Zip code validation is the process of verifying a postal address by checking its ZIP code against the USPS’s official address database. It is a key part of any direct mail application.

Business Applications That Need Zip Code Validation

Direct mail is a crucial part of any business’s marketing and sales efforts. It can be used to send mailers, newsletters, and other communications. However, sending mail to the wrong address can lead to costly errors that cost your business time and money.

Resource Wastage

The most obvious way in which a business can waste resources on a mailing list is by wasting paper and ink. These resources can be expensive, and they are necessary for a direct mail piece to be effective.

Fortunately, businesses can save money on this resource wastage by using a yup zip code validation API to ensure that the addresses on their lists are accurate and deliverable. This will reduce the number of returned mailings, and help them save on postage costs.

While a free tool like USPS’s ZIP code lookup service may be available, there are also more advanced tools that can be used for this purpose. These include third-party solutions that offer more functionality than the free USPS solution. These solutions are more developer-friendly and can be customized to meet your needs.
