The STa”M Project

Restoring transparency and reliability to the field of Sifrei Torah, Tefillin and Mezuzos

Partner with us, as we revolutionize
the world of STa"M

STAMP is galvanizing the process of how Mezuzos, Tefillin, Sifrei Torah, Megillos and Sifrei Nevi’im are produced, ensuring that every stage is reliably executed and properly supervised. By advancing our work, you are helping ensure that Jews around the world will be able to fulfill these fundamental mitzvos properly.

The Issue

Mezuzos, Tefillin, Sifrei Torah, etc., have long been produced by individuals working independently, with no supervision. As a result, there are countless stories of STa”M articles which have been in use for years – or even decades – and subsequently discovered to be invalid. Even more alarming, countless Jews around the world are still using STa”M every day, unaware that it does even meet the most basic standards of halacha.

STAMP is now doing for the field of STa"M

Who We Are

STAMP is a nonprofit organization whose sole mission is to restore transparency and reliability to the field of STa”M (Sifrei Torah, Tefillin, Mezuzos, Megillos and Nevi’im). Our activity is under the direct supervision of five of the industry’s leading authorities: Rav Chaim Sperling, Rav Moshe Uri Bloi, Rav Don Bricker, Rav Yaakov Zions and Rav Reuvain Mendlowitz shlit”a.

STAMP was founded in 2019 by its director, Rabbi Avraham Yechezkel Lessin.

We accomplish our mission in 3 ways:


Create a worldwide STa”M market that is 100% transparent and regulated.


Educate the public about STa”M and its halachic complexities, thereby empowering the consumer to make informed purchases.


Provide guidance to the public for all STa”M-related needs.
Our comprehensive
certification process

STAMP ensures that the materials used were reliably manufactured, the Sofer and Magiah are both properly certified and that the item has passed through a multi-stage checking process. With this, buyers can purchase their STa”M with complete assurance that the item is kosher.
