Marketing Agency Naics Code

What exactly does “marketing agency naics code” mean in practice? NAICS codes are six-digit numerical codes used by U.S., Canadian, and Mexican statistical agencies to classify business establishments by industry. For agencies, selecting the correct NAICS code tells governments, corporate buyers, and data platforms what services you provide.

Common NAICS codes used by marketing firms

541810 Advertising Agencies. Best for full-service ad agencies that create, plan, and place advertising across media channels, including digital ad buys and creative production.
541613 Marketing Consulting Services. Best for strategic marketing services: market research, marketing plans, brand strategy, and campaign consulting without ad placement as the primary business.
541430 Graphic Design Services. Best when visual design is the primary offered service.
541511 Custom Computer Programming Services. Use this when web development, apps, or custom integrations are the core revenue driver.
519130 Internet Publishing and Broadcasting and Web Search Portals. Apply when running large-scale content publishing platforms or web portals monetized like media businesses.

Why agencies pick one over another

Revenue focus: Use the code that aligns with the largest revenue source. If 70 percent of revenue is ad buys and media placements, 541810 is appropriate.
Contract language: Government forms and RFPs often require a primary NAICS code. Accurate classification reduces risk of disqualification.
Small business eligibility: SBA (Small Business Administration) and other programs use NAICS to determine size standards. The right code impacts eligibility for set-asides.

Why the NAICS Choice Matters for Digital Marketing Agencies

Choosing the correct NAICS code affects four concrete outcomes: contract eligibility, taxes and reporting, industry benchmarking, and discovery by buyers.

Contract eligibility and bidding

Federal, state, and local procurement systems filter opportunities by NAICS code. If your primary code is 541613 but the RFP lists 541810, you risk being excluded. gov and many state procurement portals, buyers restrict solicitations to certain NAICS codes and size standards.

Taxes and reporting

Some data reports and statistical filings use NAICS codes to classify revenue streams. Loan applications, grant applications, and economic development programs refer to NAICS codes to verify business activity. For example, a small business might qualify for targeted grants only if classified under a specific NAICS code with matching NAICS-based size standard.

Benchmarking and market research

Industry reports and tools like IBISWorld, Statista, and U.S. Census data are organized by NAICS. Accurate coding ensures you can find relevant benchmarks (e.g., average revenue per employee for 541810 vs 541613) and price services using comparable firms. If your code is incorrect, you will compare to irrelevant peers and misprice services.

Discovery and lead platforms

gov, SBA Dynamic Small Business Search, Deltek, and some private marketplaces) pull businesses by NAICS. Choosing the correct code increases the signal-to-noise ratio for the leads you receive.

Real number example

A boutique agency with $600,000 in annual revenue that codes itself as 541613 when 80 percent of revenue is performance ad buys can miss out on 50+ RFPs a year in procurement portals that filter for 541810. That could be $200,000 to $500,000 in missed opportunity depending on local contracts.

Action checklist

Calculate revenue by service line for the last 12 months.
Match the top service line to a NAICS code.
Register primary and up to 5 secondary NAICS codes in SAM.gov or relevant portals.
Revisit code choice every 12 months or when service mix shifts by 20 percent.

How to Choose the Right NAICS Code Step by Step

A practical, replicable process for selecting your marketing agency NAICS code.

Step 1.

Pull a profit and loss statement and break revenue into discrete service lines: creative, ad placement, SEO, content, web development, social management. Calculate percentage of total revenue for each line.

Step 2.

Use the common list provided earlier.

SEO and content strategy: 541613 (Marketing Consulting Services) or 541810 if bundled with ad buys.
Paid search and programmatic ad buying: 541810 (Advertising Agencies).
Web development: 541511 (Custom Computer Programming Services).
Design and creative: 541430 (Graphic Design Services).

Step 3.

Primary should reflect the service that produced the greatest revenue in the last 12 months. Add secondary codes for complementary services that generate meaningful revenue or are core to your offering.

Step 4.

Go to the Small Business Administration (SBA) size standards lookup and check the size standard for your chosen code. Compare your annual receipts or employee count to the standard to confirm small business status if you intend to pursue set-aside contracts.

Step 5.

Key systems:

SAM.gov (System for Award Management) for federal contracting.
State and local procurement registries.
Vendor directories used by target corporates.

Step 6.

Update your capability statement, website metadata, and CRM records to include the selected NAICS codes.

Example case

Agency A: 5 employees, $420,000 annual revenue. Revenue split: 50% ad buying and management, 30% strategy and consulting, 20% web development. Primary code: 541810 (Advertising Agencies).

Secondary codes: 541613 and 541511. After registering, Agency A received 3 RFP invites in the first quarter that had previously been filtered out.

Common selection thresholds to use

If one service accounts for >40 percent of revenue, use that service’s code as primary.
If top two services are within 10 points, consider which service you want to grow and pick that as primary, listing the other as secondary.

When to Update NAICS Codes and How to Handle Multi-Service Agencies

Update NAICS codes when business focus or revenue mix shifts meaningfully.

Revenue trigger: A service moves from less than 30 percent to more than 40 percent of revenue over a rolling 12-month period.
Strategic trigger: You pivot your offering (for example, move from an ad-buying focus to SaaS product sales).
Structural trigger: You spin off a division or acquire a business that changes the primary activity.
Contract trigger: You pursue a government or corporate contract that requires a specific NAICS code for eligibility.

How to handle multi-service agencies

Use primary and secondary codes: Most registration systems allow one primary and multiple secondary NAICS codes. Use this to reflect the full scope.
Segment service lines in your marketing: Tag pages and capability statements with the appropriate NAICS codes to ensure buyers and procurement teams find the right match.
Create capability statements per code: For target buyers, produce short capability statements tailored to 541810, 541613, and 541511 as needed.

Administrative steps to change codes

SAM.gov: Log in and update your NAICS codes in the business profile. Edits may take a few business days to propagate.
State vendor portals: Update each state or municipal portal separately; times vary.
Tax and payment systems: NAICS is not typically a tax code but ensure any reporting forms that reference NACIS are updated.

Timeline example for a pivot from consulting to ad buying (30-90 days)

Days 1-7: Revenue audit and selection of new primary code.
Days 8-21: Update SAM.gov, state registries, and marketing collateral. Submit necessary documents.
Days 22-45: Notify existing clients and partners, update capability statements, and run targeted outreach to procurement officers under the new code.
Days 46-90: Track incoming RFPs and adjust secondary codes if needed.

Action tip: Maintain a versioned document (e.g., “NAICS strategy v1.0”) that logs changes, dates, and rationale. This helps when audit trails are required by buyers or funders.

Forgetting secondary codes

Mistake: Registering only one NAICS code when you provide multiple services. gov and state portals to capture relevant opportunities.

Confusing NAICS with SIC or PSC codes

Mistake: Using outdated Standard Industrial Classification (SIC) codes or Product Service Codes (PSC) interchangeably. Avoid by: Use the NAICS code system for classification and reference SIC/PSC only where specifically requested.

Not updating codes after a pivot or acquisition

Mistake: A pivot to web development left the NAICS listing as 541810 for years. Avoid by: Trigger an internal review when service mix changes by 20 percent or after mergers/acquisitions.

Using a too-broad or overly specific code

Action checklist to avoid mistakes
