Step No.1: Open the new Google Contacts website in your browser and sign into your Google Account.
You need to enter your credentials and click on the Sign in button. Make sure you’ve signed in the same Gmail ID, which is attached to your contacts. Once done, you will be taken to the contact’s profile of your account.
Step No.2: Navigate to “Restore Contacts”
This option is listed in the left sidebar and will open a popup window to select a timeframe. In case this option does not appear, you can click on the More button in the left sidebar and get the required option.
Step No.3: Select a restoration period from the list
Now, you will need to choose a time period from the given options. You can also restore your contacts from a custom period if you do not want to use the default time periods.
This button is at the bottom of the restoration period window and will revert your contacts to the state they were at the selected restoration period.
Once you are done, your deleted contacts will be restored. Its worth noting that you will only be able to restore deleted Google contacts within the period of 30 days.
