| **`name`** *         | To be used as the property name when stored and retrieved from the database.  |
| **`label`**          | Used as a field label in the Admin panel and to name the generated GraphQL type. |
| **`min`**            | Minimum value accepted. Used in the default `validation` function. |
| **`max`**            | Maximum value accepted. Used in the default `validation` function. |

| **`index`**          | Build a [MongoDB index](https://docs.mongodb.com/manual/indexes/) for this field to produce faster queries. Set this field to `true` if your users will perform queries on this field's data often. |

| **`defaultValue`**   | Provide data to be used for this field's default value. |
| **`localized`**      | Enable localization for this field. Requires [localization to be enabled](/docs/configuration/localization) in the Base config. |

### Admin config

In addition to the default [field admin config](/docs/fields/overview#admin-config), this field type allows for the following `admin` properties:

**`step`**

Set a value for the number field to increment / decrement using browser controls.

**`placeholder`**

Set this property to define a placeholder string for the field.

**`autoComplete`**

Set this property to a string that will be used for browser autocomplete.

### Example

`collections/ExampleCollection.js`
```js
{
  slug: 'example-collection',
  fields: [
    {
      name: 'age', // required
      type: 'number', // required
      required: true,
      admin: {
        step: 1,
      }
    }
  ]
}

```
