HOW ICQ2 WORKS
A tiny program with one big job.
Bring people together. Then stay out of their way.
Claim your legacy UIN
Enter your old number. If it is supported and still free on ICQ2, it can be yours again.
Bring your people
When a friend comes online, the room lights up. Double-click and say hi.
LEGACY
REMEMBER YOUR OLD UIN?
It may be waiting for you.
Type your old ICQ number when you create an ICQ2 account. If it is within the supported range and nobody has claimed it on the new network, you can make it yours again.
Legacy UINs are first come, first served. Claim yours before somebody else does.ICQ2 is a new independent network. Old accounts, passwords, and contact lists do not transfer automatically.YOUR LEGACY UIN12345678AVAILABLE?Check it during registration
THE GOOD PART OF THE OLD INTERNET
Find an old friend.
Make a new one.
The early ICQ idea was wonderfully direct: tell you who is online and make it easy to contact them. ICQ2 starts there again.
The contact list is the home screen.
Open ICQ2 and see friends, not content selected to keep you scrolling.
Online is an invitation, not an obligation.
A green light says “I’m around.” Away says “maybe later.” That is enough.
A messenger can just be a messenger.
No channels, stories, mini-apps, ads, or engagement tricks. We have other apps for those.
Inspired by the friendly, people-first spirit of the Mirabilis-era ICQ website from 1997 ↗. This is a new independent project, not a restoration of that service.
A DIFFERENT REASON TO OPEN A MESSENGER
Less catching up. More dropping in.
Telegram is excellent at organizing everything that arrived. ICQ2 begins one step earlier: with the people who are here.
THE USEFUL INBOXWhat happened?
Great when you need an archive, a channel, a bot, or the latest update.
THE FRIENDLY ROOMWho is here?
Great when you miss somebody and would like to know if now is a good time.
Different jobs. Different rooms. You are allowed to have both.
The old ICQ service stopped.The little green light is still a lovely idea.
