## Installing

```shell
npm install vbb-translate-ids
```


## Usage

```js
const {to12Digit, to9Digit} = require('vbb-translate-ids')

assert.strictEqual(to12Digit('900003201'), '900000003201')
assert.strictEqual(to9Digit('900000003201'), '900003201')
```

If `to12Digit`/`to9Digit` don't know how to translate the ID, they will just return it.
