>MelissaData, MyMailList are all garbage. Try USPS if they provide any dll file, I know they do provide service similar to what you are looking for with quarterly updates. I have used a company called 'FirstLogic' in La Crosse which provide Cass certification and Mail Preparation software much better company always on top of any postal changes.

And I use MyMailList and it works great. I've never had mail rejected for a barcode mailing which requires CASS. It prints all necessary documents too. Plus, address are now every two months, not quarterly and the new address CD arrives promptly. MySoftware keeps on top of postal changes rather well. I've never had a problem with them.
