Serial numbers for professional equipment made after 1999 will have either 9 or 11 digits.

For example:

• 054200362

• 05-4200362

• 2005-4200362

Here's how to read them:

• The first two digits represent the year (e.g., 05 = 2005).

• The next two digits indicate the week of the year (e.g., 42 = calendar week 42).

• The last five digits show the sequential production number (e.g., 00362 indicates the unit was number 362 in production order that week).

This format will help you identify the manufacturing details of your equipment.
