Q: Does FedEx deliver to post office locations? → A: Yes, FedEx delivers to post offices through FedEx Ground Economy (formerly SmartPost), which partners with USPS for final delivery to PO Boxes and post office locations nationwide. This service costs up to 20% less than standard FedEx Ground for lightweight residential deliveries as of January 2026.
FedEx Ground Economy represents a hybrid shipping solution where FedEx handles the long-distance transportation while USPS completes the final delivery to post offices. This partnership allows FedEx to reach over 160 million addresses nationwide, including remote areas that would be expensive for traditional carriers to serve directly.

How Does FedEx Ground Economy Deliver to Post Offices?
FedEx Ground Economy uses a two-stage delivery process to reach post office locations. FedEx handles the initial transportation from origin to the destination postal facility, then USPS takes over for the final delivery to PO Boxes or general delivery addresses.
This hybrid model allows packages to be delivered to traditional PO Boxes that standard FedEx services cannot reach. The service accepts packages up to 70 pounds and 130 inches in length plus girth, making it suitable for most small business and ecommerce shipments.
Package Size and Weight Restrictions
To qualify for post office delivery through FedEx Ground Economy, packages must meet specific criteria:
- Maximum weight: 70 pounds
- Maximum dimensions: 130 inches (length + girth combined)
- PO Box size limits: Packages larger than 12″ x 10″ x 12″ or heavier than 35 pounds are held at the post office for customer pickup
- Most common shipments: Weigh less than 10 pounds, ideal for clothing, accessories, books, and small consumer goods
Coverage Areas in 2026
As of January 2026, FedEx Ground Economy expanded its coverage to include Hawaii, Alaska, and U.S. territories — previously limited to the continental United States. This expansion increases the service’s accessibility for businesses shipping to remote locations where traditional express services are cost-prohibitive. Learn more about FedEx shipping to Hawaii for detailed rate and time information.
What Are FedEx Ground Economy Delivery Times to Post Offices?
FedEx Ground Economy delivers packages to post offices in 2–7 business days across the continental United States, with an average transit time of 4 days. This longer delivery window reflects the two-stage process and makes the service unsuitable for time-sensitive shipments.
The service includes Saturday delivery at no additional charge, which can be convenient for recipients who work during standard postal hours. However, the exact delivery day within the 2–7 day window is not guaranteed, making it a cost-over-speed shipping option.

FAQ: Does FedEx Deliver to Post Office
Can FedEx deliver a package to a PO Box or post office?
Yes — through FedEx Ground Economy (formerly SmartPost), FedEx handles the long-haul transport and hands the parcel to USPS for final delivery to PO Boxes and post office addresses. Standard FedEx Ground and Express do not deliver to PO Boxes.
Why FedEx Can’t Deliver to a USPS PO Box
FedEx generally cannot deliver to a USPS PO Box, and the reason is structural rather than a matter of policy preference. PO Boxes are locked compartments inside Post Office facilities that only the Postal Service can physically access; a FedEx courier has no way to open one and place a package inside. FedEx delivers to physical street addresses where a driver can hand off or leave a parcel, so a shipment addressed to a bare PO Box has nowhere for FedEx to complete delivery. This is why an order shipped via FedEx to a PO Box typically stalls or gets returned rather than delivered.
The Exception: FedEx’s USPS Handoff
There is one genuine exception. FedEx’s economy service that hands the final leg to USPS — the offering historically known as SmartPost and now part of FedEx Ground Economy — can reach a PO Box, because the last mile is actually performed by the Postal Service. FedEx moves the parcel most of the way and injects it into the USPS network for final delivery, and USPS can deposit it in the box it owns. So whether a FedEx-labeled package can hit a PO Box depends entirely on the service level: a direct FedEx Express or Ground shipment cannot, while a USPS-handoff economy service can.
Getting a FedEx Package When You Only Have a PO Box
If a shipper insists on FedEx and you only have a PO Box, a few workarounds exist. Many Post Offices offer Street Addressing, which lets you use the Post Office’s physical street address followed by your box number as a unit — a format FedEx can deliver to because it resolves to a real street location. Alternatively, you can have the shipment sent to a FedEx Hold at Location for pickup at a staffed FedEx location, or use a private mailbox at a shipping store, which provides a true street address that accepts all carriers. Each of these gives FedEx a deliverable physical destination instead of an inaccessible postal box.
FedEx vs. USPS Box Options
The cleanest mental model is to match the carrier to the box. If your only receiving point is a USPS PO Box, USPS itself is the frictionless choice, since the box and the carrier are the same organization. If you frequently receive from all carriers, a private mailbox that provides a street address avoids the PO Box limitation entirely. Knowing this in advance prevents the common mistake of buying something that ships FedEx-only and routing it to a PO Box it can never reach.
FedEx Hold at Location as a PO Box Alternative
Because FedEx cannot deliver to a USPS PO Box, the practical substitute is FedEx Hold at Location, which lets a package be held for pickup at a staffed FedEx point instead of a home address. Recipients can redirect an in-transit shipment to a FedEx Office, a participating Walgreens or Dollar General, or a FedEx Ship Center, then collect it with a photo ID. This gives someone who relies on a PO Box for mail a way to still receive FedEx parcels — you ship to the recipient’s street-address-based Hold at Location point rather than trying to force a PO Box onto a FedEx label, which the system will reject or flag for correction.
What Happens When FedEx Is Addressed to a PO Box
If a FedEx label is created with a PO Box as the destination, the shipment does not simply fail silently. It typically triggers an address-correction step: FedEx attempts to reach the shipper or recipient for a physical street address, which delays delivery and can incur an address-correction fee. For the one FedEx service that does reach PO Boxes — FedEx Ground Economy, which hands the final leg to USPS — the PO Box works because USPS completes delivery. Knowing which service is on the label tells you whether a PO Box address is a problem or perfectly fine, so check the service level before assuming a PO Box shipment will bounce.
Rural Post Offices and the USPS Final-Mile Handoff
In rural areas where FedEx does not run its own residential routes efficiently, FedEx Ground Economy leans heavily on the USPS handoff, injecting parcels into the local post office for delivery by the mail carrier who already services that route daily. This is why a rural recipient often sees the final delivery scan come from USPS even though the shipper chose FedEx. The upside is reliable reach into addresses FedEx trucks rarely visit; the tradeoff is slower transit, because the package waits for the USPS induction and the standard mail delivery cadence rather than a dedicated FedEx stop.
Choosing Between a PO Box and a Street Address for FedEx
If you know a shipment might come via FedEx, the safest choice is to give the sender a physical street address rather than a PO Box, because only the USPS-handoff service reaches a box and standard FedEx services do not. For recipients who rely on a PO Box for privacy or because home delivery is unreliable, a good middle path is a street-addressed pickup point — a FedEx Hold at Location site or a real street address where someone can receive parcels. Some people also use a USPS Street Addressing option, which lets a PO Box be written as a street address so both USPS and private carriers can deliver to the same post office box location. Confirming which addressing the recipient’s post office supports prevents a FedEx parcel from bouncing back for a bad address.
