Some Factors Affecting USPS Delivery Time

While each service has its expected delivery duration, these durations are not guaranteed. Delivery may take less time than you expect or more time! 

Some factors that affect USPS delivery times are; 

  • The fluctuation of mail volumes every day
  • Traffic
  • Staff fluctuations
  • Natural disasters
  • Change in a carrier route and some other factors. 

Also, be aware that delivery time varies from one class of mail to another. One could mistake one service for another and, in so doing, experience a false delay. 

Mails and packages may take up to 5 days or more from the day of expected delivery.

Before contacting USPS for late deliveries, be sure to check the mail delivery standards or contact the shipper for more information. 

You may also track your delivery by going to the USPS Tracking page and inputting your tracking number for your item. 

Keep regularly checking for information about your package.

You should contact the shipper if you do not have your tracking number. You should also get your mailer if the delay is not from the shipper. The mailer is to provide the tracking number or help you track the item.

Finally, visit your local Post Office to address your concerns. 


You should expect your packages between 3 – 6 working days. In a situation of delayed delivery, be sure first to contact the appropriate authorities before USPS. 

Many factors may affect the delivery time, but do not fret. Also, be sure to package your item well for shipping.
