Transferring WIC from Oklahoma to Illinois
The move does not cost you WIC. Your Oklahoma clinic issues a Verification of Certification on request, and that document enrolls you with Illinois Department of Human Services in Illinois for the rest of your certification period. Without it you can still apply fresh, but the VOC skips the income re-check.

Your step-by-step checklist
Before you move
- 1
Ask your current WIC clinic for a VOC card
Before you leave Oklahoma, ask your local WIC clinic for a Verification of Certification (VOC) card — Oklahoma publishes a dedicated VOC request line at (405) 426-8504. Federal rules (7 CFR 246.7) require your new state to accept the VOC, so your certification moves with you for the rest of its period. General OK WIC line: (405) 426-8500 / toll-free (888) 655-2942.

Carry the VOC with your moving documents
Your current state's WIC food benefits stop working after you leave its issuing system, but the VOC keeps your certification alive.
After you arrive

Contact Illinois Department of Human Services and book a transfer appointment
Bring the VOC and proof of your new address. With a valid VOC you are enrolled without a new income screening until your current certification period ends. Stated timing: up to 20 days.

What exactly is the VOC card?
The Verification of Certification is a document your current WIC clinic issues that proves you are certified. Federal rules (7 CFR 246.7) require every state agency to accept it, so Illinois enrolls you without a new income screening until your certification period ends.
What if I forgot to get a VOC before leaving Oklahoma?
Call your old Oklahoma clinic — many can send the VOC or verify your certification for Illinois Department of Human Services directly. If that fails, you can apply fresh in Illinois; WIC's income limit is the same 185% of the federal poverty level in every state.
Will my Oklahoma WIC benefits card work in Illinois?
No — WIC benefits are issued on each state's own system, so the Oklahoma card stops working. Your certification transfers via the VOC; Illinois Department of Human Services reissues the food benefits on Illinois's system.
Where do I actually apply in Illinois?
Through Illinois Department of Human Services (online application linked above). Official WIC pages for both states are cited at the bottom of this page.
