What is a UPRN? - Melissa UK
UPRN is a numerical identifier of up to 12 digits assigned to every addressable or spatial locale in Great Britain. The identifier can be placed on any kind of building, such as a house or business premises, or even objects like bus stations, post boxes and so forth.

What is a UPRN?

UPRN stands for Unique Property Reference Number. It is a unique identifier assigned to every addressable location or property in the United Kingdom. The UPRN is used to provide a standardised reference for a specific property, regardless of any changes to the property's address or other details.

The UPRN is a 12-digit numerical code that remains constant throughout the lifespan of a property. It is used by various organisations and government bodies involved in property management, such as local authorities, utility companies, emergency services, and land registries. The UPRN facilitates accurate and efficient communication and data sharing related to properties.

By using the UPRN, different systems and databases can be linked together, allowing for better coordination and integration of information. It helps ensure that data about a property, such as its location, ownership, and services, can be easily accessed and updated across various platforms.

The Allocation of UPRNs

      1. Creation and initial allocation: When a new property or addressable location is created, such as a new building or subdivision, the local authority assigns a UPRN to that property. This initial allocation is often done by the local authority's Geographic Information System (GIS) or Address Management team. The UPRN is assigned based on a unique identifier system established by the local authority or a standardised national scheme.

      2. Data maintenance: Local authorities are responsible for maintaining and updating the UPRN records as changes occur. This includes updating UPRNs when properties undergo modifications, demolitions, or new constructions. The local authority's Address Management team or similar department is typically responsible for this task. They ensure that accurate and up-to-date information is maintained for each property, including changes in addresses, property boundaries, and other relevant details.

      3. Collaboration and data sharing: sharing UPRN data with utility companies, emergency services, land registries, and other stakeholders involved in property management. By sharing consistent UPRN data, it becomes easier to integrate information and coordinate services across different systems.

      4. National coordination: The national coordination of UPRNs and related address management is facilitated by organisations such as GeoPlace in England and Wales, the Improvement Service in Scotland, and Land and Property Services in Northern Ireland. These organisations work closely with local authorities to establish and enforce standards, guidelines, and best practices for UPRN allocation and management across the country.

Overall, the allocation and management of UPRNs involve a collaborative effort between local authorities, national coordinating organisations, and various stakeholders to ensure accurate identification and tracking of properties in the United Kingdom.

The Permanence of UPRNs

UPRNs are intended to provide a permanent and unique identifier for each addressable property in the United Kingdom. The goal is to ensure that the UPRN remains constant throughout the lifespan of a property, regardless of any changes to its address or other details. However, it's important to note that in practice, there can be some instances where UPRNs may change or be subject to updates. Here are a few factors that can influence the permanence of UPRNs:

      1. Address changes: Occasionally, properties undergo address changes due to various reasons such as street renaming, property renumbering, or the creation of new addresses. In such cases, the UPRN associated with a property may need to be updated to reflect the new address.

      2. Property modifications: If significant modifications are made to a property, such as a substantial extension or conversion, it may require reassignment of a new UPRN to accurately represent the changed property. This ensures that the UPRN aligns with the updated characteristics and boundaries of the property.

      3. Property demolitions and new constructions: When a property is demolished and replaced with a new structure, a new UPRN is typically allocated to the newly constructed property. This helps distinguish the new property from the old one and maintains accurate records

      4. Administrative updates: There might be administrative updates or corrections related to UPRNs due to data errors, duplicate entries, or other issues. These updates aim to ensure the accuracy and integrity of the UPRN database.

While the intention is for UPRNs to remain permanent, the practical realities of changes to addresses, property modifications, and administrative requirements may result in updates or changes to UPRNs. However, the objective is always to maintain a consistent and reliable reference number for each property to facilitate effective data management and coordination among different organisations.

UPRNs for Non-Buildings

UPRNs can also be used to identify non-building locations in addition to traditional buildings. Here's how UPRNs are utilised for non-building locations:

      1. Land and open spaces: UPRNs can be assigned to land parcels and open spaces such as parks, recreational areas, vacant lots, and agricultural fields. These UPRNs help in identifying and managing these locations, facilitating land administration, planning, and environmental management.

      2. Infrastructure and utilities: Non-building infrastructure elements like utility substations, telecommunications equipment, power lines, water treatment facilities, and sewage pumping stations can be assigned UPRNs. This enables precise identification and tracking of these infrastructure assets, aiding in maintenance, asset management, and service provision.

      3. Points of interest: UPRNs can be assigned to points of interest (POI) such as tourist attractions, historical sites, landmarks, and commercial areas. Assigning UPRNs to these non-building locations helps with navigation, mapping, tourism, and urban planning, allowing for efficient information retrieval and analysis.

      4. Transportation infrastructure: UPRNs can be used for transportation-related assets like bridges, tunnels, railway stations, bus stops, airports, and seaports. This enables effective management, maintenance, and coordination of transportation infrastructure, supporting travel planning, logistics, and emergency services.

      5. Natural features: UPRNs can be allocated to natural features such as lakes, rivers, mountains, forests, and nature reserves. Assigning UPRNs to these non-building locations aids in environmental management, conservation efforts, and outdoor recreation.

By extending the use of UPRNs beyond buildings, a comprehensive system can be established to uniquely identify and manage various types of locations and assets. This enables better coordination, data integration, and efficient provision of services across different sectors and organisations.

