Hong Kong? http://postal-codes.net/hong-kong/ I guess that puts a nail in the zip code part of registration... I wonder then how any other software or website registration handles addresses from Hong Kong? I guess other software do not require/check for a ZIP code field in a HK address? So the interesting thing is how bigmuscle's scripts deal with a null ZIP code input (I suppose he uses a script to automatically generate accounts from the info reported by PayPal) This is what I see in the HTML of my PayPal page shipAddresses["----Unique ID-----] = {"addressee-name": "--my name--", "street-address": "address line 1", "extended-address": "address line 2", "locality": "","region": "","postal-code": "", "country": "香港", "country-code": "HK"};
