Figuring Out COAs

From a few reputable suppliers I've used, I've noticed this. Often they include their company name but omit the batch number. The certificates of analysis are consistently solid, and the vials tend to be slightly overfilled.
 
That's how they try to make you believe the batch they're selling is the one the CoA corresponds to.
 
If you check with Janoshik, there ought to be an image showing what color the cap is.

That's my method for confirming the vial I receive matches the one that was tested. Your results may differ.

Isn't it true that the actual manufacturers are basically never known?
