I am trying to geocode a large xl file with state zip codes. I have a file created fromof the us_zip tbl that came with the software last year to geocode to. When I try to geocode the file only about .5% of the data in the spreadsheet is recognized. I have checked the zip codes in the spreadsheets with the post office and most are PO boxes. Is there a file that contains all of these codes to reference to or another way to get mapinfo to recognize them? The file is too large to go one by one through manually and change all the po's to another zip. Please help! Renaye O'Mahony
