What the plate is
Every listing is issued a short code in the shape ML-XXX-XXX when it is created. It appears on the listing as a plate badge, and it is unique across the whole of MotorLoop, so no two cars anywhere share one.
The plate is also the address. Typing motorloop.com.au followed by the plate opens that car directly, which makes it something you can read out over the phone without spelling a single slash.
It travels with the photos
The plate badge is stamped into the photos the listing serves publicly. When a picture is saved, forwarded or reposted, the plate goes with it, and anyone who ends up looking at the photo has a way back to the car and the seller.
It is the same badge on the social share card, so a link shared to a group chat arrives showing the plate rather than a bare address.
Why it is useful in the real world
A card under the wiper with a plate on it works at the shops, at a meet, or at the front of the driveway. Somebody photographs it, types eleven characters, and is looking at the full listing with every photo and the whole specification — instead of squinting at a phone number and hoping the ad still exists.
It is also the thing to quote on the phone. "It is M L, four E F, E Z R" survives a bad line in a way a long web address does not, and it gets the caller to the same page you are looking at.
One plate, one car, for as long as the listing exists
The plate is issued by the site rather than chosen, and it is checked for uniqueness across every marketplace running on MotorLoop — not just the one the car is listed on. That is what makes it safe to print: a code that could belong to two cars would send half the people who typed it to the wrong one.
It stays with the listing for its whole life, so a card printed the week the car went up still works the week it sells. When the car does sell, the plate keeps resolving to the listing rather than breaking, which matters when the picture with the plate on it is still circulating.
