If you’re wondering how do I update my insurance when I add a new NAICS code, start here: notify your broker in writing before work begins, gather your supporting documents, and get written confirmation of any classification changes on your policy. Do not wait for renewal. The notification window matters. Allow three to ten business days for a carrier to process a straightforward NAICS change and issue a formal endorsement or updated declarations page. Allow more time if underwriting review is required.

For government and defense contractors, this is not just a paperwork exercise. A new NAICS code can change how your policy is underwritten, what it covers, and what your Contracting Officer expects to see on your certificate of insurance. Getting it wrong mid-contract can stall payments or put your award at risk.

Key takeaways

  • Notify before work begins: Send written notice to your broker as soon as you know a new NAICS code will be active, not after the work starts.
  • Get written confirmation: An agent’s verbal assurance or a database update is not enough. Request an endorsement or updated declarations page from the carrier.
  • NAICS and NCCI codes are different: A new NAICS code can trigger an NCCI workers’ compensation class code change, which directly affects your premium.
  • Audits are real: If you perform work that was not disclosed, a post-period audit can produce a retroactive premium bill.
  • Your KO may need notice too: FAR 28.302 and contract clause 52.228-5 require that material coverage changes adversely affecting the Government’s interest be reported with written notice.
  • SAM.gov updates don’t notify your insurer: Updating your registration in SAM.gov does not automatically alert your insurance carrier. You must contact your broker directly.

How do I update my insurance when I add a new NAICS code: what actually changes on your policy?

Many contractors assume adding a NAICS code is a simple database update. Sometimes it is. But whether the change stays administrative or triggers a real underwriting review depends entirely on whether the new code represents a materially different business operation.

Record update vs. policy endorsement

If the new NAICS code describes work that is similar to what the carrier already underwrote, the insurer may treat it as a simple record correction. But if the new code represents different work with different hazards or exposures, the carrier will likely issue a mid-term endorsement or require a supplemental application. NAICS is primarily an industry descriptor. Insurers use it alongside their own class codes, so a code change can affect eligibility, exclusions, premiums, and required endorsements.

NAICS codes and NCCI workers’ compensation class codes are not the same thing, and they don’t map one-to-one. A new NAICS code can prompt a reclassification of NCCI codes, which directly affects your premium. Understanding which code controls which part of your policy is essential. The table below clarifies the difference.

Term What it identifies Who uses it Matters most for
NAICS code Your business’s primary economic activity (six-digit) Government agencies, lenders, underwriters Applications, underwriting, eligibility, industry reporting
NCCI/class code The work performed and its insurance risk, by employee or job category Workers’ comp insurers and rating bureaus Workers’ compensation classification and premium
NAIC number The insurance carrier (five-digit company identifier) Regulators, agents, policyholders, compliance systems Verifying the insurer on forms and certificates

When carriers require a full policy rewrite

Some carriers will decline to endorse a new activity and instead require the contractor to find a different policy or carrier. This happens most often when the new NAICS code involves higher-risk work: construction, security services, or overseas operations that fall outside the carrier’s underwriting appetite. If your broker gives you a verbal assurance that you’re covered, that is not enough. Get written confirmation of the carrier’s decision before work begins.

What documents do you need to submit to your insurer?

Underwriters don’t just look at the NAICS number. They look at what you will actually do, who will do it, and how much revenue or payroll it will represent. Coming to your broker with these documents ready speeds up the process considerably.

Operations description and business records

Start with a written description of the work your company will perform under the new code, including who performs it and what percentage of your total payroll or revenue it will represent. Support that description with the new contract or scope of work, relevant licenses and permits, and your updated SAM.gov registration. Keep in mind that updating SAM.gov does not automatically notify your carrier. Those are separate records, and you must contact your broker directly to update your insurance for the NAICS change.

Payroll, revenue, and experience evidence

Include payroll estimates broken down by activity, employee and subcontractor information, resumes showing relevant experience, and any existing certificates or loss runs. These figures matter beyond the application stage. General liability and workers’ comp policies are audited after the policy period ends. If your records are inconsistent with how the work was actually classified, the insurer can produce a retroactive premium bill after the audit.

How does adding a NAICS code affect your premiums and coverage?

A higher-risk classification raises the carrier’s rate. A more accurate, lower-risk classification can reduce it. The financial impact depends on what the new work looks like to an underwriter, not just what the NAICS number says.

Classification changes and audit exposure

Workers’ comp premiums are tied to NCCI class codes, not NAICS codes directly. But a new NAICS code can prompt a reclassification of those underlying codes. For example, a GovCon firm expanding into construction work may see field workers moved from an office-based consulting code into a trade-specific construction classification, with office and clerical staff remaining separately classified under NCCI Code 8810. If the contractor performs work that was never disclosed, a post-period audit can produce a large retroactive charge that covers the full policy year.

