Certificate Of Insurance Extraction
Does the vendor actually have the coverage the contract requires? The COI knows — if someone reads it.
Certificate of insurance (COI) extraction is the automated reading of the standardized-but-not-quite documents that evidence insurance coverage: insured and producer details, policy numbers and carriers, coverage types (general liability, auto, workers' compensation, umbrella), limits per occurrence and aggregate, effective and expiration dates, additional-insured and waiver-of-subrogation indications, and the description-of-operations text where crucial qualifications hide. Any organization that requires proof of insurance from vendors, subcontractors, tenants, or event participants accumulates COIs by the thousand — and unread COIs are unverified risk.
The ACORD 25 form gives the domain a deceptive appearance of standardization: the layout is common, but certificates arrive as faxes, scans, and photos of varying quality; carriers and brokers customize; limits appear with inconsistent formatting; checkbox semantics matter (that small "X" in the additional-insured column changes legal position); and the free-text operations description routinely overrides what the grid implies. Extraction therefore pairs form-aware field reading with checkbox recognition and language understanding of the descriptive text, feeding validation that normalizes limit amounts and dates.
Extraction is the enabling half of the real objective: compliance verification. Extracted values compare automatically against each vendor's contractual requirements — required coverage present, limits sufficient, dates current, required endorsements indicated — producing a pass, a specific deficiency list ("auto liability limit below required $1M"), or a renewal chase when expiration approaches. At portfolio scale, this converts an intractable filing-cabinet problem into live compliance visibility: which vendors are covered, which have lapsed, and which certificates claim coverage the underlying policy endorsements don't actually support — the latter feeding escalation to human specialists, since a COI is evidence of insurance, not the insurance itself.
Is this actually covered? Answered by reading the policy, not by remembering it.
The insurance policy as it was actually issued — schedule, wording, and endorsements, structured together.
The policy is what the endorsements made it — extracting the amendments that change everything.
