The USPS stands for United States Postal Service. It is an independent concern of the government of United States. The USPS is a delivery service provider and deals with billions of delivery parcels every week. The USPS system works by delivering items to the recipients on the basis of an address. This address contains unique identifying information like name, street, city, state, and postal code like the five-digit ZIP Code that represents a geographical area.



Most Delivery service providers like USPS charge a certain amount as shipping fees to senders. There are quite a lot of methods available which allow a sender to prepare the mail in a better way so as to get a discount on the shipping fee. One of the ways is to pre-code the mail with a bar code, and send it to a to a USPS mail processing facility. The USPS will now use automated mail processing tools to apply an 11-digit delivery point bar code on every mail for identifying each address.

Mailers can also bar-code the mails themselves. For this they need to use address validation software for validating an address and then bar-code each piece of mail. Validating addresses using USPS validating software means confirming that a particular address is available for delivery by the USPS. If the mailer now sends mail to that particular address, the item is sure to get delivered and it will not be returned to sender or destroyed.

There are many companies providing address validation software. They have an extensive product line for providing the full range of postal processing, mail data and Intelligent Mail solutions.

The MaxCASS software can clean up your files. It updates the customers' database with the current and correct information about addresses available from the USPS. The MaxPresort is used for presorting mails of different types like letters, NFMs, flats, parcels and in different USPS classes. The MaxMover is used for providing users with the ability of automatic updates of the original records with the new address information. The address validation software is called Address Verifier.
