Compare Shipping Companies: USPS, UPS, FedEx, DHL
Start here to pick an international carrier: quick decisions, head-to-head pages and the facts that matter
The quick rule: use USPS for letters and small non-urgent parcels, and a courier when you have a deadline, a heavy parcel or a commercial shipment. Among couriers, compare UPS, FedEx and DHL on real prices for your route. None of them is simply the best, and most claims that one is "fastest" are not backed by public data.
Answer Three Questions
Does it have a deadline?
Under a week: courier express. One to two weeks: Priority Mail International or a deferred courier service. No deadline: First-Class Package International for light items.
How big is it?
Letter: USPS only. Under 4 lb: usually USPS. Heavy and compact: USPS Flat Rate. Bulky and light: check DIM weight. Over 70 lb: UPS, FedEx or DHL.
Where is it going?
Canada or Mexico: consider road service. Hard customs destinations: couriers usually handle them better. Check country guides and, for USPS, current suspensions.

Which Carrier Is Most Common Where?
This affects drop-off points and returns more than transit time:
- United States: USPS, UPS, FedEx and Amazon carry most domestic parcels. DHL Express focuses on international shipments, with only a limited domestic product.
- Germany: DHL is by far the largest parcel carrier, then Hermes, DPD and UPS on third-party estimates. UPS is more common than FedEx for everyday parcels. See UPS vs FedEx.
- Everywhere else: USPS items are delivered by the national post, such as Royal Mail, Japan Post or Canada Post. Couriers deliver with their own staff or local partners, depending on the postcode.
