Timely and accurate mail delivery is vital to businesses everywhere. When your customers’ addresses contain typos, incorrect ZIP codes or non-standard state abbreviations, delivery rates can decline, time in transit can increase, and often times postage is wasted when mail is returned as undeliverable.  In addition to the money spent on returned postage, deliverability issues can have a huge negative impact on customer service.

But when you’ve got thousands of addresses in your customer database, it’s nearly impossible to manually ensure that each and every one of them is correct and formatted to the USPS’s preferred specifications.  This is where address cleansing software comes into play.

What Is Address Cleansing?

Address cleansing is accomplished by software that compares your addresses to addresses in the USPS database to help you discover any errors or inconsistencies regarding spelling, ZIP codes, or state abbreviations.  Often, the cleansing software will suggest an alternative, much like a spell checker.  Occasionally, the address will be incomprehensible; while this may sound like a bad thing, it is better to catch these mistakes before wasting postage on them.  Here is an example of an address that contains a couple of misspellings, an improper abbreviation and an incorrect ZIP code, as well as some missing information about the street:

John Smith
11950 Salam Dr
Granada Hils, CA 91333

Once the address is cleansed according to the USPS’s standards by fixing the street name, city, and zip, the address becomes:

John Smith
11950 Salem Dr
Granada Hills CA 91344-2347
