Mail class and postage type:

First Class and Standard (Marketing) Mail have different delivery times, with First Class Mail generally arriving faster.

Seasonal and operational factors

Mail delivery times can be affected by holidays, severe weather, and other unexpected events.

USPS online tools and resources for calculating mail delivery time

The USPS website offers several resources to help estimate mail delivery times, such as the USPS Service Standards Map and the PostalPro Business Calculator. These tools can provide more accurate delivery time estimates based on zip codes and mail class.
