Currently, Mercury only offers one type of check product to all customers: mailed checks that are printed and mailed on a customer’s behalf via the Send Money flow.
How to send a mailed check
You can send a paper check to recipients in the US and US Territories from your Mercury dashboard.
- Click Move Money, then select Send
- Choose or add a recipient, or upload a bill to start
- Select Check as the payment method
- Fill in the required payment details and follow the prompts
-
(Optional) Upload up to 6 pages of attachments in PDF, PNG, or JPG format
- Files must be exactly 8.5" x 11" at 300 DPI
- HTML files will be rendered and paginated automatically
- If you're attaching a PDF form, flatten the file before uploading by using Print > Save as PDF to prevent formatting issues during printing
Delivery time
Checks are mailed via USPS without tracking and typically arrive in 7–10 business days (1-2 days to print, then delivery). The check will remain pending until it’s deposited. If not deposited within 90 days, it will automatically cancel.
Important notes
At this time, Mercury doesn’t support broad availability for checkbooks, and you should not use the routing number or account details printed on mailed Mercury-issued checks for direct deposits or account verification. These checks are generated and mailed on your behalf through the dashboard.
If a vendor asks for a check to verify your account, you can usually provide a bank letter instead. Download one from the Documents & Data page under Bank Letters.
