Applying H4 based H1B premium process

Hello! Yesterday (04/30), we received the receipt number for the H-1B application (premium processing), and we are now applying for H-4 status for myself (spouse) and our child. My question is: what is the correct physical mailing address to send our H-4 application to?
According to the USCIS instructions, receipt numbers that begin with "IOE" should be sent to Phoenix, AZ lockbox. However, my husband’s H-1B case (filed online) is being processed at the California Service Center. Where should we send our application in this case?
Also, should we write the H-1B receipt number on the outside of the envelope? I’m concerned that the H-1B might be approved before our H-4 is processed, which could leave us out of status. Thank you for your help!
