The US Postal Service delivered about 425.3M mail pieces daily in 2021. Unfortunately, some of these letters never got to their destination. They returned to the sender, and the recipient got the note 'No Access to Delivery Location.'
If such a problem occurs regularly, recipients and senders can quickly get frustrated. Delivery problems are particularly devastating for businesses that depend on offline shipments. When they fail to reach the customer, they lose money and suffer from damaged customer relationships.
The good news is there are several ways to fix delivery issues and ensure that your mail always gets to its intended recipient on time. This article explains what happens when a delivery fails and how people and businesses can prevent it.
What Does USPS No Access to Delivery Location Mean?
The USPS no access to delivery location message could have a few meanings. But the general message is that a USPS mail carrier couldn't deliver to the recipient. Often, the carrier may not be able to physically deliver the package to your doorstep because of unavoidable issues such as:
- Force majeure. An obstruction on the road from a tree brought down by extreme weather conditions, making it impossible for the worker to get to your location.
- Blocked access to the house. Inaccessible locations make the mailer unable to reach the recipient's location. A nearby road construction, renovation, or an accident blocking access to your street prevents the USPS from delivery.
- Mailbox issues. A filled, damaged, or inaccessible mailbox can make a solid reason why the recipient receives a USPS delivery failed postcard.
- Locked gate. A locked gate preventing entrance into your home or apartment could also result in a failed delivery.
- An unrestrained pet, usually dogs. Since carriers are strangers, the dog may perceive them as a threat. Hence, the recipient may get a USPS delivery failed message if an untethered dog is roaming on the premises.
- No address. There is also a good chance that the USPS has no record of the mailing address in its database. It's often a widespread cause of a USPS delivery exception.
In the recent past, there have been reports that the USPS did not try to deliver, but they say they did. This may happen on weekends and in rural areas that are more difficult to reach.

Why Won't the USPS Deliver to My Customers' Addresses?
Other than the reasons we just listed, there is also a chance that your customers get the USPS no access to delivery location if they have a problem with their address information.
There are millions of registered addresses in the United States Postal Service, but the records are never static. There are continuous and regular changes of address and new additions all over the country every year.
Suppose your customers live in new homes, streets, or apartments that have not been added to the USPS Address Management System. Then, they will likely get a 'USPS delivery attempted no access to delivery location' postcard.

Troubleshooting USPS Delivery Issues: for Customers and Businesses
If your customers receive regular USPS no access to delivery location postcards or messages, the most important thing to do is to find how to troubleshoot USPS delivery issues.
Here are a few tips for customers and businesses to get started:
Buy a Porch Camera
Porch cameras are a relatively new technology that has grown in demand in the last few years. Initially, they were for security reasons (they still are). However, people also use them to monitor their deliveries to ensure that 'package pirates' aren't hijacking their deliveries.
Also, with a porch camera, your customers can confirm that a USPS mail carrier attempted to make a delivery but failed because the USPS delivery location was not accessible.
