The Checking

The Checking

Until Now, There Was No Process to Trust.

In today’s mezuzah market, demand is higher than supply, supply chains are non-transparent, and there’s no regulatory or quality assurance process.

This means a constant flood of mezuzahs that have not been written or checked K’Halacha are entering the market.

Hashem's protection for our homes

The mezuzah is more than the symbol of a faithful Jewish home. One of G-d’s names, ש-ד-י, is prominently inscribed upon the back of the scroll. This is an acronym for שומר דלתות ישראל, [Hashem is] the Guardian of the Doors of Israel.
Unlike human kings hidden away and guarded by servants, G-d Himself protects every Jewish home.

Frequently Asked Questions

What is the full pikuach (oversight) process?
The OU and its partners will only accept the products of reliable sofrim who maintain regular certification.  The unique handwriting of participating sofrim will be documented and referenced by cutting-edge technology to ensure that all mezuzos that are presented are indeed the work of those sofrim. Each mezuzah is checked by magihim (trained inspectors for STa”M and experts in the laws of Sta”M). Each mezuzah is also checked by sophisticated software. The software is programmed to check the mezuzos for accuracy. After the process is complete and the mezuzah is deemed to be kosher lechatchila (kosher according to generally accepted halachic standards), it is wrapped in tear-proof plastic. Each mezuzah will be accompanied by an informational card bearing the ‘OU STA"M’ logo, the logo of the OU partnering organization, and the individual mezuzah’s information.
What is the difference between ‘pikuach’ for mezuzos and kosher certification for food?
There are certain things, such as the intent of the Sofer while he writes, that are simply impossible to see. Pikuach represents the oversight of the parts of the process that can be verified.
Does the OU’s involvement make mezuzos more expensive?
No. The OU is providing this oversight as a service to the community. There is no OU organizational fee layered into the final price of the mezuzah.