New exclusions to watch for

Policies written for one type of work often contain exclusions for other activities. A contractor originally classified as an IT consultant may find that their general liability policy excludes field operations or installation work added under a new NAICS code. New endorsements close those gaps, but they typically cost more and must be in place before the work begins. A certificate of insurance by itself does not reveal what the underlying policy excludes, only the full policy document shows those limitations.

How do I update my insurance when I add a new NAICS code: notifying your broker and Contracting Officer

The sequence here matters. Getting the insurance side right before you show up on a job site protects both your coverage and your contract standing.

Notifying your broker before work begins

Follow these steps in order:

  1. Confirm the correct six-digit NAICS code for the new work.
  2. Send a dated written notice to your broker listing the old and new codes, the effective date, a plain-language description of the new operations, and your estimated payroll or revenue split by activity.
  3. Request written confirmation of any endorsements, classification changes, or updated declarations from the carrier.
  4. Update SAM.gov and any applicable state business records to reflect the change.

Keep copies of everything: the notice, the carrier’s acknowledgment, revised policy documents, and any classification worksheets. These records protect you if an audit or a coverage dispute arises later.

What your Contracting Officer needs to see

FAR 28.302 and contract clause 52.228-5 require that cancellations or material changes adversely affecting the Government’s interest be communicated to the Contracting Officer with written notice. If a new NAICS code triggers a coverage change, your KO may need an updated certificate of insurance or a new compliance review. Providing that proactively, rather than waiting to be asked, protects your standing on the award and signals that you manage your contract obligations seriously.

Why GovCon contractors use a specialized broker for these transitions

The process of updating your insurance when you add a new NAICS code is manageable when you know the steps. The part that trips contractors up is knowing when a change is material, which NCCI codes are affected, and what the Contracting Officer will actually require. That is where the broker relationship matters most.

What a generalist broker may miss

Some generalist brokers lack specific GovCon experience, they may not be familiar with what a Contracting Officer requires, how NAICS codes interact with NCCI class codes in a GovCon context, or how to present a contractor’s risk profile clearly to an underwriter. A broker without that background may treat a NAICS change as a simple record update and miss the endorsements or exclusions that leave the contractor uncovered mid-contract. By the time the gap is discovered, the contractor is already performing work that the policy doesn’t cover.

How Risk Reconnaissance manages the transition

Risk Reconnaissance LLC was built specifically for government and defense contractors. Our team brings military and GovCon operational experience to every engagement, which means we already understand contracting terminology, compliance timelines, and what prime contractors and Contracting Officers expect to see. Risk Reconnaissance communicates with underwriters on behalf of government and defense contractors. Risk Reconnaissance offers insurance programs that scale as a contractor’s NAICS portfolio grows.

Build this into your process, not your to-do list

Knowing how to update your insurance when you add a new NAICS code comes down to four actions: notify your broker in writing before work begins, prepare your documentation, confirm all classification changes in writing, and loop in your Contracting Officer if the contract requires it. Done in that order, the process is straightforward. Done late or out of sequence, it creates the kind of compliance problem that stalls payments and puts awards at risk.

Contractors who treat insurance updates as part of their business development process, not as an afterthought after award, rarely face coverage gaps. Every new NAICS code represents a new line of work. Your insurance program should reflect that before anyone shows up to perform it.

If you’re managing a growing NAICS portfolio and want a broker who already understands the GovCon environment, that is exactly what Risk Reconnaissance LLC was built for. Reach out to our team for a review of where your program stands.

Frequently Asked Questions

How long should we expect the insurer to take to process a NAICS change?

Expect three to ten business days for a straightforward NAICS change to be processed and for the carrier to issue an endorsement or updated declarations page. Allow more time if the carrier requires a full underwriting review before changing coverage or classifications.

Who is responsible for paying any increased premium or endorsement costs when a NAICS change leads to higher rates?

You are responsible for any increased premium or endorsement costs that result from the new classification. If the work is higher risk and triggers reclassification or new endorsements, those costs typically appear on your revised premium or at audit if the work was not disclosed.

Is a broker’s verbal assurance enough to start the new work under the new NAICS code?

No, a broker’s verbal assurance is not sufficient; you must get written confirmation from the carrier in the form of an endorsement or updated declarations page. Verbal promises or a database update do not protect you from coverage gaps or contract compliance issues.

If we update SAM.gov with the new NAICS code, does that notify our insurer?

No, updating SAM.gov does not notify your insurance carrier. You must contact your broker directly and send dated written notice including the old and new codes, effective date, description of operations, and estimated payroll or revenue split.
