TL;DR
The Women-Owned Small Business (WOSB) Federal Contracting Program lets eligible woman-owned businesses compete for federal set-aside contracts in industries where women-owned firms are underrepresented. To qualify, your business must be at least 51% unconditionally and directly owned and controlled by one or more women who are U.S. citizens, hold the highest officer title, and work full-time in the business. Certification is free through the SBA's portal at certify.sba.gov, or available through four SBA-approved third parties for a fee.
What Is WOSB Certification?
The WOSB Federal Contracting Program is administered by the U.S. Small Business Administration. It allows contracting officers to set aside or sole-source contracts to eligible woman-owned small businesses in NAICS codes the SBA has designated as underrepresented or substantially underrepresented by women-owned firms.
There are two tiers:
- WOSB — any eligible woman-owned small business in a designated NAICS code
- EDWOSB (Economically Disadvantaged WOSB) — same requirements plus additional personal financial limits; qualifies for set-asides in both underrepresented and substantially underrepresented NAICS codes
WOSB Eligibility Requirements
To qualify as a WOSB, your business must meet all of the following:
1. Ownership
- At least 51% unconditionally and directly owned by one or more women who are U.S. citizens
- Ownership cannot be subject to conditions that would transfer it away from the women owners
2. Control
- One or more women must hold the highest officer position (CEO, President, Managing Member, or equivalent)
- That woman must control day-to-day operations and long-term decision-making
- She must work full-time in the business during normal business hours
3. Small Business Size
- The business must qualify as a small business under SBA size standards for its primary NAICS code
- Size standards vary by industry — most are measured by average annual receipts or number of employees
- Check the current standard for your NAICS code at sba.gov/size-standards
EDWOSB Additional Requirements
EDWOSB status requires meeting the WOSB criteria above plus demonstrating economic disadvantage. As of 2026, the SBA applies these thresholds (sourced from SBA EDWOSB program page):
| Threshold | Limit |
|---|---|
| Personal net worth | Under $850,000 (excluding equity in primary residence and business) |
| Adjusted gross income (3-year average) | Under $400,000 |
| Total personal assets | Under $6.5 million |
Each woman claiming economic disadvantage must submit a personal financial statement (SBA Form 413) as part of the application.
Document Checklist
Gather these before starting your application. Missing documents are the most common reason for delays.
For all WOSB applicants:
- [ ] Articles of incorporation or organization (filed with your state)
- [ ] Operating agreement or bylaws, including all amendments
- [ ] Stock certificates or membership certificates showing ownership percentages
- [ ] Signed joint venture agreement (if applicable)
- [ ] Licenses, permits, or franchise agreements (if applicable)
- [ ] Three most recent federal tax returns for the business
- [ ] Proof of U.S. citizenship for each woman owner (passport, birth certificate, or naturalization certificate)
- [ ] Signed and dated WOSB program certify.sba.gov application
For EDWOSB applicants, add:
- [ ] SBA Form 413 (Personal Financial Statement) for each woman claiming disadvantage
- [ ] Three most recent personal federal tax returns (IRS Form 1040) for each woman claiming disadvantage
- [ ] Most recent personal bank and investment account statements
- [ ] Documentation of any significant assets (real estate, vehicles, retirement accounts)
The 3 Ways to Certify
Option 1: SBA Directly (Free)
Apply through certify.sba.gov. The SBA reviews your application at no cost. This is the most common path.
Processing time: approximately 30 to 60 days after a complete application is submitted. The SBA may request additional documents, which restarts the review clock.
Option 2: SBA-Approved Third-Party Certifiers (Fee Applies)
Four organizations are currently approved by the SBA to certify WOSBs and EDWOSBs:
| Certifier | Notes |
|---|---|
| WBENC (Women's Business Enterprise National Council) | Largest third-party certifier; WBENC WBE cert also accepted by hundreds of corporations |
| NWBOC (National Women Business Owners Corporation) | Focuses exclusively on federal certification |
| USKBC (U.S. Women's Chamber of Commerce) | Offers both WOSB and EDWOSB review |
| El Paso Hispanic Chamber of Commerce | Regional option; recognized nationally for federal purposes |
Third-party certifications are accepted in certify.sba.gov. You upload the certification document and the SBA recognizes it. Fees vary by certifier and business revenue — contact each organization directly for current pricing.
Which Path Should You Choose?
If cost is the primary consideration, go direct through the SBA. If you also sell to corporations and want a cert that opens both federal and corporate doors, WBENC certification covers both — you pay the fee once and upload the certificate to certify.sba.gov for federal use.
NAICS Codes Eligible for WOSB Set-Asides
The SBA designates specific NAICS codes as industries where women-owned small businesses are underrepresented or substantially underrepresented in federal contracting. The current list includes dozens of industries across construction, professional services, manufacturing, and healthcare.
Current SBA-designated examples:
- NAICS 236 — Construction of buildings
- NAICS 541 — Professional, scientific, and technical services (many sub-codes)
- NAICS 611 — Educational services
- NAICS 621 — Ambulatory health care services
The full designated NAICS list is published at the SBA WOSB program page. Check it before assuming your NAICS code qualifies — not every industry is included.
How to Find WOSB Set-Aside Opportunities
Once certified, search for contracts on SAM.gov (System for Award Management), the official federal contracting opportunity database.
Step-by-step:
- Go to sam.gov/content/opportunities
- Click Advanced Search
- Under Set-Aside Type, select Women-Owned Small Business (WOSB) and/or Economically Disadvantaged Women-Owned Small Business (EDWOSB)
- Add your NAICS code to filter to your industry
- Set a Response Date range to see active opportunities
- Save your search to receive email alerts for new postings
Contracting officers can also make sole-source awards to WOSBs under specific dollar thresholds, so not every opportunity will appear as a public competitive solicitation. Building relationships with agency small business offices increases your access to these awards.
Maintaining Your Certification
WOSB certification through the SBA does not automatically expire, but you must:
- Recertify annually through certify.sba.gov by confirming your eligibility
- Update your profile within 30 days of any change that could affect eligibility (ownership changes, officer changes, size)
- Notify the SBA if you exceed the size standard for your primary NAICS code
Failure to update can result in decertification and potential penalties on federal contracts.
Frequently Asked Questions
Can an LLC qualify for WOSB certification? Yes. LLCs, corporations, partnerships, and sole proprietorships are all eligible. What matters is that women unconditionally own at least 51% of the business and control it. For LLCs, membership interest and operating agreement control provisions both matter.
Does my business need to be incorporated in a specific state? No. The program is federal. Your business must be legally organized in the United States, but there is no state restriction.
Can I hold both WOSB and 8(a) certifications? Yes. Many businesses hold multiple SBA certifications simultaneously. The programs have separate eligibility criteria and separate application processes. Being in 8(a) does not disqualify you from WOSB, and vice versa.
How long does third-party certification take compared to SBA direct? It varies by certifier. WBENC, for example, typically processes applications in 60 to 90 days. SBA direct is often faster — 30 to 60 days for a complete application — but WBENC's process also results in a corporate-recognized certification with broader use beyond federal contracting.

What changed and why:
One edit: "Key examples from the current SBA-designated list:" became "Current SBA-designated examples:" — the original phrasing was a mild meta-announcement of the list rather than just labeling it.
Everything else was already clean. No buzzwords, no em-dash parallelism, no connectors, no hedges, no AI-vivid prose, no "in today's" opener. Front matter has all nine required fields (title, seo_title, slug, article_type, meta_description, excerpt, reading_time_minutes, author_name, tags).
