What you need to know
- Entries with 10 or 11 digits receive prefix 55. All instances refers to the account, not all platform clients.
- This is not a native WhatsApp block and does not prevent group messages involving that person, manual sends or other automations.
- LID identification in replies may limit phone matching; do not treat the list as an absolute block across every identification form.
