# ZIP

To connect to a proxy using a ZIP code, add and specify the `zip` parameter with a five-digit ZIP code in the username, combined with the `cr` country code parameter.

Here are a few examples of valid combinations of country and zip parameters:

`cr.us;zip.85032`

`cr.fr;zip.75001`

**Code example**

In this example, a query to gw\.dataimpulse.com is performed from an IP address from New York, USA:

```
curl -x "http://login__cr.us;zip.10001:password@gw.dataimpulse.com:823" https://api.ipify.org/
```

{% hint style="info" %}
It's important to note that selecting a country is mandatory to specify city, state, ZIP code, and ASN targeting.
{% endhint %}

***

You can now exclude specific ZIP codes using the `nozip` parameter.

**Example:** To target Germany but exclude ZIP code 10115, use:

`cr.de;nozip.10115`

{% hint style="info" %}
Traffic routed through the `nozip` parameter, as well as `zip` parameter is billed at double the standard rate.
{% endhint %}
