Fix Telegram Error 420 FLOOD_WAIT Temporary Ban (2025)

Updated: 11/29/2025

You are chatting or testing a bot on Telegram, sending messages quickly, and suddenly a request fails with Error 420 FLOOD_WAIT or a warning about being temporarily banned. After that, certain actions stop working for minutes or even hours, even though other apps on your phone are fine. This code means Telegram’s anti spam system has flagged your activity as too fast or too automated, and you need to slow down and adjust your usage so it does not happen again.

Method 1: Understand The FLOOD_WAIT Timer And Stop Spamming

Do not forward the same message to dozens of chats, add hundreds of users to groups at once, or repeatedly join and leave large groups. These behaviors look like spam to Telegram and are much more likely to cause FLOOD_WAIT bans even for legitimate accounts.

Method 2: Implement Rate Limiting And Queues For Bots And Scripts

For bots that must send many notifications, route outgoing messages through a queue system that drips them out gradually rather than all at once. A simple scheduler that spaces requests evenly can eliminate most FLOOD_WAIT errors without impacting users too much.

Warning: Trying to bypass Telegram limits by rotating through multiple accounts or phone numbers violates their terms and can lead to permanent bans, so design within the official constraints instead.

Method 3: Use Alternative Communication Patterns During Cooldown

If you run a public bot, update its help or about message to explain that rapid commands or floods of interactions can trigger temporary slowdowns. Setting user expectations reduces spammy behavior that would otherwise keep hitting FLOOD_WAIT limits repeatedly.
