Why does WhatsApp work if the number is blocked - briefly?

WhatsApp can still function even if a number is blocked due to its unique messaging protocol that operates independently of traditional SMS and call systems. This allows messages to be delivered through an internet connection rather than relying on cellular networks.

Why does WhatsApp work if the number is blocked - in detail?

WhatsApp, one of the most popular messaging platforms globally, offers users a high degree of privacy and control over their communications. One common question that arises in this context is why WhatsApp messages can still be received even if the sender's number has been blocked by the recipient. This phenomenon can be attributed to several factors that underpin the architecture and functionality of the platform.

Firstly, it is essential to understand that blocking a contact on WhatsApp does not necessarily prevent them from sending messages. When a user blocks another user, the primary effect is on the visibility and notification aspects of the communication. Specifically, blocked users cannot see the recipient's last seen status or online presence, and their messages do not trigger notifications for the recipient. However, the messages themselves can still be delivered to the recipient's device, albeit in a manner that does not alert them immediately.

This discrepancy arises because WhatsApp operates on an end-to-end encrypted model, ensuring that messages are securely transmitted between users without interception by third parties. The blocking feature is more about user experience and control over interactions rather than preventing message delivery altogether. When a blocked user sends a message, it is still routed through WhatsApp's servers to the recipient's device but is handled differently due to the block status.

Moreover, WhatsApp employs a sophisticated system of message queues and delivery protocols. Messages from blocked users are placed in a queue and can be delivered when the recipient becomes active on the platform. This means that even if the recipient has not actively opened WhatsApp or checked their messages, they may still receive the communication at some point. The exact timing and method of delivery can vary depending on various factors, including network conditions and device settings.

In summary, while blocking a number on WhatsApp limits the interaction's visibility and immediate impact, it does not entirely prevent message delivery. This design choice ensures that users have control over their communication experience without completely severing potential lines of contact, providing a balance between privacy and connectivity.
