Does first class mail deliver on sundays

In the United States, the United States Postal Service (USPS) typically does not deliver First Class Mail on Sundays, except for in certain circumstances.

According to the USPS website, First Class Mail is delivered Monday through Saturday, but not on Sundays. This is because the USPS observes Sunday as a day of rest and does not operate its delivery services on that day.

However, there are some exceptions:

1. Priority Mail: Priority Mail is a faster and more expensive service that is delivered Monday through Saturday, including Sundays.
2. Parcel Post: Parcel Post is a slower and more affordable service that is delivered Monday through Saturday, including Sundays.
3. Some rural areas: In some rural areas, the USPS may deliver mail on Sundays, but this is not a standard practice.
4. Special events: During special events, such as holidays or natural disasters, the USPS may temporarily suspend its Sunday delivery schedule.

It's worth noting that while the USPS does not deliver First Class Mail on Sundays, it may still accept mail and packages on Sundays for delivery on Monday or later.

If you're unsure about the delivery schedule for a specific package or mail item, you can contact your local post office or check the USPS website for more information.
