FD Number Checker
An FD number is a production number used by Bosch, Siemens and NEFF. It is normally printed on the rating plate beside the E Nr model information. The checker uses the FD production code rather than the normal serial number for these brands.
Use Appliance Age Checker
Select the appliance brand and type. The form will tell you whether to enter an FD number or serial number.
Open the checkerWhy the brand matters
There is no single universal appliance serial format. Bosch, Siemens and NEFF use an FD production number. Samsung has published serial date codes. LG and AEG encode date information in the serial but can leave the exact decade ambiguous. Other brands use formats that can differ by product line or production period.
What if the code does not identify one year?
The checker does not ask for an approximate decade. If the information on the label is not enough to identify one reliable year, the result says that the age cannot be determined from that number for that brand.
