# Blacklist numbers

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

Blocks inbound WhatsApp messages from specific phone numbers on a WhatsApp number. Any message from a blacklisted number is silently dropped before it reaches your CRM, so it never appears in your conversations. Every other number keeps coming through as normal, and outbound messages you send from your CRM are never affected.

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

Instance-level only. Each WhatsApp number keeps its own blacklist.

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

* Add phone numbers to the blacklist in international (E.164) format, including the country code (e.g. +91). You can paste several at once, separated by commas or new lines.
* Inbound messages from any blacklisted number - direct or group - are dropped before they reach your CRM.
* Every other number keeps working normally, and outbound messages you send from your CRM are never affected.

Numbers are matched by their full international number, so save them with the country code. Invalid entries are rejected when you add them. You can blacklist up to 1,000 numbers per WhatsApp number.

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

* Block spam or repeat unwanted senders on a specific number
* Stop a known bad actor from cluttering your CRM inbox
* Keep a high-traffic number clean while still receiving from everyone else

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

* Applies only to the selected instance; other WhatsApp numbers keep their own separate blacklists
* Affects inbound only - it does not block or change outbound messages you send from your CRM
* Does not delete existing conversations or messages already synced
* Blacklisted senders are dropped silently - they are not notified and receive no error
* Changes take effect right away - no need to reconnect the number
