# Código postal

El tráfico enrutado a través de este parámetro se factura al doble de la tarifa estándar

Para conectarse a un proxy usando un código ZIP, agregue y especifique el `zip` parámetro con un código ZIP de cinco dígitos en el nombre de usuario, combinado con el `cr` parámetro de código de país.

Aquí hay algunos ejemplos de combinaciones válidas de parámetros country y zip:

`cr.us;zip.85032`

`cr.fr;zip.75001`

**Ejemplo de código**

En este ejemplo, se realiza una consulta a gw\.dataimpulse.com desde una dirección IP de Nueva York, EE. UU.:

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

{% hint style="info" %}
Es importante señalar que seleccionar un país es obligatorio para especificar la ciudad, el estado, el código ZIP y la orientación por ASN.
{% endhint %}

***

Ahora puede excluir códigos ZIP específicos usando el `nozip` parámetro.

**Ejemplo:** Para orientar a Alemania pero excluir el código ZIP 10115, use:

`cr.de;nozip.10115`

{% hint style="info" %}
El tráfico enrutado a través del `nozip` parameter, as well as `zip` parameter is billed at double the standard rate.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.dataimpulse.com/dataimpulse-documentation-es/proxies/parametros/codigo-postal.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
