The USPS offers a variety of mail services, including marketing mail and first-class mail. To be eligible for these rates, you must ensure that your address is current and accurate. A postal address checker is a useful tool for this purpose. You can use it to determine whether an address is valid or not and then verify the information using the USPS’s validation services.
USPS addresses are validated against the official address database. If there is no match, the address is invalid and must be updated. A valid address is one with a nine-digit ZIP code. An invalid address will have a “VACANT” label in its address file. If an address is invalid, it may not be deliverable at all.
The USPS website offers an address verification service where you can enter addresses one at a time. However, if you have a large address list, you may want to use a third-party address checker. These services typically allow you to upload your address list in Excel or CSV format. Some of them also offer APIs to make the address verification process even more convenient.
Whether you’re mailing something, an address checker tool is a valuable tool for any business. It can reduce the costs of mailing and speed up delivery. It’s easy to use, too.
