Viber is one of the world’s most popular messaging apps with over 1 billion registered users, especially dominant in Eastern Europe, the Middle East, and Southeast Asia. But every time you need to message someone on Viber — a delivery driver, a landlord, a seller on a marketplace — the default process is the same: save their number, open Viber, find the contact, then start chatting. It works, but it clutters your contacts list with people you may never talk to again.
There is a better way. Viber supports a deep link protocol that lets you open a conversation with any number without saving it first. OPN Chat makes this feature accessible through a simple, free web interface.
Why Would You Want to Viber Without Saving a Number?
Consider these everyday situations where saving a contact is unnecessary:
- Marketplace transactions — You found a seller on OLX, Jumia, or Lazada and need to ask about an item. One message, done.
- Delivery drivers — A courier is bringing your package and shares their number for coordination. You need to chat once, not forever.
- Business inquiries — Reaching out to a hotel, restaurant, or service provider for a quick question.
- Travel — Communicating with taxi drivers, tour guides, or Airbnb hosts while abroad, especially in countries where Viber is the primary messenger.
- Networking — You met someone at an event and want to follow up without adding them to your permanent contacts.
In all these cases, the person does not belong in your phone book. You just need a fast, one-time conversation on Viber.
How Does It Work?
Viber uses a deep link format: viber://chat?number=%2B{phone_number}. When you open this link, it launches a Viber conversation with that number — no contact saving required. The %2B is the URL-encoded + sign, which Viber requires before the country code.
OPN Chat simplifies this process. Instead of manually constructing deep links, you:
- Enter the phone number with the country code (for example, 380 for Ukraine, 966 for Saudi Arabia, 66 for Thailand).
- Optionally write a message that will be pre-filled in the chat.
- Click “Open Chat in Viber” — and you are taken directly to the conversation.
That is it. No sign-up, no data stored on any server. Everything runs inside your browser.
Important: Unlike WhatsApp, Viber does not have a web fallback. Viber must be installed on your device for the deep link to work — on mobile, you need the Viber app; on desktop, you need Viber Desktop installed and running.
Step-by-Step Guide
- Go to opnchat.net/viber — the Viber without saving number tool page.
- In the phone number field, enter the full number without the + sign. For example, for a Ukrainian number +380 50 123 4567, type
380501234567. - If you want to start with a pre-written message, click “Add a message” and type it in.
- Press the purple “Open Chat in Viber” button.
- Viber opens (the app on your phone or Viber Desktop on your computer) with a new conversation ready to go.
Note: If Viber does not open, make sure the Viber app is installed on your mobile device or Viber Desktop is installed and running on your computer. The deep link requires a Viber client to handle it.
Is It Safe and Private?
Yes. OPN Chat does not store, log, or track any phone numbers or messages you enter. The tool simply generates a Viber deep link and opens it in your browser. All communication happens through Viber’s own end-to-end encrypted infrastructure. OPN Chat never intercepts or reads your messages.
Your recently used numbers are saved locally in your browser’s localStorage for convenience only — you can clear them at any time by clearing your browser data. Nothing is ever sent to our servers.
Common Questions
