Can a company choose its legal headquarters in Milan and operate in another city? The answer, in general, is yes. The legal headquarters identifies the official address of the business; offices, stores, laboratories, warehouses, and other places of activity can be located elsewhere. However, the configuration must accurately represent the actual organization of the company.
The doubt becomes concrete when a business works remotely, opens a retail outlet outside Milan, maintains a warehouse close to customers, or transfers the legal headquarters but continues to operate in the old office. In these cases, it is not enough to mentally separate the "formal" address from the "operational" one: it is necessary to understand if the second location constitutes a local unit, what data must appear in the Business Register, and who oversees the communications received at the legal headquarters.
This guide, verified on August 10, 2026, explains how to set up the preliminary check. The indications are general: legal form, activities carried out, authorizations, personnel, contract related to the premises, and actual distribution of functions may require a specific professional assessment.
Legal headquarters, operational headquarters, and local unit: the useful difference
The legal headquarters is the official address of the company, resulting from the deeds and the Business Register. The Business Register portal describes it, as a rule, as the place where the administrative center of business is indicated in the articles of incorporation. Every business has a legal headquarters, while it can organize its activities in multiple locations.
The operational headquarters is one of the places where the activity is carried out concretely. It can coincide with the legal headquarters or be separate. "Operational headquarters" therefore describes the practical function of a place, but it should not be used as an informal label to avoid verifying how that location should be communicated.
The Business Register defines local units as operational or administrative and managerial facilities located in places different from the legal headquarters, where the business permanently carries out one or more specific activities. Examples include offices, stores, laboratories, workshops, plants, warehouses, depots, branches, and agencies.
The distinction serves to read the business as a map: an official legal headquarters, any stable places of activity, and, for each place, a verifiable function. It does not depend on the commercial name given to the space, but on how it is actually used.
Can you have the legal headquarters in Milan and operate in another city?
A company can have its legal headquarters in Milan and one or more local units in other municipalities or provinces. This model is common in businesses that separate administration, production, logistics, sales, and team work. The presence of activity elsewhere does not in itself make the Milanese legal headquarters inconsistent; however, it requires that the different locations be qualified and registered correctly.
Let’s think of a service company with its legal headquarters based in Milan and a stable office in Bologna, or a commercial enterprise with an official address in Milan and a warehouse in the province of Bergamo. In both cases, the relevant question is not just where people work, but what activities are carried out consistently in the second location, with what means, under what title of availability, and with what possible administrative requirements.
The old address also deserves attention when the company transfers its legal headquarters. If the activity continues consistently in those premises, it should not be taken for granted that the location disappears from the company’s structure: it may be necessary to frame it as a local unit. If, on the other hand, the location is abandoned, corporate data, contracts, correspondence, and communications must follow the new configuration.
Separating legal headquarters and operations can offer flexibility, but it must not create an official address isolated from business processes. The legal headquarters must remain reachable and staffed, while the operational locations must be represented in a way that is consistent with the actual activity.
When an operational location can be a local unit
Not every place occasionally frequented by the entrepreneur automatically becomes a local unit. The central criterion indicated by corporate sources is the stable conduct of an operational, administrative, or managerial activity in a location different from the legal headquarters.
A store open to the public, a laboratory, a continuously used warehouse, or an office organized for a business function are recognizable examples. An occasional meeting at a client’s location, a meeting room booked for a day, or a workstation used sporadically require a different interpretation. Frequency alone does not resolve every case: function, continuity, organization, and the activity actually carried out matter.
Before classifying the location, it is advisable to gather at least this information:
- complete address and title that allows its use;
- activities performed and actual start date;
- presence of personnel, equipment, goods, or public access;
- stable or occasional nature of the use;
- authorizations, communications, or requirements related to the activity and the territory;
- relationship with the legal headquarters and with other locations already present in the registration.
A secondary office is a further concept. The Business Register distinguishes it from the local unit by the presence of a stable representation and its corporate framework, referring to Article 2197 of the Civil Code. Therefore, calling any office a “branch” is not enough to determine its legal nature: classification must be verified on a case-by-case basis.
