ANTiDOMOFONViP is an online service focused on information and tools related to apartment-building intercom systems in Russia and nearby countries. Its main offering is a searchable directory of intercom entry codes, which users can look up by address or nearby coordinates. The site says its database covers cities across Russia and the CIS, is free to access, and receives daily updates from the service and its users. Moderators also review the listings and remove codes reported as no longer working.

The service provides access through several messaging-platform bots, including Telegram, VK, Tox, Jabber, and Matrix, and offers a video guide explaining how to search for codes. Its website also features articles and reference materials about intercom codes, keys, instructions, and related topics, along with a section for complaints. ANTiDOMOFONViP reports a large user community and code collection, and states that technical support is available around the clock. It also lists other free projects and a bot-based opportunity for users to earn passively.
