Quick answer: For normal residential and commercial parcels, UPS does not deliver on Sunday. UPS's current U.S. weekend-delivery page says UPS delivers Monday through Saturday, and explicitly says there are no deliveries on Sunday. The main exception is UPS Express Critical, which UPS says is available 24/7/365 for urgent shipments.
The old version of this topic overstated Sunday delivery. The cleaner 2026 answer is to separate ordinary UPS parcel service from UPS's urgent exception service.

Does UPS deliver on Sundays?
For standard residential and commercial parcels, no. UPS's current U.S. weekend-delivery page says UPS offers Monday through Saturday delivery service and that there are no deliveries on Sunday.
So if you are asking about a normal UPS package, Sunday should not be the expected delivery day.
Is there any exception?
Yes. UPS says UPS Express Critical is available 24/7/365. That is an urgent, specialized service, not the ordinary parcel-delivery pattern most shoppers are asking about.
So the practical distinction is simple: regular packages are not Sunday deliveries, but urgent critical shipments can have a different service model.
What does this mean for ordinary shoppers?
If you are tracking a normal UPS residential or commercial parcel, plan around Monday through Saturday delivery rather than expecting a routine Sunday arrival. If a shipment is truly time-critical, the relevant exception is Express Critical, not ordinary ground or standard weekend service.
Bottom line
UPS does not normally deliver regular parcels on Sunday in 2026. The main official exception is UPS Express Critical for urgent shipments.
