Why Hasn't My First Class Mail Been Delivered Yet?

The estimated delivery time for First-Class Mail® is 2 to 4 postal business days, but does not provide the benefit of a guarantee like Express Mail® service offers. 

If expected First Class Mail® or Priority Mail® has not arrived within 5 postal business days from its date of mailing, you can:

Call 1-800-ASK-USPS (1-800-275-8777) where a customer service representative will document your concern, OR
Visit the Postal Inspection Service website and complete a mail loss report.

Please note that with a mail loss filing, you will not automatically receive a response. If the item(s) is located it will be returned to you.
