A letter of certification is the document your customers use to confirm your products are kosher — and knowing how to read it helps you use it as a sales tool.
What’s on it — The certifying agency and symbol, the exact products covered, the designation (pareve, dairy), any special standards, and the expiration date.
How buyers verify — Reputable agencies let customers confirm a certificate is current and covers the specific product.
