The postal code validation for Israel does not work properly.
The postal code validation incorrectly rejects 7 digit postal codes but it accepts 5 digit postal codes.
In 2013, Israel retired 5 digit postal codes and adopted 7 digit postal codes across the board. Please update the Revolut app to use correct validation. See: https://en.wikipedia.org/wiki/Postal_codes_in_Israel
I was unable to add my Israel bank account as a beneficiary because when I entered the Israeli address for that account, the Revolut app claimed that I had entered an invalid postal code. I can assure you that the 7 digit postal code that I entered is very real.
I chopped off the last 2 digits from the postal code (making it 5 digits instead of 7) and the validation passed and accepted it.
