What Is Address Cleansing and Verification?

When your shipping labels contain typos, incorrect ZIP codes, or non-standard state abbreviations, delivery rates can decline and postage may be wasted if your mail is returned as undeliverable. Address cleansing and verification help ensure that your delivery addresses are formatted to the U.S. Postal Service’s preferred specifications and only include addresses that the USPS delivers to.

How Address Cleansing and Verification Works

CASS-certified address cleansing and verification software will check your shipping address against the USPS database before printing your shipping label. If there is a needed correction, the software will suggest the USPS-approved address.

Example of Address with Misspellings and Bad Data

The address below contains a couple of misspellings, an improper abbreviation, and an incomplete ZIP code:

John Smith
11950 Salam Drive
Granada Hils, Ca 91333

Example of Address After Cleansing and Verification

Once the address has been cleaned using verification software, the address becomes:

John Smith
11950 Salem Dr
Granada Hills CA 91344-2347
