Mercury doesn't currently offer physical checkbooks, but you can have a paper check mailed directly from your dashboard. 

Here's how to do it:

1. Log in to your Mercury dashboard.
2. Click Move Money in the upper left of your dashboard, then select Pay Someone.
3. When asked How do you want to pay?, select Check.
4. Follow the prompts on screen to finish setting up your payment.

Checks usually take about 7-10 days to mail. 

Need a voided check to verify your account? You can usually send a bank letter instead, which you can download on your dashboard.
