Someone Else Getting Your Mail? How to Fix Misdelivered Mail (2025)

How to fix mail being delivered to the wrong person

Is This a Big Deal?

Occasional misdelivery happens—carriers make mistakes, especially substitutes on unfamiliar routes. This is usually easy to fix.

Consistent misdelivery is more concerning and could indicate a systemic issue or, in rare cases, fraudulent mail forwarding. If your mail is regularly going elsewhere, take action immediately.

Discovering that someone else is receiving your mail is concerning—it means important documents, bills, and sensitive information might be in the wrong hands. Whether your mail is going to the wrong address or a previous resident's forwarding is affecting your delivery, this guide explains why it happens and how to fix it quickly.

Common Causes of Misdelivered Mail

1. Similar Addresses

123 Main St vs 123 Main Ave, or Apt 1 vs Apt 11. Carriers can mix up similar-looking addresses, especially with substitute carriers.

2. Your Name Not on Mailbox

If your name isn't clearly displayed, carriers may assume you don't live there and return mail or deliver to a different unit.

3. Incorrect Address in Sender's Records

Banks, utilities, and companies may have typos or old addresses in their systems, sending your mail elsewhere.

4. Fraudulent Mail Forwarding

In rare cases, someone may have fraudulently set up mail forwarding from your address. This is identity theft—report immediately.
