Certificates of Insurance, Explained

INSURHAUS Β· Jun 22, 2026

A Certificate of Insurance (COI) is a one-page summary that proves you carry insurance and lists your coverages and limits.

Who asks for one? General contractors, landlords, venues, and clients commonly require a COI β€” and often ask to be named as an additional insured β€” before you can work or sign a lease.

How to get one from INSURHAUS Existing commercial clients can request a certificate through our online COI request form. Include the certificate holder's exact legal name and address, and note any additional-insured or waiver-of-subrogation requirements. We typically issue certificates the same business day.
