A quick google search for "address verification" will turn up a number of companies that provide services similar to what you are looking for. To use these services our programmers will usually need to export your addresses into a specifically formatted file and then submit to them. The service must return a file which is properly formatted so that the cleaned addresses can be merged back into your BusinessMind database by our programmers. Once you have selected the address verification service you wish to use, contact us at sales@dcit.com for a quote.
