Check a certificate against your requirements

Upload one COI. We read it — limits, dates, endorsements — and tell you whether it satisfies what you actually require. No account, no card, and the file is never stored.

Upload the certificate

What you require

Leave an amount blank and we won't check it. We check every box you leave on, and say plainly when the certificate doesn't settle the question either way.

What happens to the file. It is read in memory to answer this one question and is not written to disk, not attached to any account, and not kept after the response. We don't ask who you are, and this page sets no cookie of its own.

Got a folder of them? Check up to 25 at once and get the list of who to chase.

What this actually checks

It is the same code that runs inside SubTrack on every certificate a customer has on file. This page just points it at one document and no database.