UPRNs for Multiple Addressable Locations

UPRNs are typically assigned to individual addressable locations, which are usually associated with a single property or building. However, there are situations where multiple addressable locations may exist within a larger property or complex. In such cases, specific guidelines and practices may be followed to assign UPRNs. Here's an overview:

      1. Subdivisions or units within a property: In some cases, a single property may contain multiple addressable units or subdivisions—for example, an apartment building or a shopping centre with multiple units or shops. Each individual unit or subdivision within the property can be assigned a unique UPRN to differentiate it from the others. This allows for accurate identification and management of each distinct addressable location within the larger property.

      2. Individual buildings within a complex: In larger property complexes, such as universities, hospitals, or industrial estates, there may be multiple individual buildings with their own addressable locations. In such cases, each building is typically assigned a separate UPRN, enabling precise identification and management of each building within the complex.

      3. Floors or levels within a building: In cases where a building has multiple floors or levels, each floor can be considered an addressable location and assigned a unique UPRN. This can be particularly useful for large office buildings, hotels, or residential complexes.

      4. Sub-addresses or sub-locations: In certain situations, a single addressable location may have sub-addresses or sub-locations within it—for example, a property with multiple entrance points, wings, or sections. In such cases, specific sub-addresses or sub-locations can be assigned unique UPRNs to maintain clarity and accuracy in identification.

The allocation and management of UPRNs for multiple addressable locations within a property or complex aim to provide a comprehensive and precise identification system. This facilitates efficient communication, data management, and service delivery, ensuring that each addressable location within the larger property can be uniquely identified and referenced.

How to Look Up a UPRN

The process of looking up a UPRN can vary depending on the specific system or database used. However, here is a general outline of the steps involved in looking up a UPRN:

      1. Identify the source or database:Determine which source or database contains the UPRN you are looking for.

UPRN Format

A UPRN in the United Kingdom follows a specific format that consists of a 12-digit numerical code. The format of a UPRN is as follows:

NNNNNNNNNNNN

Each "N" represents a digit from 0 to 9, resulting in a 12-digit numerical code. The UPRN is designed to be a unique identifier for each addressable property in the UK, regardless of changes to the property's address or other details. The 12-digit code ensures that each UPRN is distinct and allows for efficient identification and referencing of properties in various databases and systems.

UPRNs and Data Privacy

The use of UPRNs in the context of data privacy primarily revolves around the potential implications associated with the handling and processing of personal information. Here are some considerations:

      1. Address-related information: UPRNs are often linked to address-related information, which can include personal data such as residential addresses or business addresses. As such, organisations using UPRNs must ensure that they handle this data in compliance with relevant data protection laws and regulations, such as the General Data Protection Regulation (GDPR) in the European Union.

      2. Data security: Organisations managing UPRNs should implement appropriate data security measures to protect the confidentiality and integrity of the associated data. This includes measures like encryption, access controls, regular data backups, and robust cybersecurity practices to prevent unauthorized access or data breaches that could compromise personal information.

      3. Data minimisation: Organisations should practice data minimisation when using UPRNs, ensuring that they collect and retain only the necessary personal data required for legitimate purposes. This helps mitigate privacy risks by limiting the exposure of personal information.

      4. Consent and transparency: Individuals should be informed about the collection and use of their personal data linked to UPRNs. Organisations should obtain appropriate consent from individuals when processing their personal information and provide clear and transparent privacy notices that explain how the data will be used, who will have access to it, and the individual's rights regarding their data.

      5. Data sharing and third-party access: When sharing UPRN-related data with third parties, organisations must ensure they have appropriate data sharing agreements in place to safeguard the privacy and confidentiality of the data. They should also ensure that third parties comply with applicable data protection regulations and maintain adequate security measures.

      6. Anonymisation and pseudonymisation: Where possible, organisations may choose to anonymise or pseudonymise UPRN-related data to further protect individual privacy. This involves removing or replacing identifying information to ensure that individuals cannot be directly identified from the data.

It is essential for organisations to conduct thorough privacy impact assessments and adopt privacy-by-design principles when using UPRNs to ensure compliance with data protection requirements and protect individuals' privacy rights.

Implications of UPRNs in the Context of GDPR

UPRNs can be used to identify properties without directly including personal data, making them valuable tools for maintaining privacy in data handling. Here's how UPRNs can contribute to privacy:

      1. Separation of personal and property data: By using UPRNs, property-related information can be detached from personal data, such as names or contact details. UPRNs serve as unique identifiers solely associated with properties, allowing for the management and analysis of property-related data without the need to expose personal information.

      2. Data anonymisation: When sharing or analysing property-related data, UPRNs can be used as part of a broader anonymisation process. Personal identifiers are removed or replaced with UPRNs, reducing the risk of identifying individuals based on property-related information alone. This helps protect the privacy of individuals while still enabling effective data analysis and research.

      3. Aggregate data analysis: UPRNs allow for the aggregation and analysis of property-related data at a broader level, without focusing on specific individuals. This helps generate insights and understand trends without compromising individual privacy. For example, UPRNs can be used to analyse energy consumption patterns across properties or assess transportation needs in a particular area.

      4. Consent-based data handling: When collecting property-related data, organisations can seek consent from individuals based on the purpose of data collection. By clearly explaining how UPRNs will be used and ensuring that personal information is not tied directly to UPRNs, individuals can make informed decisions regarding data sharing while maintaining their privacy preferences.

      5. Secure data management: UPRNs can be utilised within robust data management systems that incorporate privacy-enhancing measures. Organisations can implement strict access controls, encryption, and other security measures to safeguard UPRN-related data, ensuring that only authorised personnel can access and process the information.

By leveraging UPRNs to identify properties without directly involving personal data, privacy risks can be minimised, and data handling practices can align with data protection regulations. It enables organisations to derive insights and conduct analysis while respecting individual privacy rights and maintaining the confidentiality of personal information.
