- Back or side of the indoor air handler (for ductless wall units or mini splits)
The label contains the brand (Bosch), model number, and a long alphanumeric serial number.
Sample Bosch Serial Number Formats
Bosch has used different serial number formats over the years. For American heat pumps, the following formats are most common:
| Serial Format Example | Year Code Location | Month Code Location |
|---|---|---|
| 8733953160123456789 | First few digits (after the model code) | Next two digits (often after year code) |
| 82191210322333 | 1st and 2nd digit | 3rd and 4th digit |
| HD91234567 | 3rd and 4th digit | 5th and 6th digit |
Most modern Bosch heat pump serial numbers include the year and month of manufacture within the first 6-8 digits.
Decoding Current Bosch Serial Numbers
Take for example the following serial number format:
Serial Number: 873395316021900899
- Digit 11-12: “19” = Year of manufacture (2019)
- Digit 13-14: “00” = Month of manufacture (January, or “00” may mean batch)
To confirm, cross check with Bosch’s official documentation or contact their customer support with your serial number for specific details.
Older Bosch Serial Number Decoding
For models manufactured before 2010, the serial may use a different layout. Examples:
- 1st or 2nd digit: Year (9 = 2009)
- Following 1-2 digits: Month (01 = January, 12 = December)
If uncertain, reference the product manual or the Bosch HVAC distributor for your region.
Step-By-Step Example: Decoding Your Bosch Heat Pump’s Age
Let’s decode a typical American Bosch heat pump serial number:
- Locate the data plate label and write down the serial number.
- Identify the key year and month digits per the above guidance.
- Match the number to the corresponding production year and month.
- Contact Bosch HVAC support if unsure, giving them your full serial number and model.
Example: Serial – 873395316021902458. The 11th and 12th digits “19” mean it was made in 2019.
Why Bosch Serial Number Decoding Guides Vary
Bosch periodically revises its coding structure across product lines. Ductless heat pumps and water-source units may follow a slightly different format than inverter split systems. Overseas Bosch heat pumps may also use a European date code standard.
Always refer to model-specific documentation for the most accurate details or consult Bosch Thermotechnology’s American support for clarity.
