Registering in Monaco – where you register, the residence certificate and your social security number

Last updated 25 September 2026Rules checked every MondayOfficial sourcesSources & methodology →

Living in Monaco means no town-hall registration and no personal ID number. Instead, the police residents' section keeps your file, a certificate proves where you live, and your employer's hiring request gives you the number the social funds run on. Here is how the three fit together.

Living in Monaco means learning one address early: 9 rue Suffren-Reymond, home of the Sûreté Publique – Section des Résidents (the police residents' section). Under Sovereign Ordinance 3.153 the police receive residence-card applications and issue the card; there is no municipal registration for foreigners. Two recent changes: since 18 December 2025 the administrative residence certificate can be ordered and paid for online on MonGuichet, and since 2025 the Caisses Sociales registration card has gone digital.

Living in Monaco without a personal ID number

Newcomers from Scandinavia or Spain look for the number that unlocks everything. Monaco does not have one: the Government's settling-in checklist contains no step for a personal identification or tax number. Two documents identify you instead – the residence card, which you must be able to show whenever the authorities ask, and, if you work, your matricule (registration number) with the Caisses Sociales de Monaco.

New cards carry an optional digital identity under Law 1.483 of 17 December 2019, activated at handover or at the self-service kiosk at the section; with a USB card reader and a five-digit PIN you log in to online services and sign documents, and it can be installed in the MConnect Mobile app.

The Section des Résidents: what it does and how to reach it

The section's reception unit handles residence files; its inquiry and control unit examines residence-certificate requests and checks that residence is effective, and can withdraw or reclassify a card. Opening hours are Monday to Friday 9:00 to 17:00 on most official pages, though the change-of-address page says 9:30. Two sets of phone numbers are in circulation: the MonServicePublic residence pages give (+377) 93 15 30 15, while the Prince's Government's online directory lists (+377) 93 15 30 17 and (+377) 93 15 30 60.

Which residence certificate do you need?

Three documents are called certificates, and they do different jobs. The certificat de résidence administratif (administrative residence certificate) is what schools and administrations usually want. It goes to holders of a valid residence card who, under Ordinance 8.566, certify on their honour that they live in Monaco more than six months a year or have the main centre of their activities there. People settled for less than six months get one only with an exception. It is valid six months and costs €5 – a tax stamp on paper, or paid online since 18 December 2025.

The certificat de résidence à des fins de formalités fiscales (residence certificate for tax purposes) is the heavy one, for a foreign bank or tax office. You need a valid card and one of three things: more than 183 days a year in Monaco, your main centre of activities there, or your longest stay of the year there; you also show the past year's water, electricity and telephone bills. It is valid one year and costs €600, paid on collection by appointment; the request goes by email or post with the requesting body's letter, your identity document, latest utility bill and proof of income.

French nationals are a case apart. Under Article 7 of the 1963 Franco-Monegasque tax convention they pay French income tax as if they lived in France, and the Direction des Services Fiscaux issues the certificat de domicile (certificate of domicile) only to the exceptions – habitual residence in Monaco since before 13 October 1957, or uninterrupted residence since birth. It costs €12 and is valid three years. Part 7 covers tax.

Your social security number: the matricule

You do not apply for a social security number; your employer does, and hiring and registration are one file. As soon as the demande d'autorisation d'embauchage (hiring-authorisation request) is lodged with the Service de l'Emploi, the file goes to the Caisses Sociales, which record you and issue a provisional registration certificate. The number identifies each employee working in Monaco and is the precondition for benefits from the CCSS (health and family), the CAR (basic pension) and the CMRC (supplementary pension). It requires a work permit: if the hiring is refused, the registration ceases to have effect.

Registration starts on your hiring date but cannot be backdated before the request was filed. If your employer files more than a month after you start, it can be made to repay the medical and family benefits paid to you meanwhile. The self-employed join the CAMTI and CARTI within one month of starting, through the Service du Recouvrement des Cotisations on (+377) 93 15 43 93.

When something changes

A foreigner who changes residence or activity, even within Monaco, must tell the Sûreté Publique within eight days, on pain of a fine. Every change of address, family situation, nationality or job goes to the Section des Résidents even while the card is valid, and a new card costs €30. For an address change bring the final energy bill from the old address, the new registered lease or title deed, the latest rent receipt and the new electricity or gas contract. One office takes the declaration and informs the public car parks, the vehicle registration office, the Caisses Sociales, the Mairie and the Journal de Monaco.

Leaving Monaco for good, you return your residence card – and those of family members leaving with you – eight days before departure, with proof of the date such as the SMEG termination invoice or the end-of-lease statement, and your new address. The Sûreté Publique issues a single attestation of your stay, useful for customs, banks and consulates – keep it safe.
