Every year, millions of Americans and businesses change their addresses—and the USPS requires mailers to keep up. The Move Update standard ensures that all bulk and First-Class mail uses the most current recipient addresses. Failing to comply can result in returned mail, wasted postage, or even loss of USPS mailing privileges. This guide explains how to meet Move Update requirements and keep your lists accurate for every mailing.

Sending bulk mail offers major cost savings, but only if your campaign meets USPS compliance requirements. The United States Postal Service has strict standards for addressing, sorting, labeling, and postage—designed to ensure mail moves efficiently through the system.

Mailing at scale can be expensive, but USPS bulk mailing discounts make it more affordable for businesses sending large batches of postcards, flyers, or letters. When you qualify for bulk rates, each piece costs less to send—often saving 20–40% compared to standard postage.
