> Comparing Ideal Postcodes, OS Places API, Loqate and Chimnie for address-to-UPRN lookup

 

If you have a UK address and need to find the corresponding **Unique Property Reference Number (UPRN)**, there are several ways to do it.

Some of the top UPRN solution providers include Ideal Postcodes, Ordnance Survey, Loqate and Chimnie, but they are designed for different workflows.

 

TL;DR

- **Ideal Postcodes** returns a UPRN with every matched UK address at no additional charge and supports address autocomplete, postcode lookup, cleansing and bulk matching.
- **OS Places API** provides direct access to authoritative AddressBase Premium data, including UPRNs, but has additional access and licensing requirements.
- **Loqate** provides UPRNs through its Geo+ premium UK dataset alongside address verification and geocodes.
- **Chimnie** combines provides UPRN and other property specific data such as EPC, valuation, and risk.

 

## How do I get UPRN data from a UK address?

You can get a [Unique Property Reference Number](https://ideal-postcodes.co.uk/guides/uprn) by using an address lookup or property-data service that matches a UK address to its Unique Property Reference Number. Some services, such as Ideal Postcodes, return the UPRN alongside a validated address, while others provide it as part of broader geospatial or property datasets.

 

## How Do UPRN Services Compare?

 

| **Service** | **How you get the UPRN** | **Wider functionality** | **Pricing approach** |
| --- | --- | --- | --- |
| Ideal Postcodes | UPRN included with matched UK address records | Address autocomplete, postcode lookup, cleansing, geocodes and bulk matching | Pay as you go; UPRN included at no extra cost |
| **OS Places API** | Search an address or postcode and receive AddressBase records containing UPRNs | Geocoding, reverse geocoding and detailed authoritative address data | Subject to OS access and licensing requirements |
| **Loqate** | Add UPRN through the Geo+ UK dataset | Address capture, verification, geocodes and wider data enrichment | Paid address services; Geo+ is an additional premium dataset |
| **Chimnie** | Search for a property by address and work with UPRN-based property records | Property values, EPCs, risks, planning data and other property attributes | Address-searchable Plus tier for a cost per property |

 

 

## How Does Ideal Postcodes offer UPRN Data?

**Ideal Postcodes can return the corresponding UPRN whenever a UK address is successfully retrieved.**

That means the UPRN can be captured at the same point as the address rather than requiring a separate property lookup.

UPRNs are included with [UK address results](https://ideal-postcodes.co.uk/uprn) alongside the formatted postal address and property-level geocodes. Ideal Postcodes supports several ways of getting there:

- address autocomplete as a user types
- postcode lookup
- API address search
- address cleansing for existing records
- CSV and bulk address matching

It also works in the opposite direction: if you already have a UPRN, the API can retrieve the associated address using a UPRN filter.

For businesses whose main requirement is **address → UPRN**, this keeps the workflow relatively simple. You can capture or clean the address and receive the identifier in the same process rather than adding a separate property-data service.

## OS Places API

**OS Places API lets developers search authoritative Ordnance Survey address data and obtain the UPRN contained in the matching record.**

The API is based on **AddressBase Premium** and supports searches using:

- full or partial addresses
- postcodes
- UPRNs
- coordinates and geographic areas

Address results can contain the UPRN as well as coordinates, classifications and other detailed AddressBase fields.

This makes OS Places particularly relevant when you need direct access to detailed authoritative addressing and geospatial data, rather than simply adding a UPRN to a customer or property address.

OS Places is a Premium API, and access depends on the relevant OS plan and intended use. Ordnance Survey states that organisations using the data solely for internal business purposes may need to obtain it through an OS Partner. OS Places also cannot be used for bulk queries in the same way as a dedicated batch-cleansing product.

## Loqate

**Loqate provides UPRNs through its Geo+ UK location dataset.**

Geo+ combines Royal Mail PAF data with Ordnance Survey location data and can return:

- UPRN
- UDPRN
- property-level coordinates
- property type
- related property identifiers

Loqate can search using an address and return the UPRN in the resulting record. It can also search in the other direction using an existing UPRN.

The main distinction is that **UPRN is part of an enhanced dataset rather than simply a standard address-capture field**. Loqate describes Geo+ as an additional UK dataset that can be enabled alongside its address services.

## Chimnie

**Chimnie approaches the problem from a property-data perspective rather than primarily as an address-validation service.**

Its Plus product can search properties by address, while its wider platform uses UPRNs to connect each property with additional information.

That can include:

- property characteristics
- EPC and energy data
- sales history
- council tax
- flood and other risk data
- planning applications
- property valuations
- nearby amenities

If your goal is simply to attach a UPRN to an address, much of the additional property intelligence may be unnecessary. If the UPRN is the starting point for underwriting, valuation, property research or risk analysis, that extra data becomes the reason to use it.

## Which Address-to-UPRN Service Is Suited to Which Use Case?

**Ideal Postcodes** is suited to businesses whose primary requirement is to take an address and reliably attach its UPRN. The same service can handle autocomplete, postcode lookup, address cleansing and bulk matching, with UPRN and geocodes included in the UK address lookup price.

**OS Places API** is suited to organisations that need direct access to detailed authoritative Ordnance Survey addressing and geospatial data and are comfortable with its licensing and access model.

**Loqate** is suited to businesses that want to add UPRNs and geospatial identifiers through an enhanced UK dataset, and don’t mind the additional cost.

**Chimnie** is suited to property, insurance, lending and proptech applications where identifying the property is only the first step and the business also needs deeper information about that property's value, characteristics or risks.

## Frequently Asked Questions

Can you find a UPRN from a postcode?

A postcode alone will often contain multiple properties, so it normally isn't enough to identify a single UPRN. A postcode lookup can return the addresses within that postcode, after which the correct property can be selected and its UPRN returned.

Can I add UPRNs to an existing list of addresses?

Yes. Services that support [address cleansing](https://ideal-postcodes.co.uk/address-cleanse) or batch processing can match existing address records and append UPRNs. Ideal Postcodes supports the Cleanse API as well as CSV and bulk UPRN matching.
