Understanding How Post Office Address Changes Work

When you move to a new home, the U.S. Postal Service needs to know your updated address so mail reaches you correctly. An address change, also called a change of address or COA, is a formal notification that tells postal carriers where to deliver your mail going forward. This process is managed by the United States Postal Service, a federal agency responsible for delivering mail to all residential and business addresses across the country.

The postal service processes millions of address changes each year. According to USPS data, the agency handles approximately 40 million address changes annually, with the highest volume occurring during summer months when people typically relocate. Understanding how this system works helps you avoid mail delivery problems that can affect important documents, bills, and correspondence.

When you submit an address change, the USPS maintains your forwarding information in a database. Mail carriers use this information to redirect pieces addressed to your old location to your new one. The forwarding service typically works for 12 months, though you can renew it if needed. During the forwarding period, mail sent to your previous address will be physically forwarded to your new location, usually within 3 to 5 business days after processing.

Different types of moves require different approaches. A permanent address change applies when you're relocating long-term to a new home. A temporary change works for situations like seasonal moves or extended travel. Business address changes follow similar procedures but may involve additional steps if multiple employees receive mail at your company location. Understanding which type of change applies to your situation helps you complete the process correctly the first time.

Practical Takeaway: Recognize that an address change is a communication system connecting your old and new mailing locations. This foundation helps you understand why timing and accuracy matter when you notify the postal service of your move.

Step-by-Step Process for Changing Your Address

The USPS offers multiple methods for submitting an address change, each with different timeframes and requirements. The online method through USPS.com is the most common approach, used by millions of people annually. The process typically takes 10 to 15 minutes and requires basic information about your old address, new address, and the date you want the change to begin.

To change your address online, visit the USPS Change of Address website directly. You'll need to provide your current mailing address, new mailing address, and the effective date for the change. The USPS will ask whether this is a permanent or temporary change. For permanent moves, you select the date you're moving. For temporary changes, you specify both a start date and an end date. You'll also confirm your identity through the system, which may involve answering security questions based on your personal information.

After completing the online form, you'll receive a confirmation page showing your address change request has been received. The USPS processes online requests within one business day. You should see the change take effect shortly after processing. Keep your confirmation number and email confirmation, as these documents prove you submitted the change if questions arise later.

If you prefer in-person methods, you can visit your local Post Office and complete Form 3575, which is the official address change form. A postal employee will help you fill out the form and answer questions about your move. This method takes longer to process—typically 7 to 10 business days—but some people find it helpful to speak with someone directly. You can also mail a completed Form 3575 to your local Post Office, though this takes the longest to process.

For businesses with multiple employees, USPS offers a bulk address change service. Companies moving offices or relocating can submit address changes for the entire business location. This requires a company representative to submit the change, and the postal service will update all mail delivery for that location.

Practical Takeaway: Choose the method that fits your timeline. Online submission is fastest if you can act within a few days of knowing your move date. In-person visits work if you have questions or prefer to speak with someone directly. Plan to submit your change at least one week before your move date to allow processing time.

Information About What Mail Gets Forwarded

Not all mail automatically forwards to your new address. Understanding which types of mail are covered by forwarding and which require manual notification helps you stay connected to important services. First-class mail, which includes standard letters and bills, will forward to your new address. This covers the majority of personal correspondence you receive, such as credit card bills, insurance notices, and letters from friends and family.

Periodicals like newspapers and magazines do not automatically forward. You need to contact each publication individually with your new address. Many publications have online account settings where you can update your mailing address yourself. If you subscribe to several publications, make a list and systematically update each one. Most publications update addresses within 2 to 4 weeks of your notification.

Packages and parcels sent via Priority Mail, Priority Mail Express, or other USPS services will forward if they arrive after your address change takes effect. However, the forwarding time for packages is the same as letters—typically 3 to 5 business days. If someone sends you a package before you notify the postal service, it may arrive at your old address before the carrier knows to forward it.

Government mail has specific rules about forwarding. Social Security statements, tax documents, and other federal mail will forward under your address change. However, some government agencies maintain their own mailing lists separate from the postal service system. You may need to contact agencies directly—such as the IRS, Social Security Administration, or your state's tax agency—to update your address with them specifically. This is especially important for tax documents and benefit statements.

Bank and financial institution mail forwards like regular first-class mail. However, it's still wise to update your address directly with your banks, credit card companies, and investment firms. This ensures they have your current information in their systems and can contact you about account issues. It typically takes financial institutions 2 to 5 business days to update their address records after you contact them.

Court documents, jury duty notices, and other legal mail will forward through the postal service system, but you should also update any court records with your new address directly if possible. Many courts allow you to update your address through their websites or by calling the court clerk's office.

Practical Takeaway: Create a checklist of important accounts and services—banks, insurance companies, employers, subscription services—and contact them directly with your new address. Don't rely solely on postal forwarding for critical mail. This extra step prevents missed bills, insurance policy changes, or other important updates.

Common Address Change Mistakes and How to Avoid Them

One of the most frequent mistakes people make is submitting an address change with the wrong effective date. If you indicate a move date that's several weeks away but submit the change immediately, mail will stop being delivered to your old address before you've actually moved. This creates a gap where important mail may be lost. Plan to submit your change no more than one week before your actual move date. This gives the postal service time to process it while still maintaining normal delivery at your old address during your transition.

Another common error is providing incomplete or inaccurate address information. Apartment numbers, unit numbers, or suite designations must be included exactly as they appear on mail you receive at that location. Partial address information can cause the forwarding system to malfunction. Before submitting your change, look at a piece of mail you currently receive and use that format exactly. This includes ZIP codes, which must be correct for the postal system to route your change properly.

Many people forget to update their address with individual companies and organizations, relying entirely on postal forwarding. While forwarding works for most mail, some organizations use mailing lists that operate separately from the postal service system. Subscription services, medical offices, and insurance companies sometimes maintain their own mailing databases. If you only update your address with the postal service, these organizations may still send mail to your old address, and it might not forward correctly or might get lost in the process.

Changing your address too far in advance is another mistake. If you submit an address change 30 days before your move, the postal service will begin forwarding mail that whole time, even though you're still at your old address and need mail delivered there. Forwarding services have a 12-month limit, and unnecessary forwarding time reduces the period available if you need to extend it later.

People sometimes overlook updating their address with their employer, especially if they receive paychecks, W-2 forms, or benefits information by mail. This can cause important tax
