What is certificate of insurance (COI)?

The one-page proof-of-coverage document listing your policies, limits, and effective dates. A certificate informs; it does not itself change coverage — endorsements do that.

Why it matters

The COI is the document that unlocks contracts: clients, landlords, and platforms ask for it as proof you are covered. Same-day certificate turnaround is often the practical difference between winning a job this week and losing it. We issue COIs the same day for active policies.
