What is NAICS Code 541810?
NAICS 541810 is the North American Industry Classification System code for "Advertising Agencies." It covers establishments primarily engaged in creating advertising campaigns and placing advertising in periodicals, newspapers, radio and television, and other media for clients on a contract or fee basis.
If your agency creates advertising campaigns, manages paid media, develops creative assets, or plans and places media buys for clients, 541810 is likely your primary NAICS code for government contracting purposes.
Why NAICS Codes Matter for Government Contracts
The U.S. federal government uses NAICS codes to classify and search for contractors. When a federal agency needs an advertising agency, their contracting officers search SAM.gov for vendors registered under NAICS 541810. If your business isn't registered with that code — or isn't registered in SAM.gov at all — you're invisible to federal buyers.
NAICS codes also determine your eligibility for small business set-asides. The Small Business Administration sets size standards by NAICS code. For 541810, the current SBA size standard is $19 million in average annual receipts over the past three years. If your agency is under that threshold, you qualify as a small business for 541810 contracts — which means access to contracts specifically set aside for small businesses, often with less competition.
Related NAICS Codes for Marketing Agencies
Most marketing and creative agencies should register for multiple relevant NAICS codes. The full set for a full-service marketing agency typically includes:
- 541810 — Advertising Agencies (media planning, campaign development, creative)
- 541820 — Public Relations Agencies
- 541613 — Marketing Consulting Services (strategy, market research)
- 541430 — Graphic Design Services
- 541511 — Custom Computer Programming (web development)
- 541512 — Computer Systems Design Services (UX/digital platforms)
- 512110 — Motion Picture and Video Production
- 519130 — Internet Publishing and Broadcasting (digital/social)
Registering for multiple codes broadens your exposure. A federal agency issuing a web design contract may search 541511 or 541512, not 541810 — even if a marketing agency would be a perfect fit.
How to Register Under NAICS 541810
Federal contracting requires two registrations:
- SAM.gov registration (free) — creates your official federal vendor profile and allows you to bid on federal contracts. Requires a DUNS/UEI number, which you get through SAM.gov itself. Registration takes 1–2 weeks to process.
- SBA Dynamic Small Business Search — optional but recommended; makes your business discoverable by contracting officers specifically looking for small businesses.

Winning 541810 Contracts: What Agencies Look For
Government RFP evaluations for advertising agencies typically score proposals on several criteria:
- Technical approach — your creative strategy, campaign methodology, and how you'll achieve the agency's communication objectives
- Past performance — documented examples of similar campaigns. Government clients prefer to see prior government work, but strong commercial work with measurable results is acceptable
- Key personnel — resumes and qualifications of your proposed team. Government clients evaluate the people, not just the firm
- Price — usually evaluated last, on a best-value basis rather than lowest-price-wins
- Small business status — if the contract is set aside for small businesses, verify your eligibility under the 541810 size standard before bidding
