Good things, by the plate.

A little courtesy,
by the plate.

Message any car by its plate: a quick heads-up, a thoughtful thank-you. Claim your own plate if you have one, so people can reach you too.

Made for iPhone, with a web companion.
You don’t need a car to send a message.

worth saying.

Simple, from the start.

Small notes.
Good intentions.

A little help can start with a plate. Here’s how.

  1. 01

    Start with the plate.

    Enter the region and the plate number, by camera or keyboard, and check every character before you go on. You don’t need a car or a plate of your own.

  2. 02

    Send one message.

    A heads-up, a thank-you, a thoughtful note. First contact is a single message request that the owner can accept or decline before the conversation continues. An unclaimed plate can’t receive messages yet.

  3. 03

    Claim yours, if you have one.

    Claiming a plate is optional. Add one to be reachable through it, and claim only a vehicle you drive and have permission to use. Replies stay with the people in the conversation.

One message, then their call.

A first hello,
kept simple.

Your first contact with a plate is one message request. The owner can accept it and reply, or decline it. Nothing continues until they choose, and accepting a conversation never makes you friends.

Please don’t handle your phone while driving. Send and read messages when you’re safely parked.

How message requests work
Example message request

Hi! Your trunk is open.

One message to start.
The owner chooses what happens next.

Illustrative example

Private is the starting point.

Your plate
can be enough.

You decide what more someone gets to know.

Privacy, in plain language

A plate-first profile.

One personal profile covers your account. Each vehicle has its own details and privacy choices. Everything stays hidden until you turn it on; there’s no person-to-plate directory.

Friendship goes both ways.

Friend requests are separate from conversations, and accepting a conversation never makes you friends. You can remove a friend, stop contact, or report a message.

The owner decides.

A first message is only a request. The owner can accept or decline it before anything continues, and you can stop contact at any time.

The Platd beta doesn’t use your location. Read the details.

Room for a longer conversation.

Your desktop companion.
Your Android option.

Use the responsive web app to message plates, manage your own, and catch up on conversations, with the same privacy controls. Camera support depends on your browser and device.

Open web app

Good to know.

A few questions,
before hello.

Do I need a car to use Platd?

No. You can message any plate and receive replies without a car or a plate of your own. Claiming a plate is optional; it lets people message you through it.

What happens after I send the first message?

The owner sees one message request and can accept or decline it. The conversation continues only if they accept. Accepting never makes you friends.

About message requests
Do I have to be named on the title?

No. Claim the vehicle you drive and have permission to use. Loans, leases, company cars, and family cars all fit the honor-based claiming model.

What if someone has already claimed my plate?

Request a review and attach a registration photo. Your evidence stays private. An authorized person reviews the claim and records a decision; the public app does not automatically give the plate to either person.

About claim reviews
Can a plate be real but absent from Platd?

Yes. “Not claimed in Platd” means no driver has claimed it here, so it can’t receive messages yet. It is not a government registration check. Plate designs are chosen by the driver; the look is not proof of registration or ownership.

Can I use Platd while driving?

Please don’t handle or look at your phone while driving. Send and read messages when you’re safely parked.

Can I install it now?

The access page lists the current iPhone and web options. If an installation option is not available yet, it is clearly marked there.
