Location Codes for Courier and Parcel Companies
A look at how couriers and parcel carriers can use exact location codes for last-mile accuracy, driver handoffs and fewer re-delivery attempts.
Updated 14 October 2026 · 2 min read
For a courier company the most expensive kilometre is the last one. A parcel may cross a country on a pallet for a small cost per item, and then lose that margin in a failed delivery attempt at a door nobody could find. An exact-location code helps with that single stretch.
Where codes help a carrier
Hub sorting works well with official postal codes and routing tables. The problem begins once a driver is in the delivery area with a stack of parcels. A short code tied to a 3 m by 3 m cell tells the driver the actual point, not the neighbourhood. It also survives being copied by phone, written on a label by hand or passed in a message, which long free-text addresses often do not.
Typical uses
- Label field. Print the code, or a link of the form upcs.io followed by the code, beside the written address so the driver can open the pin.
- Driver app. Show the pin and a directions link in the stop list.
- Re-delivery. When a first attempt fails, the recipient can drop a new pin where the parcel should go instead.
- Dispute resolution. The saved code shows where a delivery was supposed to take place.
How data reaches you
Shippers who integrate with UPCS get the code as a plain string in the order data. You can resolve it to coordinates through the lookup endpoint with an API key on the server, as the API documentation describes, or let drivers open the public lookup page. Keep the key out of driver apps; resolve on your own backend instead.
Cautions for carriers
- A code does not carry a recipient's unit number, so retain existing address fields.
- Coverage is limited to the countries UPCS supports, so cross-border routes need a fallback.
- Treat the code as data supplied by the sender, who may have placed the pin imprecisely. Drivers should still be able to call the recipient.
Carriers that deliver for marketplaces can also read the page on online marketplaces, and the page on freight and trucking covers the heavy-vehicle side of the same problem. Partner accounts and keys are managed through the partner page.
Frequently asked questions
Do carriers need to change their sorting systems to use a code?
No. Sorting can keep using postal codes and addresses. The UPCS code is an additional field that matters mostly at the last mile.
