How can I verify that 16603-28020 is a genuine Toyota part?

We can supply the commercial invoice, packing list and, on request, a Certificate of Origin for any shipment.

As a Toyota Genuine Parts number, 16603-28020 is the same across markets; where another catalog lists a different number for the same function, that number is the superseded one – confirm with our sales team before dispatch.
