 How do I find the payment code?

  • Go to your bank account transaction history online or view your accounts paper statement 

  • Find the unauthorized charge from Coinbase, which should look like the below example:

    • COINBASE.COM/BTC 8889087930 0JK873000043

  • The second grouping of numbers will be the 8-digit payment code you need to use to report.

    • You can ignore the first set of numbers beginning with "888"

    • Note that your payment code will be different than the above example

Tip: This information may not be shown to you on your bank's mobile app. Try signing into your bank account using a desktop computer, refer to your paper statement, or contact a representative of your bank to find the payment code.
