Current Twitter Limits

What are the limits?

We don’t limit the number of followers you can have. However, we do monitor how aggressively users follow other users. We try to make sure that none of our limits restrain reasonable usage, and will not affect most Twitter users.
We monitor all accounts for aggressive following and follow churn (repeatedly following and un-following large numbers of other users). You can read more about these below, but if you don’t follow or un-follow hundreds of users in a single day, and you aren’t using automated methods of following users, you should be fine. Please note that the only automated following behavior that Twitter allows is auto-follow-back (following a user after they have followed you). Automated un-following is also not permitted. Please review our Automation Rules and Best Practices for more information on automating your account.

The current technical limits for accounts are:

• Direct Messages: 250 per day.
• Updates: 1,000 per day. The daily update limit is further broken down into smaller limits for semi-hourly intervals. Retweets are counted as updates.
• Changes to Account Email: 4 per hour.
• Following (daily): Please note that this is a technical account limit only, and there are additional rules prohibiting aggressive following behavior. You can find detailed page describing following limits and prohibited behavior on the Follow Limits and Best Practices Page. The technical follow limit is 1,000 per day.
• Following (account-based): Once an account is following 2,000 other users, additional follow attempts are limited by account-specific ratios. The Follow Limits and Best Practices Page has more information.

These limits include actions from all devices including web, mobile, phone, API, etc. API requests from all third-party applications are tracked against the hourly API limit. People who use multiple third-party applications with their account will therefore reach the API limit more quickly. For more information on this topic, please see our API Rate Limiting Page.
These limits may be temporarily reduced during periods of heavy site usage. In such cases, we will post an update at the Twitter Status blog.
