# Address Mode

> Generate envelope addresses with stricter constraints.

Set `generation_type: "address"` when generating envelope addresses.

## Constraints

* Max **5 lines** (split by `\\n`)
* Max **250 characters**
* `font_size: "auto"` is **not supported** — you must set a numeric font size (12–400)

## Example

```json theme={null}
{
  "generation_type": "address",
  "page_size": "envelope_10",
  "font_id": 1,
  "font_size": 44,
  "text": "Jane Doe\\n123 Main St\\nSpringfield, IL 62704"
}
```
