# Introduction

We allow member to register his cars - e.g. for some benefits related to parking.

The number of cars member may register is limited - see: [configuration](api-3510806). 

Car is identified by its registration number. We require the number to be valid according to format specific in a country it is registered in.

The car is treated as valid/active for specific number (see: [configuration](api-3510806)) of days after the registration. It may be automatically deleted after this time.
The member may renew the car using [this](api-3510841) API method.

## Member Car Model

<DataSchema id="560742" />

### Example

```json

  "id": 5813951,
  "country": "NO",
  "registration_number": "AB12345",
  "color": "white",
  "make": "Toyota Corolla",
  "expires_at": "2024-11-02T15:12:59.189512Z",
  "created_at": "2023-11-03T15:12:59.190629Z",
  "updated_at": "2023-11-03T15:12:59.190629Z"
}
```

## Registration Number (LPN) normalization
  
Across system, LPN is always normalized to a standardized form:

* whitespace is removed
* a-z characters are converted to upper case

Examples:

| Original | Normalized  |
| --- | --- |
| `ka123` | `KA123`  |
| `fr 333 456` | `FR333456` |
| `wf joker` | `WFJOKER` |
