COR is a trusted kosher certification agency — relied on by 1,200+ facilities, from first-time startups to global brands. Big enough for global brands. Small enough to still answer the phone.
We've streamlined the process so you can focus on growing your business. Our staff walks you through every stage of establishing a kosher program that's right for your company.
A senior Rabbinic Coordinator reviews your application and arranges an initial inspection visit.
Your coordinator visits your facility to evaluate what's needed to set up your kosher program.
We draft an agreement outlining the terms, requirements, and obligations of certification.
You're approved to carry the COR seal — trusted by consumers around the world.
Obtaining kosher certification helps you market to additional demographics and clearly differentiate your products — and kosher appeals well beyond the Jewish community, including halal-adjacent, allergy-conscious, and vegan and vegetarian consumers. Every applicant is assigned a dedicated Rabbinic Coordinator who provides clear, step-by-step guidance from your very first call.
