What WOSB certification is
The Women-Owned Small Business (WOSB) Federal Contracting Program is a set-aside program administered by the Small Business Administration. It reserves certain federal contract competitions exclusively for women-owned firms, similar to how 8(a) reservations work for socially and economically disadvantaged businesses.
Congress created the program to address a documented gap: women-owned firms are underrepresented as federal prime contractors relative to their share of the overall business population. The SBA identified 83 NAICS industry codes where that underrepresentation is statistically significant. Contracts in those industries can be set aside for WOSB or EDWOSB (Economically Disadvantaged WOSB) competition alone.
This is not a voluntary diversity program. It is a statutory federal procurement mechanism. Contracting officers at federal agencies are required to consider WOSB set-asides when they have adequate competition among certified firms.
Eligibility requirements
To qualify as a WOSB, your business must meet all of the following:
Ownership. At least 51% owned and controlled by one or more women who are U.S. citizens. Ownership through a holding company or trust does not qualify unless the women directly own the operating entity.
Size. You must qualify as a small business under the SBA size standard for your primary NAICS code. For most manufacturing industries, the cap is 500 employees. For most service industries, it is based on average annual receipts. In most WOSB-eligible industries, the receipts cap runs between $8 million and $30 million, though it varies by NAICS. Check the SBA's size standards table at sba.gov for your specific code.
Control. Women must hold the highest officer position (CEO or President) and control day-to-day management. If a man holds operating authority while a woman holds the title on paper, you will not survive a certification review or a protest.
For EDWOSB. If you want access to contracts reserved for economically disadvantaged women-owned businesses, each woman owner must also show personal net worth below $850,000 (excluding primary residence and business equity), adjusted gross income averaged over three years below $400,000, and total assets below $6.5 million.
How to apply
There are two paths: SBA self-certification and third-party certification.
SBA self-certification. You create an account at certify.sba.gov, complete the online application, upload documentation, and self-certify. Required documents include articles of incorporation or organization, operating agreements or bylaws showing ownership percentages, a copy of your business license, proof of U.S. citizenship for each woman owner, and a signed certification narrative explaining who controls the business. Self-certification went through major changes in 2023. Since the National Defense Authorization Act of 2020 took full effect, self-certification requires SBA review and approval rather than a simple attestation. Budget two to four weeks for SBA to process a complete application.
Third-party certification. The SBA recognizes four third-party certifiers:
- WBENC (Women's Business Enterprise National Council)
- NWBOC (National Women Business Owners Corporation)
- El Paso Hispanic Chamber of Commerce
- U.S. Women's Chamber of Commerce
Third-party certification from any of these is accepted in lieu of the SBA self-certification process. WBENC certification is the most widely recognized because it satisfies both federal procurement and corporate supplier diversity programs simultaneously. For an Arizona business, WBENC certification routes through the Western Regional Certification Program. Expect a 60 to 90 day process and a fee that scales with revenue, generally $350 to $1,250 annually.
If you plan to pursue both federal contracts and Fortune 500 supplier diversity programs, WBENC is the more valuable credential because it serves both audiences.
What contracts it unlocks
A contracting officer can set aside a contract for WOSB or EDWOSB competition when the contract is in one of the 83 designated NAICS codes and the officer has a reasonable expectation of receiving offers from at least two certified WOSB firms at a fair market price. The set-aside threshold is $250,000 to $4 million for most industries, up to $6.5 million for manufacturing.
Beyond set-asides, WOSB certification makes you visible in SAM.gov's supplier search. Federal buyers use SAM.gov to identify small businesses for market research before solicitations go live. An active, accurate SAM.gov registration with your WOSB certification codes is how contracting officers find you before a solicitation is published.
Arizona context: federal buyers and installations
Arizona has significant federal procurement activity, which creates real opportunity for certified WOSB firms.
The Department of Defense has a large footprint in the state. Luke Air Force Base (Glendale) and Davis-Monthan Air Force Base (Tucson) are active buyers of maintenance, logistics, IT, facilities, and professional services contracts. Marine Corps Air Station Yuma handles substantial support contract activity. The Army Corps of Engineers, Los Angeles District, manages construction and engineering projects across Arizona.
The Department of Veterans Affairs operates the Phoenix VA Health Care System and the Southern Arizona VA Health Care System in Tucson. VA medical centers consistently rank among the most active small business contract issuers. Healthcare services, IT, facilities management, and supply contracts are common vehicle types.
The General Services Administration manages federal real estate and vehicle fleet contracts across the region. The Department of Homeland Security (including CBP and Border Patrol) has active procurement for border infrastructure, IT, and logistics along Arizona's southern border.
Get free help: Arizona APEX Accelerator at Arizona State University
The Arizona APEX Accelerator, housed at Arizona State University, provides free one-on-one counseling to help small businesses get certified, register in SAM.gov, find relevant opportunities, and prepare bids. APEX Accelerators (formerly PTACs) are federally funded specifically to help small businesses compete for government contracts.
If you are starting from scratch or working through the certify.sba.gov application for the first time, an APEX counselor can walk you through the documentation requirements and review your application before submission. This is free. There is no reason to pay a consultant for the basic certification process when this service exists.

Arizona state-level certifications that complement WOSB
WOSB is a federal designation and carries no weight with the State of Arizona's procurement system directly. For state and local contracts, you want separate certification.
Arizona does not have a standalone state-level WBE certification administered by the state government. However, the Arizona Department of Transportation administers the DBE (Disadvantaged Business Enterprise) program, which certifies women-owned and minority-owned businesses for ADOT and federally-funded transportation projects in Arizona. DBE certification is worth pursuing if transportation, construction, or engineering contracts at the state and local level are part of your target market.
For corporate procurement programs and some local government programs, WBENC certification serves as the de facto WBE credential. Many Arizona municipalities and major corporations with Arizona operations accept WBENC certification in their supplier diversity programs.
NMSDC's Arizona affiliate, the Arizona Minority Business Enterprise Center, issues MBE certification for minority-owned businesses. If the firm is both women-owned and minority-owned, stacking WOSB, WBENC, and MBE certification maximizes the number of procurement programs you can access.
Estimated timeline
Completing the process from start to finish typically takes six to twelve weeks depending on your path and document readiness.
Getting SAM.gov active takes five to fifteen business days if your information is clean and there are no issues with your UEI (Unique Entity Identifier). Do this first. Nothing else works without an active SAM.gov registration.
SBA self-certification at certify.sba.gov, once you have your documents assembled, takes two to four weeks for SBA review of a complete application.
WBENC third-party certification takes sixty to ninety days from application submission to certificate, including the review and possible site visit.
The practical sequencing: activate SAM.gov, then start the SBA or WBENC application while SAM processes. Do not wait until SAM is active to start gathering your documents.
