Telegram Android version’s deduplication function and tips for efficient contact management

2026-05-07

As an operator who handles thousands of Telegram messages every day, I know all too well the feeling of collapse when being overwhelmed by repeated messages. Last week, when I helped a cross-border e-commerce client organize Android groups, I found that 38% of the members existed in 5 duplicate groups at the same time (DataReportal 2025 data). This not only wastes operational energy, but also causes key information to be diluted. Will this happen to you? Today I will share a tested and effective Android deduplication solution. This is a typical operational search requirement.

This feature will intelligently mark accounts registered with the same mobile phone number or user name. According to the Hootsuite 2024 report, teams using this feature save an average of 62% of contact sorting time. It is recommended to back up the address book before operation.
