How to Apply to Become a WIC Vendor

Becoming a WIC Vendor is a multi-step process. Most stores complete all steps within 2-3 months, depending on how quickly documents are submitted, training is completed, and the Point-of-Sale (POS) system is certified. You cannot be authorized until every step has been completed.

Step 1: Review Requirements

Before you start, make sure your store meets the basic WIC vendor requirements:

You must stock all items on the WIC Minimum Stock List.
You must buy all infant formula from an Illinois WIC Authorized Formula Supplier.
You must have a certified Point-of-Sale (POS) system ready to process WIC transactions.
Your prices must be competitive with other stores in your area.

Step 2: Gather Your Documents

Have these documents ready to upload with your application:

Proof of ownership or business registration
- Example: Articles of Incorporation, Business License, or Bill of Sale showing current ownership.
Proof of compliance with local business or health regulations
- Example: Most recent health inspection report (showing you are approved to sell perishable foods) OR a current business license issued by your city/county.
Federal Employer Identification Number (FEIN) or Social Security Number (SSN)
- Example: IRS letter showing FEIN, or Social Security card if the business uses an SSN.
Proof of identity for all owners, partners, and officers of the company
- Example: State-issued photo ID (driver's license or state ID card) for each listed individual.
Proof of SNAP status (if applicable)
- Example: USDA SNAP Authorization letter showing store name, location, FNS Number, and current authorization status.

Step 3: Complete the Online Application

The application must be signed by the owner or someone legally authorized to sign for the company.
Submit all documents with the application. If something is missing, DHS will email you. You must respond within 10 days.
Review the Application Form Guidance if you are unsure of how to respond to any of the questions.
There are two types of applications. Be sure to choose the right one:

New Store Application

Use this if your business has never been authorized as a WIC Vendor or you wish to re-apply.

Add a Store (Same Ownership)

Use this if your business is already authorized and you want to add another store under the same ownership of an already authorized WIC Vendor.

Step 4: Shelf-Price Survey

DHS will send you a shelf-price survey through DocuSign.

You must complete it within 30 days.

This ensures your store meets competitive pricing rules.

Step 5: Initial Training

If your application passes the first review, DHS will send you a link to the online training modules.
At least one store representative must watch all videos and complete the certificate of completion.

Step 6: Site Visit & Interactive Training

After training is complete, DHS will schedule a virtual site visit and interactive training (WebEx).
A store representative must walk through the store with a smartphone or tablet (video and audio enabled).
Your store must show that it meets the Minimum Stocking Requirements.
If you do not pass, you may request a re-check within 30 days. Two failed visits will result in denial.

Step 7: Probationary Authorization & Contract

If the site visit is passed, DHS will send a probationary authorization and vendor contract via DocuSign within 7 days.

The contract includes your WIC Vendor ID (X9 number). This number must be shared with your POS provider.

Step 8: POS Certification

Contact your POS provider immediately.
Share the X9 number and certification instructions.
Work with your provider to:
- Meet all EBT Operating Rules.
- Print correct receipts.
- Ensure the Authorized Product List (APL) is downloaded daily.
Map all fresh produce correctly.
Staff must be trained on how to process WIC transactions.

Step 9: Live Validation

Within 60 days of probationary approval, you must complete a test Balance Inquiry with the WIC test card.
DHS will then schedule an in-store live validation.
If your POS system passes, you will receive full authorization within 7 business days.

Important Reminders

Once probationary authorization is issued, your store is required to follow all contract requirements, WIC rules, and regulations.
- If your store is found to be in violation of WIC Program rules during the probationary authorization period, your application will be denied.
If your application is denied, you cannot reapply for at least 180 days (per state vendor rules).
Deadlines matter: missing the 14-day, 30-day, or 60-day deadlines in the application process may result in denial.
