# Import contacts via CSV file

Only Owners and Admins can add contacts to Inbox via a CSV file.

&#x20;

### Prepare your file

When preparing your file for upload, please be aware of the following:

* You can import a maximum of 100,000 contacts
* The file must be a .CSV file with commas as separators
* Headers must be named: phone, email, firstName, lastName, displayName. You can include custom attributes that you want to include in the contact. To do this, create a header with the name of the attribute you’d like to add. Eg: custom:account\_id.

If you are unsure how to format your file, we have an example file available for download at the bottom of the [**Import Contacts**](https://inbox.messagebird.com/contacts/import) pop-up, which you can also access on this page.

&#x20;

### Upload your contacts

1. Log in to [Inbox](http://inbox.messagebird.com/).
2. Click the [**Contacts**](https://inbox.messagebird.com/contacts) icon on the sidebar.
3. Click [**Import Contacts**](https://inbox.messagebird.com/contacts/import). A pop-up window will appear. <br>
