ZIP code in edit profile page not display

[clowthu]

Hi, 

I have spotify account is linked with my facebook account. For the purpose family package, Postal code must be required. I saw zip code in edit profile information, zip code is empty so I want to change it but it can't..

I try to fill zipcode in facebook, so I go to facebook page and then go to about->Contact and Basic info->address->edit. Zip code is already filled with ****. I try save address and then refresh edit profile spotify information. It's still same, zip code is empty..

How to fill it ?
