COI and insurance data

Certificate of Insurance Statistics for Construction

No published study measures how many construction certificates of insurance are wrong. The best-sourced audit found that more than 90% of one client's vendors had liability policies that did not meet the contract's insurance requirements, even though every certificate showed full compliance. That is one client in 2015, not an industry rate.

This page lists sourced figures on certificates of insurance, what the law says a certificate is, uninsured vendors, and the cost of construction insurance. Each figure shows its publisher, year, method and limit. Contracts Connected compiled and checked these figures. They are third-party figures, not Contracts Connected customer data.

Most error-rate numbers in circulation have no published method. This page does not cite them as findings. The claim checks show where each one came from and what it does and does not show.

Section A 8 figures

How often certificates are wrong (published audits and vendor data)

These are published audits and vendors' own data. Each one has its limit stated in its card.

More than 90%

One audit of one client's vendors found more than 90% had policies that did not match the contract

In one audit of a single client's vendors, more than 90% had liability policies that did not meet the contract's insurance requirements, even though every certificate showed full compliance.

The limit. This is one client's vendors, in 2015. It is not an industry rate, and it is not a share of certificates failing review. The finding is about the policies behind the certificates.

Model act, 2012

The NCOIL model act says a certificate does not change the coverage

The National Council of Insurance Legislators adopted a Certificates of Insurance Model Act on November 18, 2012 and readopted it in 2017 and 2022. It says a certificate 'does not affirmatively or negatively amend, extend, or alter the coverage' and may not warrant that a policy meets a contract's requirements.

Section E 11 checks

Claim checks: where widely repeated figures came from

These figures are repeated across the web. For each one, we traced where it came from and what it does and does not show. We do not cite any of them as a finding.

9 out of 10

Claim check: "9 out of 10 certificates of insurance are wrong"

The claim as repeated. Versions in use: "9 out of 10 insurance certificates contain material misrepresentations," "IRMI audits found 9 out of 10 certificates failed compliance checks," "an ARMR survey in 2005 found..." and "research shows 90%."

Where it came from. David Dybdahl, American Risk Management Resources Network (ARMR). First write-up: R&R Magazine, July 8, 2015. Then IRMI Expert Commentary, July 17, 2015 (fetched in November 2026). Dybdahl used a roughly 90% figure for restoration general liability policies from 2012 on, and restated it in 2017, April 2021 and August 2021 ("more than 80% of the time").

What it shows. One client's vendor pool: artisan and restoration contractors working under one insurer's master services contract. Phase 1 compared certificates with the contract, and all certificates looked 100% compliant. Phase 2 compared the actual policies with the contract, and more than 90% did not meet the requirements in a material way. The IRMI text reads: "Reading between the lines, 9 out of 10 of the insurance certificates ... contained material misrepresentations."

What it does not show. It is not an industry rate. It is not "90% of certificates fail review." Certificates passed review in phase 1. It is not construction-wide, and not current. Later repeaters moved the date to 2005, credited IRMI as the auditor (IRMI published it), and in one case inverted the finding. A separate "90%" in a 2025 BOMA session write-up is a speaker's estimate with no study.

Verdict. The audit is real, specific and sourced, and it makes a good point: a certificate can look perfect while the policy behind it does not match the contract. It supports a narrow sentence about one client's vendors in 2015. It does not support any claim about all certificates. One careful repeater, an insurance agency's 2025 blog, quotes the "artisan contractor" qualifier and links the source.

Safe wording. "One 2015 audit of a single client's restoration contractors found more than 90% carried policies that did not match the contract, even though every certificate looked compliant."

70%

Claim check: "70% of certificates are non-compliant when first received"

The claim as repeated. "On average, 70% of certificates are non-compliant when they're first received." Variants: "seven out of every ten COIs have been shown to be non-compliant" (Vertikal, 2019), "70% of building contractors are noncompliant" (a 2017 Forbes contributor post), "over 70% ... on construction projects" (2025, credited to "industry data"), and "according to Jones Insurance, 7 out of 10" (2026).

