## Adding a test user in Production
We can enable any existing Pay user to become a test card user. We recommend the following:
- Create a new user account with an email like `user.name+test-pay@partner.com`.
- Use a real phone number that you have access to for the account.
- Let your Shop Pay dev contact know the email for the account and ask them for test card access.
- Once this is done, you can add test card numbers to your [Shop Pay account](https://shop.app/pay)
