Paper Checks
Overview
In our increasingly digital world, paper checks still account for over 25% of non-cash payments. And while we are a digital-first company, we still support paper checks for our clients needing it. Paper check features include:
- Mailed Same Day (if request is made before 1:00PM PST)
- USPS Tracking Details
- FedEx Overnight Mail
- Optional PDF Insert

Verified Bank Account Needed
In order to be able to send checks, you need to have a verified bank account in our system. Please refer to the Add a Bank Account section for instructions about adding a bank account to your Checkbook.io profile.
API Basic
The API reference for sending a Paper Check can be found here. The interactive form allows you to test the API endpoint in our demo environment right from the reference page.
