# Do not create new Contacts

## What it is[​](#what-it-is "Direct link to What it is")

Stops auto‑creating CRM contacts when messages arrive from unknown numbers. No new contact records are created automatically via this integration.

## Where to find it[​](#where-to-find-it "Direct link to Where to find it")

<Steps>
  <Step>
    Go to Locations → WhatsApp Numbers
  </Step>

  <Step>
    Open an instance (e.g., WhatsApp #1)
  </Step>

  <Step>
    In the right panel, enable “Do not create new Contacts”
  </Step>
</Steps>

Instance‑level only. Each WhatsApp number can have its own setting.

## How it works[​](#how-it-works "Direct link to How it works")

* Disabled (default): inbound messages from unknown numbers create a new contact
* Enabled: inbound messages from unknown numbers do not create a new contact

No impact on existing contacts or manual contact creation.

## When to use[​](#when-to-use "Direct link to When to use")

* You want to keep the CRM clean during trials/POCs
* Lead capture happens elsewhere (forms, checkout, internal tools)

## Notes & limitations[​](#notes--limitations "Direct link to Notes & limitations")

* Does not retroactively delete existing contacts
* Applies only to the selected instance; other instances are unaffected
