Coordinates Alongside Addresses: Why Both Help

An address describes a place in words, while coordinates give an exact point. Learn how the two complement each other and where each falls short.

Updated 14 October 2026 · 3 min read

An address and a pair of coordinates describe the same place in different ways. An address is a human-readable label built from names and numbers. Coordinates are a pair of numbers, latitude and longitude, that identify a point on the Earth's surface.

What an address does well

It is readable and memorable.
It follows social and administrative conventions.
Postal systems, tax offices and businesses are built around it.
It carries meaning: a district, a street, a building.

Where addresses fall short

Several places can share similar addresses.
Buildings may have no number, or streets no name.
Spelling and language variation cause mismatches.
An address points to a building, not to the entrance.

What coordinates do well

They identify one point, with no ambiguity of spelling or language.
They are machine-readable and work with any map or navigation tool.
They can be as precise as the measurement allows.

Where coordinates fall short

Numbers are hard to remember and easy to mistype.
They carry no context such as a street, a floor or an apartment.
A point is not an address: it does not tell you which flat or who to ask for.
Formats vary (decimal degrees, degrees and minutes), which invites confusion.

Using both

The strongest approach is to keep the address for meaning and add a precise location for navigation. A courier reads the address to confirm the recipient and uses the point to arrive at the right door. See exact-location codes for ambiguous addresses.

Where UPCS fits

UPCS turns a point on the map into a short code in the format CC-XXXX-XXXX, where each code stands for a 3 m by 3 m cell, so the same coordinates always give the same code. It is easier to share than a pair of decimals, and the lookup page shows the coordinates behind the code. It is an addition to an address, not a replacement and not an official postal code.

See descriptive addresses and address standardisation explained.

Summary

Addresses give meaning, coordinates give precision. Use both when delivery accuracy matters.

Frequently asked questions

Can coordinates replace an address?

Not for postal use. Postal systems and many services are built on addresses. Coordinates are best used alongside an address, as an extra layer of precision.

What is the difference between latitude and longitude?

Latitude gives a position north or south of the equator, and longitude gives a position east or west of a reference meridian. Together they identify a point on the Earth's surface.
