# How to Request KYB Verification

Know Your Business (KYB) verification reviews your business and proxy use case.

KYB may grant access to financial websites and services, HR platforms, and feedback websites.\
KYB also provides a higher account-wide thread limit.

KYB does not enable additional proxy ports.

### When to request KYB

Request KYB when your business needs access to:

* financial websites or services
* HR platforms
* feedback websites, such as Trustpilot and G2, etc.

KYC remains required for every customer. KYB is an additional review for eligible business use cases.

### Before you request KYB

Prepare:

* your exact proxy use case
* supporting business documents

We may request a short interview. This helps us understand your use case.

### Request KYB verification

Contact Proxidize Support through either channel:

* email <support@proxidize.com>
* use live chat

Include your proxy use case and supporting business documents. The team reviews each request internally and contacts you after the review.

{% hint style="info" %}
KYB approval applies only to approved website categories and use cases.
{% endhint %}

### What KYB does not change

These restrictions apply to both KYC and KYB customers:

* Ports other than `80` and `443` remain blocked.
* Government websites with `.gov` domains remain blocked.
* Military websites with `.mil` domains remain blocked.
* Survey-for-money websites remain blocked.
* Adult-content websites remain blocked.

Use of Proxidize proxies must remain within the approved use case.

### Thread limits

KYC customers have a limited number of concurrent threads across their accounts.

KYB customers receive a higher account-wide thread limit after approval.

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.proxidize.com/getting-started/kyc-verification-for-proxidize-proxy-users/how-to-request-kyb-verification.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