Where it came from. The earliest dated appearance found is a myCOI blog post dated February 10, 2017 (read in November 2026 in an archive.org copy). It gives no source, sample or period. It also says 30% of revised certificates are still not compliant. Two other pages credit the figure to myCOI's founder. It is likely myCOI's own processing experience, but that is an inference.

What it shows. That a COI-tracking vendor has said for nine years that most certificates come in with a problem. Nothing more can be read from it, because no data is published.

What it does not show. No sample, no definition of "non-compliant," no count of certificates, no industry, no year. The unit also changes across repeaters (certificates, contractors, COIs "on construction projects"). One repeater's link to Jones for the same figure does not contain it. The 2015 IRMI article has its own 70% (shown in section A), about policy gaps, with no link found between the two.

Verdict. The number may reflect real experience. It cannot be checked, so it cannot be cited as a finding.

Safe wording. "Vendors often say about 7 in 10 certificates fail on first submission. None has published the data."

Where it came from. Evident's "State of Third-Party Insurance Verification" report, released June 23, 2021, and repeated in its 2022 edition. Read in November 2026 through the Metro Atlanta CEO reprint (the Business Wire release returned 403). Evident's own wording says the report draws on "tens of thousands of verification records."

What it shows. In the records of Evident's enterprise customers, 75% of the third parties did not meet every requirement. The reprint also gives a 25% average rate of verified third parties, 23% of vendors that never responded and at least 1 in 10 that fall out of compliance without telling the customer. The 2022 coverage adds that of the 75% that failed, 25% had no appropriate coverage at all.

What it does not show. It does not say which industries, which requirements or how "meet" is defined. The full report is gated. The 2023 release lists construction among many industries but gives no construction rate. The 75% includes vendors who did not respond, so it mixes "did not answer" with "answered with a gap." It is not a share of certificates containing errors.

Verdict. This is a real dataset from a verification vendor, with a stated source. It supports a sentence about Evident's customer data. It does not support a sentence about construction or about certificate error rates.

Safe wording. "Evident, a verification vendor, reported in 2021 that 75% of its customers' third parties did not meet every insurance requirement."

Method

How we check figures

  1. Find the original publisher. We trace each figure to the organization that first published it, not to a page that repeats it.
  2. Fetch the page. We open the original page or file and read the figure there.
  3. Read the sample and method. We note who was counted, how, and when.
  4. State the limit. We write what the figure does not show, next to the figure.

Every figure on this page was re-read at its original source on 2026-11-03. The date of each check sits in the card's change log.

Questions

Frequently asked questions

What percent of certificates of insurance are wrong?

No published study measures that for construction as a whole. The best-sourced audit found more than 90% of one client's vendors had policies that did not match the contract.

Is it true that 9 out of 10 certificates of insurance are wrong?

It comes from one 2015 audit of one client's vendors. Every certificate looked compliant, but more than 90% of the policies behind them did not match the contract. It is not an industry rate.

Where do the 70% and 75% figures come from?

The earliest 70% source we found is a 2017 myCOI blog post with no sample or method. The 75% is Evident's 2021 figure for its customers' third parties, and it includes vendors that never responded.

Does a certificate of insurance prove a vendor has coverage?

The NCOIL model act says a certificate "does not affirmatively or negatively amend, extend, or alter the coverage" and may not warrant that a policy meets a contract's requirements. States pass their own versions.

How many Texas employers carry workers' compensation?

In a 2022 Texas Department of Insurance survey, 75% of private-sector employers carried workers' compensation. For mining, utilities and construction together, the share that did not carry it was 16%.

Why are some widely repeated figures not cited as findings?

Some, like the 70% claim, have no published sample or method. The 9 out of 10 claim comes from one narrow audit. The claim checks show where each came from.

How do you check a figure?

We find the original publisher, fetch the page, read the sample and method, and state the limit. Each figure on this page was re-read at its original source in November 2026.
