About this reference

Insurance endorsement forms are the most-misunderstood part of a Certificate of Insurance. Vendors get asked for “CG 20 10 and CG 20 37” without context, brokers add description-only language that doesn’t bind the carrier, and lender insurance schedules pile up requirements that nobody on the accepting side can verify by hand.

This reference is the plain-English version. Each entry covers what the form actually does, when it’s required, and the specific failure modes Bindly’s COI verifier sees in the field. Citations refer to the official ISO, NCCI, or FMCSA publications — we don’t reproduce the form text itself, only what it means.

If you manage vendor COIs or chase property managers / subhaulers for the right endorsements, Bindly Compliance auto-verifies these forms on every certificate we track and surfaces deficiencies in a single dashboard.
