## Surcharging in test mode

We've added test credit cards so you can test surcharge fees in test mode. When testing surcharge fees, use the following cards and accompanying requirements:

| Card brand          | Test card number        | CVV            | Postal code     | Expiration date   |
|--------------------|-------------------------|----------------|------------------|--------------------|
| Visa               | `4111300030003000`     | Any 3 numbers  | Any 5 numbers    | Any future date    |
| Mastercard         | `5200900090009000`     | Any 3 numbers  | Any 5 numbers    | Any future date    |
| Discover           | `6011111111111117`     | Any 3 numbers  | Any 5 numbers    | Any future date    |
| American Express    | `371111111111114`      | Any 4 numbers  | Any 5 numbers    | Any future date    |

The test credit cards above can be used for testing any features in test mode. Additionally, we've added two new test debit cards:

| Card brand          | Test card number        | CVV            | Postal code     | Expiration date   |
|---------------------|-------------------------|----------------|------------------|--------------------|
| Discover            | `6011233333330000`     | Any 3 numbers  | Any 5 numbers    | Any future date    |
| American Express    | `372021002000199`      | Any 4 numbers  | Any 5 numbers    | Any future date    |
