Change your prefix contact's phone number

Features & Capabilities

Contacts Prefix Fixer is a Chrome extension designed to help you edit and standardize the prefix of phone numbers saved in your contacts. Whether you want to add international prefixes like +84 to local numbers or fix inconsistencies caused by merged contact sources, this tool simplifies the process.

Many mobile plans, such as AT&T Prepaid, require dialing strict 10-digit numbers. Prefix prefixes or local 7-digit numbers can interfere with plan renewals or cause unnecessary charges. This extension automates prefix correction and removes duplicate numbers within the same contact to prevent such issues.

As an upgraded version of the previous "Change Prefix phone number" app, Contacts Prefix Fixer supports more CPU types and provides a robust, user-friendly solution for managing your phonebook efficiently.
