Expanding a list to repeat values based on another column

Hi,

I have a list of addresses and names.

Down one side I have numbers which correspond to properties on another worksheet. Each number appears at least 3 times. On the same page is another column of the same numbers, which don't repeat. I would like to take the suburb name from next to the non repeating numbers and populate the column next to the corresponding numbers which repeat themselves.

Is this possible?

Let me know if I didn't make sense and I'll try and clarify.

Thanks so much
Ryan
