# City

You can add a city header parameter together with the 2-letter **ISO 3166-1 alpha-2** country code to target a specific city. For example, using `customer-USERNAME-city-us_chicago` will request a proxy specifically from Chicago, United States.

Examples of a few cities that you can target in the `city` parameter:

| City        | City parameter        |
| ----------- | --------------------- |
| Los Angeles | `city-us_los_angeles` |
| London      | `city-gb_london`      |
| Munich      | `city-de_munich`      |

### Request example

{% tab title="cURL" %}

```bash
curl --proxytunnel --proxy "https://customer-USERNAME-city-us_chicago:PASSWORD@proxy.goproxies.com:1080" https://ip.goproxies.com
```

{% endtab %}

{% tab title="JavaScript" %}

```javascript
const axios = require('axios');
const { HttpsProxyAgent } = require('https-proxy-agent');

const username = 'customer-USERNAME-city-us_chicago'; // example
const password = 'PASSWORD';
const proxyAuth = encodeURIComponent(username) + ':' + encodeURIComponent(password);
const proxyUrl = `http://${proxyAuth}@proxy.goproxies.com:1080`;
const agent = new HttpsProxyAgent(proxyUrl);

(async () => {
  try {
    const res = await axios.get('https://ip.goproxies.com', { httpsAgent: agent, timeout: 10000 });
    console.log(res.status, res.data);
  } catch (err) {
    console.error('request error:', err.message);
  }
})();

> Note: City header will have priority against State and Country, so if used together those headers will be ignored.
