WIC is not an entitlement program. Congress does not set aside funds to allow every eligible individual to participate in the program. Instead, WIC is a federal grant program for which Congress authorizes a specific amount of funding each year for program operations. The Food and Nutrition Service, which administers the program at the federal level, provides these funds to WIC state agencies (state health departments or comparable agencies) to pay for WIC foods, nutrition education, breastfeeding promotion and support, and administrative costs.
The WIC program is available in all 50 States, 34 Indian Tribal Organizations, American Samoa, District of Columbia, Guam, Commonwealth Islands of the Northern Marianas, Puerto Rico, and the Virgin Islands. These 90 WIC State agencies administer the program through approximately 2,200 local agencies and 9,000 clinic sites.
