Department M, along with the Stasi OTS (Operativ-Technische Sektor), developed and implemented numerous technical tools, intelligence checks, and operational activities to speed their postal surveillance in the GDR. By the 1970’s, the department was already using various modified household appliances or industrial devices to assist in steaming open and closing letters. One example is this […]
In the beginning of the 1970s most of the work of Department M was performed by hand. This labor included sorting and selecting suspicious mail, manually steaming it open, examining the contents, transcribing, copying or photographing the interior or exterior of the letter, in some cases, examining the letter for conspiratorial or stealth writing, resealing […]
Today I made this diagram to describe the manual labor and flow of mail from the Deutsche Post stream through the Stasi’s Department M surveillance operations. It’s a fairly boring flow chart but gets at the heart of the organizational processes and divisions of labor they developed to speed their work. […]
Similar to how Facebook uses a user’s connections to determine information about them, the Stasi considered all information they could gather about a person in their intelligence campaigns. They incorporated not only the contents of a target’s mail, but information about professional and personal relationships, love affairs, and organizations to which they belonged. (Reinicke, 106) […]

During the seven years Gerd Reinicke worked for Department M the scope of surveillance grew steadily. This is particularly evident in the 1980s, when as the government became more and more concerned of the “class struggle,” they dramatically increased the number of operators in Department M, more than doubling the size from 1980 to 1989. […]
In the essay, “Eavesdropping for the class struggle: Postal control of the Stasi,” from the book, “Secret readers in the GDR: Control and distribution of illicit literature” (ed. Siegfried Lokatis), Gerd Reinicke describes his work in the “evaluation and information” section of the Stasi’s Department M. He explains his job was to assess and classify […]
Thanks to the implementation of index cards across the MfS, Department M had access to sender and receiver addresses, contacts, relatives, etc. to inform their surveillance work. By 1970, the department had instituted the following operational steps for examining mail. Numbers 3–6 were considered highly secretive and operations were performed under the codename “Eagle Flight”. […]

The number of cards in the Stasi indexes grew to an incredible 39,000,000 by 1989. In order to provide constant access to this massive material data system they created various special storage units and containers as it expanded. The current mechanical powered card indexes in place at the BTsU were found after the end of […]

The VSH index card system was yet another data storage method developed by the Stasi for monitoring and controlling the population. Introduced in 1974, the system used a red F401 card for all “secretly policed” persons, and a corresponding white F402 information card once that person was captured and began informing for the MfS. The […]

A Stasi Kerbloch card The Stasi used several other card systems to assist their postal surveillance. The Kerblochkarten (English: Kerbloch cards) system allowed storage of data encoded as a series of hand-made notches. Like other punch card systems, groups of cards could then be automatically processed by a machine based on the presence of notches […]
