How to Find and Check Full Credit Card Number

You're looking to find and check your full credit card number, huh? This can be a bit tricky, but don't worry, I've got you covered.

First, you can find your credit card number on your physical credit card, usually on the front or back. It's usually 16 digits long, with the first 6 digits being the card's identification number.

If you're having trouble finding it there, you can also check your credit card statement or online account. Many credit card companies display the full credit card number on these platforms.

Now that you've found your credit card number, it's essential to check it for accuracy. Make sure it matches the number on your physical card, and double-check the expiration date and security code.

To find credit card numbers in documents, you can use regular expressions like \b4[0-9]{12}(?:[0-9]{3})?\b or \b\d{13,16}\b. These patterns will help you identify card numbers with or without spaces and dashes.

You can also use a simpler regular expression like \b(?:\d[-]*?){13,16}\b to find card numbers with spaces or dashes. This is particularly useful when searching a large document server or hard disk full of files.

Our online credit card validator uses the Luhn algorithm to verify credit card numbers. This algorithm is also known as the MOD 10 algorithm and was developed by Hans Peter Luhn. It's a simple yet effective way to check whether a credit card number is valid or not.

You can use regular expressions to find credit card numbers in larger documents. Simply replace the caret and dollar with a word boundary as in \b4[0-9]{12}(?:[0-9]{3})?\b.

Searching a large document server can be sped up with a simpler regular expression, \b\d{13,16}\b, which finds any sequence of 13 to 16 digits.

To find card numbers with spaces or dashes in them, use \b(?:\d[-]*?){13,16}\b, which allows any amount of spaces and dashes anywhere in the number.

Regular expressions like \b(?:\d[-]*?){13,16}\b are really the only way to find card numbers with varying digit groupings, such as Visa and MasterCard's 4-digit groups or Amex and Discover's mixed groupings.

Online validation is a crucial step in ensuring the legitimacy of credit card numbers. Our tool uses robust algorithms to verify the entered credit card number in just a few seconds.

The process involves checking the Major Industry Identifier (MII) which is the first digit of the credit card number, identifying the industry or category of the card issuer. The MII numbers represent various categories such as airlines, banking and finance, and more.

Here is a breakdown of the MII categories:

Our tool also checks the Bank Identification Number (BIN/IIN) which is a six-digit number present at the beginning of a credit card number, uniquely identifying the issuing bank or financial institution.

Credit card numbers are a sequence of 13 to 16 digits, with specific digits at the start that identify the card issuer.

You can use regular expressions to alert customers when they try to use a kind of card you don't accept, or to route orders using different cards to different processors.

The ideal regular expression for validating Visa card numbers is ^4[0-9]{12}(?:[0-9]{3})?$, which ensures the number starts with a 4 and has either 13 or 16 digits.

MasterCard numbers can be validated with the regular expression ^(?:5[1-5][0-9]{2}|222[1-9]|22[3-9][0-9]|2[3-6][0-9]{2}|27[01][0-9]|2720)[0-9]{12}$, which checks for specific patterns of digits at the start of the number.

American Express card numbers can be validated with the regular expression ^3[47][0-9]{13}$, which ensures the number starts with 34 or 37 and has 15 digits.

If you want to check whether the card number looks valid without determining the brand, you can combine the above regular expressions using alternation.

Here's a simplified version of the combined regular expression:

^(?:4[0-9]{12}(?:[0-9]{3})?# Visa

|(?:5[1-5][0-9]{2}# MasterCard

|222[1-9]|22[3-9][0-9]|2[3-6][0-9]{2}|27[01][0-9]|2720)[0-9]{12}

|3[47][0-9]{13}# American Express

|3(?:0[0-5]|[68][0-9])[0-9]{11}# Diners Club

|6(?:011|5[0-9]{2})[0-9]{12}# Discover

|(?:2131|1800|35\d{3})\d{11}# JCB

)$

The first digit of a credit card number, the Major Industry Identifier (MII), identifies the industry or category of the card issuer.

This MII number can represent various categories, including ISO / TC 68 and other industry duties, airlines, finance, and more.

You can use a BIN checker to check the Bank Identification Number (BIN) separately, which is a six-digit number present at the beginning of a credit card number.

The Primary Account Number (PAN) is the series of digits that comprise the credit card number, excluding the MII and BIN.

The last digit of a credit card number, also known as the verification digit, is generated using a mathematical algorithm, such as the Luhn algorithm, to validate the entire credit card number's accuracy.

The Luhn algorithm is used to verify the credit card number, and if it fails, the tool will display "Your credit card is invalid."

Here's a breakdown of the MII categories:

The Luhn Algorithm is a mathematical formula used to validate credit card numbers. It's also known as the MOD 10 algorithm and was developed by Hans Peter Luhn at IBM.

The algorithm works by taking the last digit of the credit card number, doubling every other digit starting from the right, summing up the digits of the products, and then checking if the result matches the check digit.

To understand how it works, let's consider an example: a credit card number 347609692102916. The last digit 6 is the check digit, and the rest of the sequence is 34760969210291. Doubling every other digit gives you 3, 16, 7, 24, 0, 36, 6, 36, 2, 4, 0, 8, 9, 2.

Here's a breakdown of the doubling process:

The digits of the products are 3, 9, 7, 9, 0, 9, 6, 9, 2, 4, 0, 8, 9, 2. Adding them up gives 64, and multiplying by 9 gives 576. The last digit of the result is 6, which matches the check digit 6, indicating a valid credit card number.
