Restoring transparency and reliability to the field of Sifrei Torah, Tefillin and Mezuzos
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.
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 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.
Create a worldwide STa”M market that is 100% transparent and regulated.
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.

Artificial Intelligence
Every problem detected by the program is flagged and presented to the computer checker (a STAMP-certified magiah), allowing him to either validate or reject the issue. With the ability to not only receive feedback but also to give it, the program detects the differences between issues that were validated and issues that were rejected, thereby improving the accuracy of its detection moving forward.
Ability to detect additional halachic issues
In addition to detecting spelling errors with pinpoint accuracy, STAMP’s computer checking system is built to identify a slew of other halachic issues: misshaped letters (tzuras ha’osios), detection of mixed writing styles, spacing issues (including shiur parsha), disconnected crowns (tagin), and more..
Feedback for Magihim
When a magiah concludes his manual check, he scans the item and the results of his work are then entered into the STAMP computer checking database. Rabbonim and supervisors are then able to use that information to offer helpful feedback to improve his checking skills.
The life of each article
Each article is paired with a unique QR code which provides the buyer with the article’s full history and biography: Who wrote it, when it was written, which materials were used, who checked it, when it needs to be checked again, etc.
Ability to ID the Sofer’s writing
In an effort to ensure that a sofer is only submitting articles that he wrote, STAMP’s computer checking system is able to match the ksav (“handwriting”) of each item with the sofer who wrote it.
Ability to ID each individual article
As it is impossible for any two STa”M items to be identical, every item can be scanned in order to discern whether or not an article was originally STAMP-certified even years after it was purchased.
