# City

Add a `city` parameter to narrow down to city-level targeting. For example, `country-CA-state-bc-city-castlegar` means that a proxy from Castlegar, Canada, will handle the query.

{% hint style="info" %}
We support every city worldwide, but because our Residential Proxies come from a peer-to-peer network, the availability of IPs can change at any moment. Since peers can go offline at any time, we cannot guarantee that a specific city will always have active IPs available.
{% endhint %}

Here are a few examples of valid combinations of `country, state` and `city` parameters:

`username-country-EG-state-ast-city-asyut`<br>

`username-country-DE-state-ni-city-badessen`

`username-country-GT-state-09-city-quetzaltenango`

`username-country-ZA-state-gp-city-alexandra`
