How do I add additional phone number to my account 

[VanKalkerFarms · Accepted solution]

you don't add phone numbers to your account.  Are you wanting to use Square on additional devices?  all you have to do is download the Square POS app and log in with your email and password and all your items and information will download from Square's Cloud servers.
