Israel Post has your number. All 7 digits of it
Despite having rather fewer people than China, Israel is switching to a rather more complicated 7-digit postal code system.
Addresses, complete with zip codes, were invented in the Ukraine 80 years ago. Now you know. The idea was to represent geographic areas with letters and numbers to make mail distribution more efficient. Or as the Israel Postal Company explains on its website, "A postal code is a number that is an inseparable part of an address that helps route mail to its destination."