What to communicate and how to check the registration
The opening or variation of a location falls under the obligations towards the Business Register. The official portal indicates the Single Communication as the online method for variation practices and specifies that the operational headquarters must be regularly communicated to the competent Chamber of Commerce. The composition of the practice depends on the type of business, the location, and the entities involved.
When the local unit is located in a province different from that of the legal headquarters, territorial competence and the forms must be checked with particular attention. The SUAP of the Municipality, any communications of activity start, social security or insurance positions, and specific sector requirements may also be relevant. There is no identical administrative checklist for a consulting office, a warehouse, a laboratory, and a retail outlet.
After the practice, it is useful to read an updated chamber registration. The document allows you to verify the address of the legal headquarters, secondary locations, and local units, in addition to the activities declared for the different locations. The check should not be limited to the existence of the address: name, activity, status of the location, and organizational data must be consistent with what actually happens.
The same verification should be extended to the documents used every day. Website, email signatures, contracts, invoices, general conditions, letterhead, and business profiles should not lead to the belief that the legal headquarters is a store, a showroom, or an office open to the public when it is not. Similarly, a stable operational headquarters should not remain invisible in the administrative processes concerning it.
What does legal domiciliation cover and what remains separate
Legal domiciliation allows, when the contract and the corporate situation permit, to use an address as the registered office and to organize the receipt of related correspondence. It does not automatically grant the right to carry out operational activities on the premises, receive clients, store goods, or install personnel and equipment.
For this reason, the contract must be read together with the operational model of the business. If only a monitored official address is needed, domiciliation can meet that need. If workstations, meeting rooms, storage, continuous access, or uses subject to authorization are also required, these elements must be expressly stated and verified separately.
Mail also requires an internal process. It is necessary to define who receives the notice, how the document is forwarded, who checks for any deadlines, and what happens during absences or changes of contact person. The presence of certified email and digital domicile does not make physical correspondence irrelevant: both channels must be monitored in a coordinated manner.
Domiciliation, finally, does not replace an accountant, notary, labor consultant, or professional responsible for the practices. Its scope concerns the registered office and the services provided by the contract; the qualification of locations and related obligations depend on the actual structure of the business.
A checklist for designing a business with multiple locations
Before choosing the registered office in Milan, draw a simple map of all the places used by the business. For each one, indicate function, frequency, people present, activities carried out, goods stored, public access, and any necessary authorizations. This step immediately highlights addresses that are not just occasional contact points.
Then share the map with the professionals who follow companies and obligations. The verification should clarify at least:
- which address will be the legal headquarters and how it will be monitored;
- which locations constitute local units or require a different classification;
- which practices must be submitted and to which competent office;
- which activities must be reported for each location;
- who will update the registration, contracts, website, and company documents;
- who will manage physical mail, certified email, and received communications;
- how future openings, closures, or changes will be monitored.

FAQ
Can a company have its legal headquarters in Milan and its local unit in another region? In general yes. However, it is necessary to correctly communicate the location and verify the applicable territorial and sectoral obligations related to the activity carried out.
Is the operational headquarters always a local unit? It is not prudent to respond solely based on the name used by the company. It must be verified whether a stable operational, administrative, or managerial activity is carried out at a location different from the legal headquarters and how the location must be registered with the Business Register.
Can I work remotely if the legal headquarters is located in Milan? Separation is possible, but remote work, the potential stable presence of personnel, and the use of other premises must be evaluated in relation to the actual organization and applicable obligations.
Should a warehouse in another province be indicated? A warehouse used on a stable basis falls among the examples of local units indicated by the Business Register. The practice, declared activities, and any requirements must be verified with the appointed professional.
Does legal domiciliation allow receiving clients at the headquarters? Not automatically. The use of the address as a legal headquarters, the management of mail, and access to spaces or rooms are different rights that must be specified in the contract and be compatible with the use of the premises.
How do I verify if the legal headquarters and local units are registered correctly? Request an updated chamber registration and compare it with the addresses, activities, and actual status of each location. If discrepancies arise, have them evaluated before submitting a change.
Is the secondary headquarters synonymous with a local unit? No. The secondary office implies a stable representation and has a specific framework; not every local unit is a secondary office.
