Text message from your town hall or a public service: real or fake?

Short answer: a town hall, a prefecture or a French government body can legitimately send you a text message — a municipal safety alert, a reminder about a counter appointment, information about a polling station, news that an official document is ready. These messages arrive from a short code or an alphanumeric sender ID (such as "MAIRIE" or "ANTS"), are free to receive and never ask you to pay, enter a bank card number or "confirm" a tax reference via a link. Any "official" text message demanding a payment or login details should be forwarded to 33700.

Updated 27 October 2026.

The village of 3,000 people warning of a water outage, the driving test centre confirming a slot, the prefecture announcing that a document is ready for collection: the text message has become an ordinary administrative channel. It's short, it arrives, and it doesn't require opening an email inbox.

This normalisation comes at a price. Now that people in France are used to receiving messages from public services, scammers have realised that a text signed "Service Public" or "Mairie" opens doors that a message from an unknown brand never would. Administrative authority is the most effective appeal to authority there is.

Can a town hall really send me a text message?

Yes, and it's increasingly common. Municipalities use SMS alert platforms to warn residents about local events: bad weather, water or power cuts, school closures, roadworks, pollution, civil defence drills, missing-person appeals.

These systems rely on voluntary sign-up: you left your number at the counter, on the municipal website, when enrolling a child at school, or by filling in an "alert system" form. If you don't remember doing so, it's often because the box was ticked inside a broader application — school canteen registration, library membership, holiday activity club.

Two useful markers:

• a municipality has no financial interest in writing to you: its message informs, it sells nothing and charges nothing;
• it writes about your area and within your timeframe (a water outage announced for tomorrow morning in your street, not a vague "national case file").

Alongside town halls, since 2022 the French state has had the FR-Alert system, which broadcasts civil defence alerts to phones located within a given geographical area. It isn't a standard text message: it appears full screen, with a piercing alarm tone even in silent mode, and it never contains a link to click. The Ministry of the Interior explains how it works on the official FR-Alert page. So a "government alert message" received like an ordinary text, complete with a URL, is not FR-Alert.

Which public services actually send text messages?

The most frequent senders, and what their messages contain:

Sender	What the message announces	Does it ask for payment?
Town hall / inter-municipal authority	Local alert, roadworks, facility closure, registration reminder	No
Prefecture / ANTS	Document (ID card, passport, driving licence) available, case progress	No
Social security funds (CAF, Assurance Maladie, CPAM)	Appointment reminder, missing document, campaign information	No
Direction générale des Finances publiques	Deadline reminder or notice that a document is online	No
Examination centre, approved driving school, health centre	Slot confirmation or reminder	No
France Travail	Interview reminder, monthly status update	No

The rule is brutally simple: no French public service will ever ask you by text message to pay online, or to enter a bank card number, a social security number or a password. Government bodies work through their authenticated personal accounts — impots.gouv.fr, ameli.fr, ants.gouv.fr, caf.fr, France Connect — never through a link received in a message.

The Direction de l'information légale et administrative restates this principle on service-public.fr, and cybermalveillance.gouv.fr publishes quick-reference sheets on phishing that apply word for word to text messages.

What do fake official text messages look like in 2026?

They always latch onto a moment in administrative life where a request for money or paperwork seems plausible. The most commonly seen families of messages:

1. "Your ID card / driving licence is ready, pay €1.95 in delivery fees" — ANTS has no delivery fees payable by text message; documents are collected at the town hall or sent without any such surcharge.
2. "You are not registered on your municipality's electoral roll, please put this right before…" — registration can be checked free of charge on the official state service, never via a link you've received.
3. "Your census / council tax file is incomplete" — no tax service asks for documents via an SMS link.
4. "Increased fine" or "unpaid parking charge" — a variant already very well documented among drivers.
5. "Your benefit application has been approved, confirm your IBAN" — a request for bank details is the clearest possible sign of an attempted scam.

A fake message almost always gives itself away on three points:

• the sender: an 06/07 mobile number, a foreign number, or a sloppy alphanumeric sender ID ("Gouv-Fr", "ServicePublic24");
• the link: a domain that isn't .gouv.fr, often padded out (impots-regularisation-fr.com, ants-titre-securise.net);
• the deadline: 24 hours, 48 hours, "before tonight" — urgency is the fuel of every scam.

