ACORD 25 Coverage Requirements for ISNetworld: What Your Certificate Must Show

An expired or incorrect certificate of insurance is the single most common cause of an ISNetworld grade drop. More specifically, it's not usually that the insurance doesn't exist — it's that the COI submitted to ISN has the wrong dates, missing limits, or incorrect holder information.

Getting your ACORD 25 right the first time — and every renewal — requires knowing exactly what ISN's standard minimums are, how to read the form, and what to tell your broker.

Standard ISNetworld Minimum Coverage Limits

The following are the standard minimum coverage requirements for most ISNetworld contractor accounts. Individual clients can set higher requirements on top of these — but these are the baseline minimums that ISN itself applies:

• General Liability: $1,000,000 per occurrence / $2,000,000 aggregate
• Auto Liability: $1,000,000 combined single limit
• Workers' Compensation: Statutory limits (varies by state — no specific dollar amount, but the policy must meet the state-mandated minimum)
• Employers' Liability: $500,000 each accident / $500,000 disease each employee / $500,000 disease policy limit
• Umbrella / Excess Liability: $1,000,000 minimum; some clients require $5,000,000+ for refinery, petrochemical, or high-hazard work

Verify the current minimum requirements in your ISN account under the insurance section — ISN displays the required limits for your account configuration and connected clients.

How to Read an ACORD 25

The ACORD 25 (Certificate of Liability Insurance) is a standardized form. Here are the sections ISN reviewers check:

• Section A — Insured: Must match your company name exactly as registered in ISN. Name mismatches cause rejections.
• Section B — Coverage details: Each policy type is listed with policy number, policy period (effective and expiration dates), and coverage limits. ISN reviewers check every limit against your minimum requirements.
• Occurrence vs. Claims-Made: For General Liability, ISN typically requires an occurrence-based policy. A claims-made policy (which only covers claims filed during the policy period, not incidents during the policy period) is often flagged by ISN reviewers. If your GL is claims-made, check with ISN or your client directly.
• Certificate Holder:Must list ISNetworld with their specific address. Your broker needs to know this address — it is not the same as your client's address.

Common Gaps That Fail ISN Review

These are the specific issues that cause COI rejections in ISN's review process:

• Limits below minimum:If any coverage type shows a limit below ISN's required minimum for your account, the document is rejected outright. Check every line — general liability, auto, employers' liability — not just the ones you think might be close to the minimum.
• Wrong policy period on the certificate:Brokers sometimes send a renewal certificate that shows the new effective date but hasn't been properly updated. Or the certificate reflects last year's policy dates. Either way, if the policy period on the COI doesn't match the active policy, ISN rejects it.
• Missing additional insured endorsement: Some clients require that their company name appear as an additional insured on your policy. This requires a separate endorsement from your insurer — the COI alone is not sufficient. If a client has this requirement set in ISN, a COI without the endorsement will fail for that client.
• Wrong certificate holder name or address:ISNetworld has a specific certificate holder designation. If your broker fills in your primary client's name or a generic "holder of record" instead of the ISNetworld-specific holder information, the document will be flagged.
• Workers' Comp listed as N/A:Some brokers mark WC as N/A if they believe it doesn't apply (sole proprietor, for example). ISN reviewers flag this. If you are exempt from WC in your state, you need a signed waiver or exemption certificate — not just N/A on the COI.

How to Work With Your Broker

Most COI problems come from brokers who are unfamiliar with ISNetworld's specific requirements. When you contact your broker for an ISN certificate, give them specific instructions:

• Request the certificate at least 30 days before your current COI expires in ISN — not day-of. Brokers have processing queues and ISN has a review queue. A 30-day lead time prevents a grace-period gap.
• Provide the specific ISNetworld certificate holder name and address (find this in your ISN account under the insurance section).
• Specify the minimum limits explicitly — do not assume your broker knows ISN's requirements.
• Ask for occurrence-based General Liability coverage, not claims-made, if you have a choice.
• If any client requires additional insured endorsement, provide your broker with the client's exact legal name as it needs to appear on the endorsement.

Client-Specific Coverage Overlays

Your ISN grade can be passing overall but failing with one specific client. This happens when a client sets higher minimum coverage requirements than ISN's standard baseline.

Common client-specific overlay requirements include:

• Umbrella / Excess: $5,000,000+ for refinery or chemical plant work (vs. $1M standard)
• Additional insured endorsement (varies by client)
• Waiver of subrogation on Workers' Comp (some industrial clients require this)
• Higher auto liability limits for contractors operating heavy equipment on-site

Check your client-specific grade breakdowns in ISN, not just your overall grade. A contractor can be an A overall and a D with one client — solely because that client requires a $5M umbrella and the contractor only carries $1M.

How Often to Submit Your COI

• Annually at minimum: At each policy renewal, a new COI must be submitted to ISN reflecting the new policy period.
• Immediately on renewal: Do not wait until after your current certificate expires. Submit the renewal certificate before the old one expires to maintain continuous coverage status in ISN.
• Within 30 days of any policy change: Mid-year policy changes — new endorsements, limit changes, carrier changes — require an updated certificate.

Frequently Asked Questions

What if my coverage limits are below ISN's minimum?

You need to increase your coverage. Contact your broker, explain the ISN minimum requirements, and request an endorsement or policy upgrade to meet the minimums. Your annual premium will increase, but you cannot participate in ISN with sub-minimum limits — ISN reviewers will reject the certificate and your grade will reflect the gap.

What does "additional insured" mean on a COI?

An additional insured designation means another party (your client) has some rights under your insurance policy — typically the ability to make claims related to your work on their behalf. It requires an endorsement added to your policy by your insurer, not just a name listed on the certificate. If a client requires it, your broker must add the actual endorsement.

Why did ISN reject my COI when everything looks right?

Check the reviewer comment in your ISN account — ISN reviewers leave specific rejection notes. Common hidden issues: the policy period end date doesn't match the date on the endorsement page, the description of operations section is blank (some clients require it populated), or the broker used an outdated ACORD 25 form version. Read the rejection note carefully and address the specific issue before resubmitting.
