Vendor Application Process

Any store owner may apply for WIC authorization. There is no charge for application or re-authorization. WIC-authorized stores must meet certain requirements for stocking products that can be bought with WIC benefits, and must also charge competitive prices and have a good business reputation. Stores must apply for re-authorization every three years.

The Maine CDC will accept requests for WIC vendor applications on an ongoing basis.

The stores are limited by geographic area and participant density in that area. If a new store is interested in WIC authorization, then the Maine CDC will only send a WIC application to that store if there is an opening in that new store's geographic area.

Minimum Qualification and Requirement

  • A vendor applicant shall be an established business, open to the public for at least one year in the current location.
  • Must have a fixed location that includes refrigeration and freezer equipment in the retail area.
  • Must carry foods intended for home preparation and consumption in addition to the WIC required minimum stock items
  • At least 1000 square feet of space devoted to the sale of grocery items unless denial for this reason would result in inadequate participant access.

Minimum Inventory Requirements Checklist

Vendor Price Survey

Please provide us with your store highest pricing for WIC-approved products in each category of food using the price survey (PDF). Price Surveys are used to determine the Maximum Allowable Reimbursements, to aid us in deciding a fair reimbursement for rejected drafts, and to determine if a store meets WIC’s pricing parameters. It is important that you complete the survey accurately, carefully and thoroughly. List only the highest available priced WIC-approved item. Refer to your Booklet for Vendors for WIC approved foods. Do not list foods or package sizes that are not WIC approved.


Infant Formula From Authorized Supplier
