Why has WhatsApp blocked me?: Being suddenly banned from WhatsApp can be frustrating, especially if you use the platform for business or marketing communications. A block can manifest itself with messages saying "this number is not authorized to use WhatsApp" or simply temporary limitations on features. Let's explore the most common reasons and how to prevent future blocks based on best practices and tips. WhatsApp Business Official API.
Main causes of blockage
- Mass sending without "human" behavior
WhatsApp identifies excessively fast or regular sending patterns as suspicious activity. If you send hundreds of messages in sequence without random pauses, the system may intervene with a suspension. - Lack of consent (opt-in)
Emails to users who haven't expressly consented to them are flagged for spam, increasing the risk of being banned. - Using unofficial tools
Software that relies on scraping or unauthorized interfaces is constantly detected and automatically blocked. - Unapproved templates
Transactional messages (e.g. appointment confirmations) sent outside of Meta-validated templates are rejected or flagged as potential abuse. - Sensitive content or inappropriate language
Political promotions, offensive invitations, or content prohibited by WhatsApp policies may result in immediate reporting.
How to check the reason for the block
