Okay, so you may be thinking "What is this going to be? Is this another fake thing?" Well it's not. This is information is on how valid credit card numbers are generated. The system of generation is called The Luhn Algorithm, also known as the "Modulus 10" and "Mod 10" formulas.

1. To start off, you first want to figure out which credit card company the card will be for. This matters greatly because different companies start with different numbers.

All typical 16 digit Visa account credit card numbers start with a prefix of 4.

All 16 digit MasterCard account numbers start with a prefix of 5.

All 16 digit Discover account numbers start with a prefix of 6011.

All 15 digit American Express credit card numbers start with a prefix of 37.

2. Now, you want to basically write out enough numbers till you get to 16 digits (Ex: If you use American Express and start with 37, then you need 14 more digits). These numbers can be chosen RANDOMLY.

3. Now, start at the far right (The Luhn Algorithm works from right to left) and at every other digit, double the number and write it underneath. So if your card has 16 digits, start at 16 then double the 15, 13, 11, 9, etc. digits and write them underneath the original numbers.

4. If the new number you wrote is only 1 digit, it will replace the original number. If the new number is 2 digits, you must ADD the numbers of each digit together to get the number you will use. (So if you double 5 it equals 10. Then add 1 and 0 to get 1 as your new number. This 1 will replace the original 5.)

5. Now add all of the numbers together. If answer is divisible by 10 then you have successfully created a valid credit card number. If not, then just change the last digit (the 16th digit, also known as the "Check Digit") so that the number is divisibly by 10.

IF YOU DON'T BELIEVE ME, USE THIS SYSTEM WITH YOUR VALID CREDIT CARD NUMBERS. Just do steps 3 through 5.

EXAMPLE

Visa Credit Card (starts with a 4) and then I'm putting random numbers.

4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 --> Double every other. In this case I'm starting at "8"

8 5 12 7 16 9 0 1 4 3 8 5 12 7 16 9 --> For the numbers with 2 digits. Add the digits together.

8 5 3 7 7 9 0 1 4 3 8 5 3 7 7 9 --> Add the numbers together

8+5+3.....+7+9= 86 -->86 is not divisible by 10, so I'll have to change the last digit to a 3.

Final VALID credit card number is 8537790143853773

+rep/thank if you found this post interesting!

This would be considered "carding" and is highly illegal. Why is trash like this on these forums? If you want a credit card, apply for one yourself instead of f**king over someone else's credit.

This doesn't need to be common knowledge, leave this s**t to lowlife scum.

All you need is the cc# and ccv#, btw.

This is so complecated ..

holy shit just use netTools it does it for you

Dude, thats why I said that its for informational purposes ONLY... Lol. I did this for a school project and was just posting about it to let people know how credit card numbers are generated...

This works!! I tried it with my dad's credit card and the numbers worked out perfectly! Wow, very interesting.... kindof complicated too... but cool!
