Carrier comparison: USPS, UPS, FedEx
When picking a carrier for the origin-to-destination lane, weight class is what usually decides.
USPS: USPS's flat-rate boxes can be the cheapest option for dense, heavier items in the 5–20 lb range when they fit.
UPS: For B2B shipments on this corridor, UPS Ground is usually the safest combination of price and reliability.
FedEx: FedEx Home Delivery covers residential at competitive rates, particularly for mid-weight (10–25 lb) parcels.

Frequently asked questions
What USPS zone is the St. Louis to Tucson route?
+
This lane is USPS Zone 6 (1,001–1,400 mi). Zones are calculated from the first three digits of each ZIP and represent the distance band between Sectional Center Facilities. Lower zones mean lower rates and faster transit.
Which carrier is best for St. Louis-to-Tucson shipping?
+
There's no single best — it depends on weight, dimensions, and timing. USPS handles light residential cheapest. UPS and FedEx handle heavier commercial best. For volume shippers, the right answer is to use a multi-carrier platform that rate-shops every shipment automatically.
What's the cheapest way to ship from St. Louis to Tucson?
+
For parcels under 5 pounds, USPS Ground Advantage is usually the lowest cost. Above 10 pounds, UPS Ground or FedEx Ground tend to win. The exact answer depends on dimensions, residential vs. commercial delivery, and volume — which is why multi-carrier rate-shopping (rather than picking one carrier upfront) typically saves 20–30%.
How long does shipping from St. Louis to Tucson typically take?
+
Standard ground service runs around 3–4 business days. Two-day and overnight options are available at premium rates if you need a guaranteed delivery date. Holiday periods and severe weather can add 1–2 days, so build in buffer for time-critical shipments.
