Address Matching - VLOOKUP?

Hello

I am attempting to carry out some address matching and wondered if someone could help.

I have one list of addresses which just contain the house number and street name....and I need to match this against a longer list of addresses which contain the full address (inc. town, county, zip code)

Column A Column B
full address id
Row 1 20 High Street TownName Nottinghamshire NG4 2AA
Row 2 40 Main Road TownName Nottinghamshire NG4 2AA
Row 3 42 High Street Street TownName Nottinghamshire NG4 2AA
Row 4 45 Main Road TownName Nottinghamshire NG4 2AA

So I need to take the address in sheet 1 cell A1 and compare it against a range in a separate sheet - Sheet2!$A$1:$A$4

Column A
short address
Row 1 20 HIGH STREET
Row 2 22 MAIN ROAD
Row 3 45 MAIN ROAD
Row 4 22 HIGH STREET


and if it matches then return a GH in Column B on the first sheet

Any help would save me a lot of time manually matching

Please try at Sheet2 B2

=VLOOKUP(A1&"*",Sheet1!A1:$B$4,2,)

it would be better if you attached a workbook
=IF(ISNUMBER(MATCH(a2&"*",Sheet1!A:A,0)),"GH","")
