I am filing a joint return where the individuals live in NY, but the wife works in NJ. The husband works in NY. The husband also has an investment in a partnership that has a foreign address. When allocating income to NJ only the wife's wages are taxable in NJ. The NJ return is picking up the information from the K-1, but only the name and address , I am having a problem in entering the Zip Code . It tells me it is not a valid code. The address is George Town, Grand Cayman, CJ KY1-9005. 

Can you help me.
