RF600mm cannot find serial number

I just bought a RF600mm f4.0 from B&H. I try to register my lens, but cannot find serial number. Can anyone help me to find it? Thanks

Greetings,

😊

Its on the lenses box

Its on your B&H receipt

Its on rhe USA Warranty Card

Its also on the lens.

Either on this black ring or the lens barrel itself

Here's a link to your other post:

Also verify that the serial on the lens is the same as the other sources.

Yes, thanks! The tag is reflecting. It is hard to see without proper light
