Octoship puts 550+ shipping services from USPS, UPS, FedEx, DHL Express and international postal carriers like Canada Post, Royal Mail and Australia Post into a single rate list. That's a lot of choice — and the best part is you don't have to memorize any of it. Enter the package once and Octoship sorts every eligible service by cheapest, fastest or best value. This guide explains why a given carrier tends to win, so the rate list never surprises you.

The short version

CarrierUsually best forWatch out for
USPSLight parcels (under ~3 lb), residential delivery, PO Boxes and APO/FPO/DPOSlower and less detailed tracking internationally; duties are always paid by the recipient
UPSHeavier boxes (5 lb+), business addresses, guaranteed air servicesResidential and dimensional-weight surcharges on big, light boxes
FedExHeavier boxes, residential Ground delivery, time-definite ExpressResidential surcharges; dim weight on every package
DHL ExpressFast international delivery, especially to Europe and Asia; prepaid duties (DDP)International only from the US; priced on dim weight, so small boxes win
Local postal carriersShipping from Canada, the UK or Australia, and low-cost delivery inside those countriesAvailability depends on your ship-from address
Rules of thumb, not guarantees. Rates depend on weight, size, distance and destination — always compare.

Domestic: by package size

Under 1 lb

USPS Ground Advantage wins almost every time. It prices by the ounce under a pound, while UPS and FedEx round up to the next whole pound. For non-urgent orders, FedEx Ground Economy is sometimes competitive too — see FedEx Ground Economy.

1–5 lb

This is where it gets interesting. USPS is often cheapest for short distances and small boxes; UPS Ground and FedEx Home Delivery start winning for longer distances and denser boxes. Compare every time — the winner can change with a single zone.

5 lb and up

UPS Ground and FedEx Ground / Home Delivery usually take this weight class. Both carry up to 150 lb, and their per-pound pricing climbs more slowly than USPS for heavy boxes. Business deliveries skip the residential surcharge, which makes them even better value.

Domestic: by speed

DHL Express doesn't carry domestic US-to-US shipments, so it isn't in this table.

UPS and FedEx air services are time-definite — they commit to a delivery day and often a time. If a guaranteed service is late, you may be eligible for a refund of the shipping charges (exclusions apply, especially during peak season and severe weather).

International

Octoship ships to 220+ countries and territories. Your choice comes down to postal versus courier:

  • Postal (USPS international, Canada Post, Royal Mail, Australia Post…): cheapest for small, light packages. Slower, tracking can go quiet mid-journey, and the recipient pays any duties on delivery (DDU).
  • Courier (DHL Express, FedEx International, UPS Worldwide): door-to-door tracking, delivery in a few business days to most major markets, and the option to prepay duties and taxes (DDP) so your customer owes nothing at the door.

For packages over a couple of pounds, couriers are often closer in price to postal services than people expect — especially once you include the cost of refused packages and support tickets about surprise fees. See DHL Express for international shipments for when DHL tends to win.

Other things that tip the scales

  • PO Boxes and military addresses — USPS only. Other carriers are hidden automatically.
  • Saturday delivery — USPS delivers Saturdays as standard; FedEx Home Delivery and UPS Ground include Saturday in many areas.
  • Pickups — every major carrier can collect from your door. See scheduling a carrier pickup.
  • Your own negotiated rates — if you have a UPS, FedEx or DHL Express account, connect it and Octoship compares your rates against ours.
  • Your customers' expectations — a recognizable courier and a fast tracking page can matter as much as the price.
Every carrier in one list. Sort by cheapest, fastest or best value.
