Woman owned marketing agency: the four certifications, how to check one, and where certified firms are listed

A woman owned agency can say so, or it can prove it. Here is what each certificate verifies, who accepts it, and the checks a buyer runs before counting the spend.

Published by AI Knows Us · Updated 21 October 2026

A woman owned marketing agency is a firm that is at least 51% owned, controlled and run day to day by one or more women. Any agency can describe itself that way, but if you need the spend to count toward a supplier diversity goal or a federal set-aside, you need a certified one. In the US the certificates buyers ask for come from the Women's Business Enterprise National Council (WBENC), the SBA's Women-Owned Small Business (WOSB) program, and the National Women Business Owners Corporation (NWBOC). Outside the US, WEConnect International certifies women owned businesses in about 60 countries. Ask for the certificate, check who issued it and when it expires, and then judge the agency on its work like any other.

Self described or certified: why the difference matters to a buyer

There are two kinds of buyer behind this search. The first simply prefers to hire a firm led by women and is happy with the agency's own word. The second has a reason to prove it: a corporate supplier diversity target, a government contract reserved for women owned firms, or a client who asks. For the second buyer, "woman owned" on a website is not enough. The firm has to hold a certificate from a body that checked its documents.

Certification bodies do not take the claim on trust. WBENC says its process includes a review of documents on ownership, finance, personnel, management and governance, plus a site visit. WEConnect International describes its certification as "a full verified review, not a self-declaration." That review is what a buyer is relying on when it counts the spend.

The four certifications, side by side

CertificateIssued byWhere it is usedWhat it checks
WBE (Women's Business Enterprise)WBENC, through 14 Regional Partner OrganizationsCorporate supplier diversity programmes, and some states and citiesAt least 51% owned, controlled, operated and managed by women; documents plus a site visit
WOSB and EDWOSBSBA, through SBA Certifications (or an approved third party certifier, then uploaded to SBA)Federal contracts onlySmall business; at least 51% owned and controlled by women who are US citizens; women run daily operations and make long term decisions
WBE (NWBOC)National Women Business Owners CorporationCorporations and government bodies that accept itThat the firm is owned and controlled by a woman
WEConnect International certificationWEConnect InternationalMultinational buyers sourcing outside the USOwnership, management, control and independence; at least 51% women owned

Two details catch buyers out. First, the SBA says plainly that WOSB benefits apply only to federal contracting, not to private sector deals, so a WOSB certificate on its own may not satisfy a corporate programme. Second, WBENC is one of four third party certifiers the SBA approves for the WOSB program, alongside NWBOC, the U.S. Women's Chamber of Commerce and the El Paso Hispanic Chamber of Commerce. Even then, a firm certified by one of them still uploads that certificate and proof of citizenship to SBA Certifications before it can bid on a WOSB set-aside.

If you are buying for a federal agency

Marketing is squarely inside the WOSB program. The SBA's list of eligible industries (effective 1 October 2022, read on 21 October 2026) includes Marketing Consulting Services (NAICS 541613), Advertising Agencies (541810), Public Relations Agencies (541820), Media Buying Agencies (541830) and Marketing Research and Public Opinion Polling (541910), all designated for competition among WOSB participants. Across all industries the list holds 733 eligible codes: 626 open to every WOSB participant and 107 reserved for economically disadvantaged women owned small businesses (EDWOSBs).

The government's goal is to award 5% of federal prime contracting dollars to women owned small businesses each year, according to the SBA. That goal is why contracting officers look for these firms, and why the registration matters before the creative does. Every firm that wants federal work also needs a SAM.gov registration, which is covered step by step in our guide to the government creative agency route and the registration that decides who can be hired.

To find certified firms, use the SBA's Small Business Search (SBS, formerly the Dynamic Small Business Search) at search.certifications.sba.gov. The SBA notes that firms must update their SAM.gov profile each year to keep that profile active, so a firm missing from SBS may simply have let its registration lapse. Ask before you rule it out.

