What WOSB certification is
The Women-Owned Small Business (WOSB) Federal Contracting Program is a federal set-aside program run by the Small Business Administration. It allows federal contracting officers to restrict competition on certain contracts to WOSB-certified firms. The goal is to increase the share of federal contract dollars going to women-owned businesses, which have historically received a smaller share than their numbers warrant.
There is also an Economically Disadvantaged Women-Owned Small Business (EDWOSB) designation for owners who meet additional income and asset thresholds. EDWOSB firms qualify for a narrower but more exclusive pool of set-asides.
Eligibility requirements
You must meet all of the following to qualify as a WOSB:
Ownership. Women must own at least 51% of the business. For corporations, women must own at least 51% of each class of voting stock and 51% of the aggregate of all stock outstanding.
Control. One or more women must control the management and daily operations of the business. The highest officer position must be held by a woman.
Size. The business must qualify as a small business under SBA size standards for the NAICS code the contract is assigned to. For most industries, the revenue cap is $30 million in average annual receipts over three years. Manufacturing industries use employee count instead. Check the SBA's size standards tool at sba.gov to confirm your specific NAICS threshold.
Citizenship. Each woman claiming ownership must be a U.S. citizen.
For EDWOSB status, the owner must also demonstrate economic disadvantage: personal net worth below $850,000 (excluding equity in the business and primary residence), adjusted gross income averaged over three years at or below $400,000, and total assets not exceeding $6.5 million.
The 83 NAICS industries where WOSB set-asides apply
WOSB set-asides are not available on every federal contract. The SBA has designated 83 NAICS industry codes where women-owned firms are underrepresented in federal contracting. These span sectors including architectural and engineering services, educational support services, janitorial services, certain construction trades, computer systems design, marketing research, and several manufacturing categories.
EDWOSB set-asides apply to a subset of those same 83 codes where women-owned firms are substantially underrepresented.
Before you apply, confirm that your primary NAICS code is on the designated list. The current list is published at sba.gov/document/support-wosb-program-eligible-naics-codes.
How to apply
You have two routes.
Route 1: SBA self-certification. Go to certify.sba.gov and create an account. You upload documentation directly, SBA reviews and approves, and your certification lives in their system where contracting officers can verify it. SBA self-certification is free. The documentation required includes proof of ownership (operating agreement, articles of incorporation, or stock certificates), a copy of your business license, and personal financial documents if you are applying for EDWOSB status. Processing time varies but typically runs four to eight weeks.
Route 2: Third-party certification. SBA recognizes four third-party certifiers: the Women's Business Enterprise National Council (WBENC), the National Women Business Owners Corporation (NWBOC), the El Paso Hispanic Chamber of Commerce, and the U.S. Women's Chamber of Commerce. If you already hold certification from one of these organizations, you can use it to qualify for WOSB set-asides by uploading proof to certify.sba.gov. WBENC certification is the most widely recognized and also unlocks corporate supplier diversity programs, which makes it a strong choice if you are pursuing both federal and corporate contracting.
Regardless of which route you take, your certification must be active and in the SBA system before a contracting officer can award you a WOSB set-aside contract.
California-specific context
California is one of the largest federal contracting markets in the country. The state hosts major federal buyers across defense, technology, agriculture, healthcare, and infrastructure.
Active federal buyers in California include the Department of Defense (installations include Naval Base San Diego, Camp Pendleton, Edwards Air Force Base, Travis Air Force Base, and several others), the Department of Veterans Affairs (which operates medical centers in Los Angeles, San Diego, San Francisco, and Palo Alto), the General Services Administration's Region 9 office (which covers the Pacific Rim), and the Department of Agriculture (Forest Service, Natural Resources Conservation Service). NASA's Jet Propulsion Laboratory in Pasadena and Ames Research Center in Mountain View are significant R&D buyers as well.
The NAICS codes most relevant to California's economy that appear on the WOSB designated list include computer systems design and related services (NAICS 541512), management consulting (NAICS 541611), advertising agencies (NAICS 541810), and various construction and facilities services codes.
Free help from the California APEX Accelerator
If you are not sure whether you qualify or want help with your application, contact the California APEX Accelerator. APEX Accelerators (formerly called Procurement Technical Assistance Centers, or PTACs) are federally funded and provide free one-on-one advising for businesses pursuing government contracts. They can help you confirm eligibility, identify the right NAICS codes, review your certification application before submission, and connect you with contracting opportunities at nearby federal installations.
The California APEX Accelerator has advisors across the state. You can find your nearest location through the APEX Accelerator locator at apexaccelerators.us.
State-level certifications that complement WOSB
California has its own certification programs that serve different buyers. They do not replace WOSB but stack well with it.
California Department of General Services (DGS) Small Business and DVBE. California certifies Women Business Enterprises (WBE) and Disabled Veteran Business Enterprises (DVBE) for state agency procurement. This is separate from WOSB and targets California state contracts rather than federal ones. Applications go through the DGS online portal.
Caltrans DBE Program. If you work in transportation-related services or construction, Caltrans administers the Disadvantaged Business Enterprise (DBE) program for federally funded transportation projects. DBE certification is run at the state level but required by U.S. DOT. Women who are presumed socially and economically disadvantaged can qualify. DBE certification is required on specific highway, transit, and airport projects that receive federal funds.
NMSDC MBE Certification. For women of color, National Minority Supplier Development Council certification as a Minority Business Enterprise (MBE) is issued through the Southern California Minority Supplier Development Council or the Northern California Supplier Development Council. MBE certification targets large corporate buyers rather than government agencies. It is a separate credential with a separate application process.
Holding multiple certifications is common and practical. A business with WOSB, California WBE, and WBENC certification can pursue federal set-asides, California state contracts, and Fortune 500 corporate programs without re-proving ownership and control each time.
Estimated timeline and process steps
Allow roughly six to twelve weeks from start to active certification if you are doing SBA self-certification. Here is the realistic sequence:
- Confirm your NAICS code is on the WOSB designated list.
- Pull together ownership documentation: operating agreement or articles of incorporation, stock ledger if applicable, business license, and federal tax returns for three years.
- Create an account at certify.sba.gov and complete the online application.
- Upload required documents. SBA will notify you if anything is missing.
- SBA reviews the application. Processing typically takes four to eight weeks, though it can take longer during high-volume periods.
- Once approved, your WOSB status is visible to federal contracting officers in the System for Award Management (SAM.gov). Make sure your SAM registration is active and current before your certification is approved.
If you pursue WBENC certification as a third-party route, their process involves a paper application, document review, and an in-person or virtual site visit. WBENC's timeline is typically eight to twelve weeks from submission to approval, and their annual fee structure varies by business revenue.
Recertification is required annually. Put a calendar reminder three months before your anniversary date to avoid a lapse that could disqualify you from active bids.
