| Your benchmark for measuring will be the more famous (or infamous) zip codes such as 90210 (Beverly Hills) and 10005 (Wall Street) among a few others.
Lesser known are simply that, lesser known and perhaps only represent numbers. So I am really not sure what or how the market will value these. Try to talk someone out of 90210 and see what they want for a domain in any extension.
Plus, China zip codes are mostly NNNNNN (six).