If you are buying for a company

Corporate supplier diversity teams usually ask for the WBENC certificate, because it is the one most large US companies already accept. WBENC says its certification is accepted by major Fortune 500 companies and some states and cities, and that certified firms get access to supplier diversity and procurement teams at the corporations and government bodies that accept it. If your company is a WBENC corporate member, your supplier diversity team is the place to start.

If you buy for a multinational and need an agency in another country, WEConnect International is the body to ask about. It says certified firms are visible to its 180+ member buyers and its community of 22,000+ women owned businesses, and that its certification is open to businesses in 60 countries.

Either way, confirm with your own procurement team which certificates they count before you shortlist. A firm can be genuinely woman owned and still hold the wrong certificate for your programme.

How to check a claim in five minutes

  1. Ask for the certificate itself. A logo on a website is not a certificate. You want the document, with the issuing body and the dates.
  2. Check the issuer matches your need. WOSB for federal set-asides, WBE for most corporate programmes, WEConnect International for buying outside the US.
  3. Check it is current. Certificates are renewed. The SBA requires a program examination every three years for WOSB and EDWOSB firms, and WBENC charges for both new applications and recertification.
  4. Check the legal name. The certified entity should be the same company that will sign your contract and send your invoices, not a sister company or a holding company.
  5. For federal work, check SBS. The firm's WOSB or EDWOSB status should show there against the right NAICS code for your requirement.

Then judge it as an agency

Certification answers who owns the firm. It says nothing about whether the firm is good at your kind of marketing. Many certified agencies are small, senior-led shops, which suits some briefs very well and others less so; the trade-offs are the same ones covered in our comparison of boutique marketing agencies and the large networks. Ask the questions you would ask any agency:

  • Who will actually do the work each week, and how senior are they?
  • Will the ad accounts, analytics and website be registered in your name?
  • What will the monthly report show, and which number will you be judged on?
  • Which clients in your sector can you call as references?
  • What happens to the work, the files and the accounts if you part ways?

Write the scope before you write the shortlist. A certified firm that is the wrong fit is still the wrong fit, and the diversity goal is best served by an engagement that lasts.

Questions about hiring a woman owned marketing agency

What makes a marketing agency woman owned?

Under every certification above, the firm must be at least 51% owned by one or more women, and women must control it and manage its day to day operations. Ownership on paper alone does not qualify.

Is WBENC certification the same as WOSB?

No. WBENC's WBE certificate is mainly used by corporations. WOSB is the SBA program for federal contracts. WBENC is one of the SBA's approved third party certifiers, so a firm can use a WBENC review toward WOSB status, but it still has to upload it to SBA Certifications.

Can a federal contract be set aside for a woman owned marketing agency?

Yes, where the requirement falls under an eligible industry code. Marketing consulting, advertising agencies, public relations and media buying are all on the SBA's current list.

Where can I find certified women owned marketing agencies?

For federal buying, search SBS at search.certifications.sba.gov. For corporate buying, ask your supplier diversity team about WBENC's network. For buying outside the US, contact WEConnect International.

Does certification cost the agency money?

SBA Certifications is free. WBENC and WEConnect International charge a non-refundable fee set by the firm's annual revenue, and WBENC adds a 3% card processing fee for applications paid by credit card from 1 July 2026.

What an assistant says when someone asks for a woman owned agency

Some buyers now start this search by asking ChatGPT or Gemini for "a woman owned marketing agency in Denver" or "a certified WBE agency for healthcare". The assistant answers from what is written about each firm: its own site, the directories and press that mention it, and whether the certification is stated in words the engine can read. A firm that shows its WBENC certificate only as a logo image gives the engine nothing to read, while a firm that states its certification, its issuer and its industry in plain text gives it a sentence to quote. Buyers should still run the five checks above on whoever the assistant suggests. Agencies, for their part, can ask the same question and see whether they appear. AI Knows Us is built for that second check: it asks the assistants the questions buyers ask and shows which businesses they name.
