Edit Prefix is a free utility application designed for Android users who need to efficiently modify the prefixes of their contact telephone numbers. The app simplifies the process by allowing users to search for a specific prefix they wish to change, generating a list of relevant contacts. Once the desired prefix is identified, users can easily update it to a new number with just a click, ensuring a smooth transition for their contact list.

In addition to its core functionality, Edit Prefix offers extra features for user convenience. Users have the option to exclude specific numbers from the update process before finalizing changes, providing greater control over their contact management. The app breaks down updates into manageable batches of 100 or 300 to enhance reliability and prevent system failures. It is essential, however, for users to back up their contacts independently, as the app does not assume responsibility for any data loss.
