WhatsApp has become an essential part of our daily communication, but many times we need to quickly message someone whose number we don't want to save—such as a delivery agent, technician, or someone we need to contact only once. Saving every temporary number can be inconvenient, but there's a simple WhatsApp trick that lets you send messages without adding the number to your contacts.

To use this feature, you must first ensure the number is active on WhatsApp. Once confirmed, simply copy or note down the number. Open WhatsApp and start a chat with yourself by searching for your own number or typing “You” in the search bar. Paste the number into the chat window and send it. As soon as the number appears as a clickable hyperlink, tap on it and WhatsApp will instantly open the chat window for that contact. From there, you can send your message directly without adding the number to your contact list.

This quick trick is especially helpful for people who frequently deal with unknown numbers, such as courier agents, delivery personnel, or customer service providers. It saves time and keeps your contact list uncluttered. You can easily use this method to share your location, send documents, or have short conversations without permanently storing the number. It’s also simple enough to teach your parents or relatives who might struggle with saving and deleting contacts repeatedly.

Alternatively, WhatsApp also allows users to open a chat through a direct link. Though slightly more technical, this option can start a conversation instantly from any browser on your phone or laptop. Once the link is clicked, WhatsApp will open a chat window with that number automatically.
