You can import your contacts or address book from GrandCentral, Outlook, Hotmail, Yahoo!, and other services, into Google Voice. To get started, you need to export your contacts into a CSV file. Contacts exported from other mail providers are sometimes already formatted as CSV files, or you can create your own CSV file.
Once you have a CSV file with all your contacts' information, follow these steps:
- Sign in to Google Voice.
- Click Contacts on any Google Voice page.
- Click Import in the top right portion of the Contacts section.
- Click the Browse... button and find the CSV file you'd like to upload.
- Select the file and click the Import button and your contacts should be transferred to Google Voice.
