When using this method, if you don’t add an account, the new contact is private.
To create a contact that’s automatically associated with an account, create the contact in the account’s detail page.
If your Salesforce org uses record types, you’re sometimes prompted to choose a Record Type when creating a contact. Different record types can have different fields and picklist values.
If your Salesforce org uses divisions, the division of a new contact is automatically set to the division of the related account.
Always associate a contact with an account, unless you have a specific reason not to. Contacts without accounts are hidden from all users except their owner and system administrators, which makes them hard to find and easy to forget.
