Opening new adcenter/adwords accounts & the cards you use – IMPORTANT

Hey guys,

Just thought I’d share this little bit of information. Some of you probably know this but others might have missed it and continue to wonder why accounts with new cards are getting banned.

Credit cards are all structured to follow specific formats.

Mastercard

Digits 2 & 3, 2-4, 2-5, or 2-6 are the bank number depending on whether digit 2 is a 1, 2, 3 or other.

The digits after the bank number are the account number.

Digit 16 is a check digit.

Visa

Digits 2-6 are the bank number.

Digits 7-12 or 7-15 are the account number.

Digit 13 or 16 is a check digit.

American Express

Digits 3 & 4 are the type and currency.

Digits 5-11 are the account number.

Digits 12-14 are the card number within the account.

Digit 15 is a check digit.
