Z- Nr Bosch, Siemens decode

What is Z NR?

This is the serial number of the washing machine assembled on the assembly line.

Z- Nr. – 200430

  • 2 – assembly line number
  • 00430 – washing machine number, decoded as follows, in July 2009, this washing machine 430 came off the second assembly line. The five-digit designation allows you to assign the washing machines the number 99999, which is 3225 washing machines per day, 134 per hour, 2 per minute. Obviously, it is impossible to produce that many on a single conveyor, and 5 digits is enough to create an identification number.

Decoding the serial number of Bosch, Siemens washing machines explained

The washing machine is also assigned a serial number which contains additional information. The serial number is an additional protection entered by the washing machine manufacturer. The serial number controls the correctness of the washing machine information, in turn the serial number consists of 18 digits 489070250386004303 and can be explained as follows.

It should be noted that washing machines produced before 2000 did not have a serial number. The manufacturer only provided information about the model number, year of manufacture, and washing machine number.

How do I know what country my Bosch/Siemens/Gaggenau washing machine is made in?

Now let’s see how to understand the entire serial number from Bosch.

  • 48 – is the code of the factory where the washing machine was assembled. The factory where the washing machine is assembled is assigned an individual code. You can tell from this code in which country the washing machine was assembled. Although nowadays, of course, there is no difference where the washing machine was made. At Bosch plants operates a unified quality system, which ensures the high quality of manufactured products.
    • 40 – Germany
    • 41 – Poland
    • 42 – Germany
    • 43 – Turkey
    • 45 – Germany
    • 48 – Germany
    • 84 – Thailand
    • 85 – USA
    • 87 – China
    • 88 – Russia
    • 99 – Germany
  • 9 is the year of manufacture, the last year of the decade. The date of manufacture may be detailed in the FD number.
  • 07 – month of manufacture.
  • 0250386 – internal manufacturer code, which contains service information such as component suppliers.
  • 00430 – washing machine number
  • 3 – Serial Number Control Code, used to verify that the serial number is correct.

Fake serial number, Bosch washing machine

Sometimes there are discrepancies between the serial number, FD codes and the washer serial number. As an example in the photo above. According to the FD and Z-Nr information, the washer was produced in 2001 in May and came off the assembly line under the number 3545. According to the serial number, the washer was produced in 2001 in December and came off the assembly line under the number 90733.

It’s a fake sticker, the following says it:

  • The Z-Nr. number must consist of six digits.
  • The production date in FD and the serial number are different.
  • The number of washing machines produced by Z-Nr. is very large 3543, the production of this washing machine on the assembly line was 3543, this is produced per month. If you divide by the number of days in a month, that’s 120 a day, which is a lot, although on the big lines at the end of the month it is possible. But by serial number, that’s 90,733 washing machines. It is simply not possible to produce 90,000 washing machines a month on a single line.
  • The Z-Nr code and the ZNR code in the serial number do not match.

Those who printed the sticker did not know that the serial number must contain FD and Z-Nr information. Because the washing machine is not made by Bosch, or it is another model of an earlier model on which a fresh sticker has been affixed. Or, alternatively, the washing machine is assembled from several washing machines, then the sticker is imprinted much later.
