Pinning a WhatsApp conversation results in pinning to one of the top three positions in the general list. No more than three dialogs can receive the “pinned” status at the same time.

In addition to the location, the icon with the image of a “pushpin” helps to distinguish a pinned entry from others.

Each subsequent pinned element is automatically placed one line higher than the previous one. You won’t be able to manually prioritize by dragging a conversation to the desired position. A user who needs to rank priority items must apply the pinning option in a specific order.

The messenger settings allow you to set your own alert tone for each pinned conversation.
