Why do I have to have my zip code?

Hey there phares288, 

It seems like you would like to know why your zip code is needed when adding a payment method to your Apple ID. That is because your payment method must match the country or region of your Apple ID.

A postcode is part of your mailing address. In the USA it is 5 numbers and is known as a zipcode, e.g, 90210 Other countries may use a combination of letters and numbers, e.g. CV2 LBT. The postcode and address must be valid for the country of the store you are trying to use. You cannot use an address and postcode from one country to activate an account for use in a different country.

Look on a letter you have received or do a web search with the word postcode or zipcode and the address where you live.
