What is the purpose of PS Form 3849?

The purpose of PS Form 3849 is to notify customers about pickup opportunities for their mail or packages that could not be delivered. When a postal carrier is unable to deliver an item, typically due to the recipient not being home, this form is left at the delivery address. It informs the customer that their item is available for pickup at their local post office and provides details such as the location and time for retrieval. This process enhances customer service, ensuring that recipients are aware of how to receive their mail even if direct delivery could not be completed.

While other forms may be used for documentation of addresses, tracking mail, or recording signatures, those functions are not the primary purpose of PS Form 3849.
