Matching two data sets and return its position in one of the sets.

I have two excel data sets with the following information

Old Contact info: School name, address, city, postal code, province, phone number

New contact info: ID NUMBER, School name, address, city, postal code, province, phone number

I would like to get the ID number for all of the new contact information and match it next to the old contact info based on school name, city, province, and the postal code- but I would like it so that the text does not have to be an exact match for the school name. So basically next to the old school information I would like a column that shows the ID NUMBER for the data that matches from the new contact info (its location) plus all the information from that new contact.

That way I will have a blank cell for any old school contact info that is not in the new list (meaning it closed or moved addresses).

I have very little experience with MATLAB so any help getting started would be great.
