About Coverstamp
Coverstamp checks the certificates of insurance your subs, vendors and tenants send against your own requirements. Here is what it does and doesn't do, how to reach us and how we check the facts on our pages.
What Coverstamp does
It asks the companies you work with for their certificates, reads each one and checks it against the requirements you set, then follows up on what's missing until each file is complete. For contractors, it also checks each payment against the certificate in effect that day.
Coverstamp opens in early 2027. Until then, this site has free tools and a waiting list.
What it doesn't do
Coverstamp doesn't sell insurance, and it gives no insurance or legal advice. It checks documents against your requirements, and your contracts decide what those are. The free tools on this site give estimates, facts and templates; your carrier and your policy decide what an audit really charges.
How we answer
Email hello@coverstamp.com. A person reads every email and answers within two business days.
How we find and check facts
Each fact on our tool and guide pages comes from a primary source: a carrier's or state fund's own page, a rating bureau, a state insurance department, a court decision or a published policy form. The page links each source and gives the day its facts were checked.
When a source's own page can't be reached, we read its newest copy in the Internet Archive and give that copy's date. We check each page's facts again at least once a year.
Report a mistake
If something on our pages is wrong or out of date, email hello@coverstamp.com with the page and what's wrong. We check it against the source, correct the page and change the date it was checked.
