Important Kellogg’s Company and Ownership Update
The original Kellogg Company no longer operates as one combined cereal, snack, and frozen-food company. In October 2023, the business separated into WK Kellogg Co and Kellanova.
- WK Kellogg Co: Produces and markets Kellogg’s breakfast cereals in the United States, Canada, and Caribbean. Ferrero acquired WK Kellogg Co in September 2025.
- Kellanova: Retained brands in global snacking, international cereal, noodles, and North American frozen foods. Mars acquired Kellanova in December 2025.
The Kellogg’s name therefore appears on products managed by different companies. Consumers should identify the product before choosing a customer-service department.

Food-Safety, Illness, or Allergic-Reaction Concerns
Do not consume cereal or another food product that appears contaminated, spoiled, improperly sealed, or unsafe.
If someone becomes ill, is injured, or experiences a possible allergic reaction, seek appropriate medical assistance. CorporateOfficeHeadquarters.com cannot diagnose an illness or determine whether a particular product caused a medical condition.
When reporting a food-safety concern, retain the package, remaining product, receipt, photographs, UPC, printed date, and manufacturing codes. Follow the company’s instructions for safely storing or returning the product.
Kellogg’s Refund, Coupon, and Product-Availability Questions
Retailers generally control store prices, shelf tags, returns, and immediate refunds. Contact the store first when a concern involves an incorrect register price, damaged product purchased at that location, or a retailer-specific promotion.
WK Kellogg Co Consumer Affairs may assist when the concern involves:
- A company-issued coupon
- A national Kellogg’s promotion
- Product packaging or manufacturing quality
- Difficulty finding a cereal
- A discontinued or reformulated variety
- Feedback about ingredients, taste, package size, or value
Product selection can vary by retailer and region. A cereal missing from one store may still be available through another retailer.

WK Kellogg Co has positions involving cereal manufacturing, food safety, supply chain, sales, marketing, finance, information technology, engineering, corporate operations, and other business functions.
Job seekers should use the official WK Kellogg Co Careers website to search for openings and submit applications. The Consumer Affairs number is intended for product and consumer questions, not employment applications.

About Kellogg’s and WK Kellogg Co
The Kellogg cereal business traces its history to Battle Creek, Michigan, where W.K. Kellogg helped develop flaked cereal in the late nineteenth century. The Kellogg Company was established in 1906 and grew into one of the world’s best-known packaged-food companies.
In October 2023, Kellogg Company separated its North American cereal business as WK Kellogg Co. The remaining Kellogg Company changed its name to Kellanova.
WK Kellogg Co continued operating from One Kellogg Square in Battle Creek, concentrating on cereal products in the United States, Canada, and Caribbean. Ferrero completed its acquisition of WK Kellogg Co in September 2025, making the cereal company a wholly owned Ferrero business.
Kellanova retained many snack, cracker, frozen-food, and international cereal brands before becoming part of Mars in December 2025. This history explains why current Kellogg’s support depends on the product and country involved.
Kellogg’s Competitors and Related Corporate Office Pages
WK Kellogg Co competes in the breakfast cereal and packaged-food industry with companies such as General Mills, Post Consumer Brands, and private-label cereal manufacturers. Broader packaged-food and snack competitors include Kraft Heinz, Mondelez International, Frito-Lay, and PepsiCo.
Ferrero also owns Keebler. However, consumers should remember that Keebler cookies and former Keebler-branded crackers may have different support departments.
