Identification guide
Bosch date code
In Bosch date code, Bosch appliance FD numbers and codes on electronic components use different systems from this Professional-tool format.
Product number versus serial prefix
On the documented nine-digit Professional-tool serial format, the leading three digits encode a year digit and two-digit month. A prefix such as 709 denotes September in a year ending in 7; the product’s production period identifies the decade.
Three-digit prefix example
| Part | Reading |
|---|---|
| 7 | Year ending in 7; decade from model period |
| 09 | September |
| Remaining serial digits | Unit information |
What to check next
Keep the complete serial and product number together. Bosch appliance FD numbers and codes on electronic components use different systems from this Professional-tool format. Do not apply an appliance decoder to a drill label.
