LAU (Local Administrative Units)

Local Administrative Units, commonly abbreviated as LAU, represent the municipal layer of Eurostat's geographic classification system. They sit below NUTS Level 3 in the territorial hierarchy and cover individual communes, municipalities, parishes, and equivalent local administrative entities across EU member states. While LAU codes are not formally part of the NUTS classification, they are maintained by Eurostat in correspondence tables that link every LAU unit to its parent NUTS Level 3 region.

What are Local Administrative Units?

LAU are the basic building blocks of European local governance: a French commune, a German Gemeinde, a Polish gmina, a Spanish municipio, or a Swedish kommun. There are approximately 100,000 LAU units across the 27 EU member states, ranging from the city of Paris (a single LAU with over 2 million inhabitants) to tiny Alpine communes with populations of a few hundred.

Each LAU unit has a unique numeric code within its member state, and Eurostat publishes annual correspondence tables mapping every LAU code to its parent NUTS Level 3 code. This mapping allows statistical data collected at the municipal level to be aggregated upward through the NUTS hierarchy for Eurostat reporting.

LAU codes were formerly known as NUTS Level 4 and NUTS Level 5, but were separated from the formal NUTS hierarchy in 2003 when the NUTS Regulation confined the official classification to three sub-national levels. The current LAU framework replaced the older NUTS 4/5 system and is now maintained under a separate Eurostat administrative process.

Why LAU matters for bidders

LAU codes rarely appear directly in the standardised fields of an EU contract notice on TED. The place-of-performance field in the standard notice forms calls for a NUTS code, and contracting authorities satisfy that requirement at NUTS Level 3 or above. However, LAU data is relevant to bidders in several indirect ways.

For hyper-local market intelligence, LAU-level datasets (for example, municipal procurement budgets, local government annual accounts, or open spending data from national portals) can be combined with NUTS-level TED data to build a comprehensive picture of procurement activity in a specific area. A company targeting contracts from a group of municipalities in the Veneto region of Italy, for instance, can use LAU codes to identify and track those specific authorities in national procurement portals, even when their individual notices fall below EU thresholds and do not appear on TED.

For below-threshold contracts (those below the Directive 2014/24/EU value thresholds), national and regional procurement portals often use LAU-equivalent codes or municipal identifiers as the primary geographic field. Understanding the LAU layer helps bidders navigate these national systems in the same conceptual framework as the NUTS hierarchy they already know.

Example

A grounds maintenance company operating in the south of the Netherlands wants to monitor contracts from individual municipalities in the province of Zeeland. The relevant NUTS Level 3 code for Zeeland is NL341. The company uses Eurostat's LAU correspondence table to identify all municipalities (LAU units) that fall within NL341, then monitors the Dutch national procurement portal TenderNed for contracts from each of those specific municipalities, complementing the NUTS-filtered TED search it already runs for above-threshold contracts.

Frequently Asked Questions

Are LAU codes used in TED contract notices?

LAU codes are not a required field in the standard eForms notice templates used on TED under Implementing Regulation (EU) 2019/1780. The place-of-performance field requires a NUTS code. However, contracting authorities may optionally provide additional location details, including a town or municipality name, in supplementary free-text fields.

Do LAU boundaries change as frequently as NUTS boundaries?

LAU boundaries change more frequently than NUTS boundaries because municipal mergers, splits, and renaming happen continuously across member states as part of local government reorganisation. Eurostat publishes an updated LAU table annually, unlike the NUTS classification which is reviewed every three years.

Is there an equivalent of LAU for the UK after Brexit?

The UK uses Lower Layer Super Output Areas (LSOA) and Output Areas (OA) for statistical purposes below the ITL (International Territorial Level) hierarchy, which replaced NUTS post-Brexit. These do not directly correspond to LAU because the UK's local government structure differs from most EU member states. For procurement, UK local authorities are identified by their organisation codes in the Find a Tender service.
