Express card numbers start with 3.
When combined with the first digit, the next 5 digits of a credit card number identify the card issuer for any given Visa. The subsequent 8 numbers are part of...
No, all Visa cards don’t start with the same 4 numbers. However, they do have the same first digit, which is always the number “4.” In fact, each card has a unique string of numbers, but the first digit can help you identify the payment network.
The next 5 digits indicate the bank that issued the card. The 7th digit through the second to last is the cardholder’s personal account number. The last digit of each Visa card’s number...
A Visa card number is the 16-digit number on a Visa credit card, debit card or gift card. The first digit of a Visa card number is always 4. The next 5 digits after that indicate the bank that issued the card. The 7th digit through the second to last is the cardholder’s personal account number. The last digit of each Visa card’s number is a security measure for verification purposes.
The Visa card number is typically embossed on the front of...
Your Visa card number and security code help verify the card’s authenticity. You need them, along with the card’s expiration date, to make purchases online or over the phone. Luckily, your Visa card number and security code are easy to distinguish once you know what you’re looking for.
How Visa card numbers and security codes work:
- Card number: A Visa credit card number can be 13-to-19 digits long. It’s usually printed right on the...
A credit card typically expires three to five years after it is issued, but the exact length of time depends on the issuer. The expiration date on a card will show a month and a year, and the card expires on the last day of the month.
Key Facts About Credit Card Expiration
- Security Reasons: Credit card expiration helps ensure the card’s security, allowing the issuer to regularly update the card with...
No, not all credit cards expire every 4 years. The expiration date of a credit card varies depending on the issuer, and typically falls within a 3-5 years period from the date that the card was issued. Your credit card's specific expiration date should be located on the front of the card, below the 15 or 16-digit number.
Having an expiration date on a credit card serves as a security feature because it gives payment processors one...
A credit card expires at the end of the month written on the card, not the beginning. You’ll find your credit card’s expiration date on the bottom half of your card, below your card number, in a month/year format. The date is usually about three years in the future. So if you have a card that expires in November 2020, you’ll be able to use it all the way through the last minute of the last day in...
No, you can’t use your credit card if it has expired. If you try to use it in stores or for online transactions, the card will be declined. Typically, you should receive a replacement a few weeks before your current card's expiration date. If you haven’t received the new card yet, it's possible that the card got misplaced or stolen and you need to contact your issuer.
Keep in mind that, even if your...
No, a credit card cannot expire if you won't activate it, but it will most likely be disabled. If you don't activate a credit card and thus don't use the card, your account may be closed. Card issuers typically close accounts that aren't used within a certain time period, usually over a year.
Keep in mind that your account could be closed without notice, and it could have a negative impact on your credit...

Chip-and-PIN credit cards are more secure than chip-and-signature credit cards because it’s harder for someone to guess your PIN than to forge a signature.
Just note that chip cards are not completely secure. Chip credit cards still have a magnetic stripe, so the info from the magnetic...
