How can I verify that 28100-31131 is a genuine Toyota part?
A genuine Starter Motor shows the Toyota number 28100-31131 on the box label with the country-of-origin marking. On the part itself, the OE supplier’s mark is moulded or etched on the component next to the Toyota number (DENSO on coils and sensors); and the connector has the factory-keyed pin count and latch geometry that only one position on the harness accepts. Documentation is available on request – commercial invoice, packing list and Certificate of Origin.

You get one piece per position – check the quantity required for your application.
Is the genuine part worth it compared with an aftermarket equivalent?
The genuine part differs in ways that show up in service: the unit is calibrated to the factory signal range, so the ECU reads it without fault codes, and the factory-keyed connector plugs straight into your harness with no adapters or rewiring. These are the aftermarket equivalents you may also see quoted.
What documentation comes with an order?
Commercial invoice and packing list accompany every shipment, and a Certificate of Origin can be issued on request; the part number is laser-etched on the housing, so you can match it against the invoice.
