The serial number of your SteriPEN will be located in one of two locations depending on which model of SteriPEN you have.
- For SteriPENS that have replaceable batteries: The serial number will be located on a sticker inside the battery compartment.
- For SteriPENS that are USB rechargeable: The serial number will be etched onto the plastics of the SteriPEN.
Your SteriPEN’s serial number will consist of both letters and numbers. The number will start and end with two letters and the middle of the serial number will consist of numbers. You will need the entire string of letters and numbers to register your SteriPEN.
You might find a number like 3058969 on your SteriPEN. This isn’t the serial number. The serial number will contain both letters and numbers.
