This will depend greatly on what information is in your addresspoint file and in the missing addresses. I presume you're in the UK Possible solutions: Map the addresspoint table and then match this to the addresses graphically Match the addresses using some portion of the data which is in both files, eg road name plus house number There are commercial solutions: for a small sample the Post Office's web site can be used for free https://www.postoffice.co.uk/portal/po/postcodefinder;jsessionid=HI2GPAMJEQCLMCRAZRYUOSQKEDGHEQ2K?pageId=pol_login&catId=7800129&_requestid=25902&cs=1 "Angela.

I have at hand a file called Addresspoint. Any ideas how I can use this and find the postcodes?
