# `BROKER_NAME_ALREADY_USED`

## Description

Authentication cannot use the ZITADEL organization with the requested Broker
name. The organization is the Quarzo Organization, belongs to another Broker, or
lacks matching `brokerId` metadata. Broker onboarding returns the same error
from Authentication. The rejected request creates no project grant, Exchange
Client, or user.

## HTTP Status

`409 Conflict`

## `doc_url` Format

`<docs-base-url>/errors/broker_name_already_used`

## How To Fix

Use an available Broker name. If this request resumes interrupted provisioning,
ask Quarzo operations to verify the organization ownership and metadata.
