# `payer_personal_iban_already_registered`

`payer_personal_iban_already_registered`

## Description

The IBAN provided is already registered for this payer during payer creation.

## HTTP Status

`409 Conflict`

## `doc_url` Format

The `doc_url` value is an absolute URL and changes by environment:

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

## Typical Causes

* The same IBAN was supplied again when creating a new payer for the same subscriber.

## How To Fix

1. Use a different, unregistered IBAN.
2. If the IBAN should be reused, use the existing payer or register it via the personal IBAN endpoint.
