NS US server zipcode is filled in. Is it asked to be filled in when linking the card?

I have a US server account. I also fill in this when I bind a card. It asks you for the card number. Just fill in 00000. Then you can pay normally when buying games. My single-label visa credit card from China Merchants Bank. In addition, you need to set the location settings in your eshop. Click your avatar account information to see it. I filled in 90008, Los Angeles, California, which is a tax-free state. After setting it up, no tax will be added when buying US server games, so fill it out like this.
