Between the Lock and IS on/off switch. It should also be on the box and the warranty card.

It's just a good check to make sure someone didn't swap box/lens. That's why I like the reg card, it's exactly as it appears on the lens <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span></P><P>I've had this lens for a while now and really love it. I also had the EF version for my DSLR's. Just amazing lenses.</P><P>Newton&nbsp;</P> Thu, 07 Mar 2024 20:58:21 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/Where-is-the-serial-number-my-new-100mm-2-8-macro-lens/m-p/466245#M30111 FloridaDrafter 2024-03-07T20:58:21Z https://community.usa.canon.com/t5/EF-RF-Lenses/Where-is-the-serial-number-my-new-100mm-2-8-macro-lens/m-p/466257#M30112 <P>I had the old EF 100mm - great lens but no IS ...
