Company Setup Toolkit allows you to import postcode data from a file in bulk instead of inserting new record manually by hand.
It will not overwrite existing postcode if one already exists in your database.
- Open the Postcodes page.
- Select Import Postcodes on the Action bar.
- Select the file for import.
- Wait for the import to complete.
File Format for Postcode Import
The file format is text, tab-separated values. Do not include a header row.
