OU Product Not Found on Website

Why are some products that bear the OU symbol not listed on http://www.oukosher.org?

The OU website provides a search field for OU certified products. Kosher consumers are sometimes surprised when they do not find OU products on the website. In truth, not all OU certified products are recorded online, as some companies have asked that their certified products not be posted for a variety of reasons. If you are uncertain if an OU symbol is authorized, please contact the OU office.
