OPN Chat now supports Viber — the popular messaging app with over 1 billion users worldwide. Our Viber Direct Chat tool lets you open a Viber conversation with any phone number instantly, without saving the contact first. Simply enter the number with the country code, and you'll be taken straight to the chat in Viber.
Reaching out to someone on Viber usually means saving their number to your contacts first. With OPN Chat, you can skip that step entirely.

OPN Chat uses Viber's official deep link protocol (viber://chat) to open a chat directly. Enter the phone number with the country code — no spaces, no dashes. Optionally, add a pre-filled message. Click "Open Chat in Viber" and the Viber app opens on that conversation. No sign-up, no data stored on servers — everything runs in your browser.

OPN Chat uses the viber://chat deep link protocol, which is Viber's official way to open a chat directly. The format is viber://chat?number=%2B{country_code}{phone_number} where %2B is the URL-encoded + sign. This deep link is recognized by the Viber app on both iOS and Android. Important: Viber must be installed on your device for this to work. On desktop, Viber desktop app must be running.
