Credit Card Security Code
The Railroad Commission of Texas is accepts Mastercard and Visa credit cards for payment on purchases of documents, fees, and services.
The Card Security Code (CSC) is usually a 3 - or 4 - digit number, which is not part of the credit card number. The CSC is typically printed on the back of a credit card (usually in the signature field).
Visa and Mastercard Users:
Flip your card over and look at the signature box. You should see either the entire 16-digit credit card number or just the last four digits followed by a special 3-digit code. This 3-digit code is your Card Security Code.
The security code is only printed the card and it is not contained in the magnetic stripe information nor does it appear on sales receipts or billing statements - you must have the card in your possession in order to use this code.
Card Security Codes are not raised, so they are not scanned into standard credit card readers. In theory, these numbers are only visible to you. When you give your Card Security Code to a merchant, you assist the merchant in verifying that the order is being placed by you, the card holder.
