The STa”M Project

Bringing transparency and reliability to the field of STa”M

The STAMP Certification

I’d like to buy a STa”M product

The need

STAMP is a nonprofit organization, operating under the direct supervision and guidance of leading rabbanim and sofrim, whose mission is to restore transparency and reliability to the world of STa”M, using a state-of-the-art, professional approach. 

What kashrus agencies did for our food, STAMP is now doing for our STa”M.  

What is STAMP?

Why Does Your STa”M Need Certification?

Nobody questions the need for kashrus supervision.  We understand the necessity of supervising a field with complex halachos where it is so easy for mistakes to occur.  

Yet the field of STa”M, which is similarly complex and prone to error, operates without any supervision whatsoever.  The vast majority of Jews are using STa”M written by sofrim whom they have never met, who work independently with no organized oversight system of accountability.  This has created a worldwide situation where STa”M products are sent to market without any reliable way of knowing whether or not they are kosher.

In response to this untenable state of affairs, a group of prominent rabbanim and sofrim came together and decided:  It’s time to change this situation.

The STAMP Revolution

Comprehensive Supervision to Ensure Your STa”M is Kosher

the Public

STAMP raises public awareness about STa”M and its halachic requirements, thus empowering the consumer to know what to look for when purchasing.

Promoting Fair
Trade Standards

STAMP seeks to correct the historic underpayment of sofrim and magihim, as well as streamline the process by which the STa”M item gets from the sofer to the customer, reducing the number of intermediaries involved.


Unique QR code tracking system STAMP has created a unique computerized system for every STa”M product under its supervision, to enable consumers to easily access the full history of the article: who wrote it, who checked it, what materials were used, what style writing was used, etc.


Responding to the current severe global shortage of magihim, STAMP runs a specialized program to train new magihim.

Comprehensive Certification

STAMP provides certification for the sofrim, the materials and the STa”M articles themselves, ensuring halachic compliance at each of the three levels of the STa”M production process. Thus, the consumer can be confident that any item with the STAMP seal is halachically reliable.

How Your Mezuzah Gets to Your Door:
The STa”M Process

The kosher klaf and ink are then purchased by a sofer, who writes the parshios (Torah passages) contained in each mezuzah, bearing in mind all the laws of writing each letter . 


The completed parshios are sent on to magihim for checking, to ensure there are no mistakes.  This checking process is a halachically-required step. In fact, halachic sources recommend two rounds of proofreading – a practice which STAMP’s magihim are careful to adhere to.


The klaf is manufactured from the hides of a kosher animal, which are processed in a halachically prescribed manner to create parchment.


The ink, which must be black, is prepared with a specific recipe of ingredients which have been in use for thousands of years.