How can I check an official text message in two minutes?

Verification never goes through the message itself. It goes through a channel you choose.

1. Don't touch the link. Not even "just to look". A well-built phishing page can be an exact copy of the official site.
2. Identify the service concerned from the content: identity document → ANTS; benefits → CAF; tax → DGFiP; civil registration, school canteen, local alert → town hall.
3. Open the site or app yourself by typing the address, or from a saved bookmark. If something genuinely requires action, it will show up in your personal account.
4. Call your town hall's reception desk using the number listed on its official website (not the one in the text). This is the most effective reflex for messages with a local angle.
5. Cross-check with your post. A government body expecting an important document almost always backs up its message with a paper letter or a message in your personal account.

For residents juggling plenty of paperwork, keeping supporting documents in one place is a game changer: an expanding file folder for administrative papers saves you hunting for a tax notice or a filing receipt at the exact moment a text message claims something is missing. Verification becomes instant.

When the town hall writes to the whole municipality

Local alerts have a recognisable signature: they are impersonal (no "Dear Mrs X"), geographically precise and involve no online action. "Water outage on rue des Lilas and rue Pasteur, Tuesday 8am to 12pm" needs no link. Conversely, a message claiming to come from the town hall and inviting you to "update your administrative file" on a third-party site makes no sense: your municipality already holds your file.

Can I unsubscribe from my municipality's text messages?

Yes, and it's a right, not a favour. A local authority's messages rely on personal data processing governed by the GDPR and the French Data Protection Act. You can ask for your number to be removed from the alert system or the information list by writing to the authority's data protection officer (DPO) — their contact details appear in the legal notices on the municipal website.

In practice:

• most municipal alert platforms accept STOP as a reply text or offer a preference management area;
• the CNIL sets out the applicable rights (access, objection, erasure) and the complaints procedure on cnil.fr;
• a word of warning: unsubscribing from a municipal civil defence alert also cuts you off from the useful messages. FR-Alert, on the other hand, requires no sign-up and cannot be "unsubscribed" from: it is purely geographical.

One detail that matters for alert messages: if you want to be woken by a night-time alert without leaving your phone on the bedside table, an inductive charging stand placed somewhere visible in the bedroom keeps notifications in sight without taking the phone out of night mode.

For how the word "STOP" works and its real limits depending on the type of sender, we've broken down the mechanism in Replying STOP to a text message: does it actually work?.

What should I do if I clicked on a fake public service text?

The order of the steps matters more than speed.

1. If you entered nothing: close the page and don't go back to it. Simply viewing a phishing page steals nothing.
2. If you entered bank card details: call your bank's emergency number immediately, block the card, then dispute the unauthorised transactions.
3. If you entered login details (FranceConnect, impots.gouv.fr, ameli, CAF): change the password from the official site, and enable two-factor authentication wherever it's offered.
4. Keep the evidence: a screenshot of the message with the sender number visible, the timestamp, the link address.
5. Report it: forward the message to 33700 (free, all networks), file a report on the Phishing Initiative platform or via cybermalveillance.gouv.fr, and file a police complaint if you suffered financial loss.
6. Monitor your accounts for several weeks: stolen credentials are sometimes used months later.

On the digital hygiene front, two objects help more than you'd think: a FIDO2 security key to lock down your most sensitive accounts, and a simple password notebook kept out of sight for those who refuse software managers. Nothing is compulsory, but anything beats the same password everywhere.

How can I cut down on these messages in future?

• Turn on the spam filter in your messaging app. Google Messages and the iOS Messages app can both quarantine unknown senders; the setting is in the app's preferences. Our guide to iOS and Android settings spells out the exact paths.
• Only give your number where it's genuinely needed. Municipal forms rarely require it for compelling reasons.
• Read the consent boxes in registration forms (school canteen, library, holiday club): they often determine what gets sent to you later.
• Sign up to Bloctel for cold calling, bearing in mind that it doesn't cover SMS fraud, which by nature ignores any opt-out list.
• Always report to 33700: it's the channel that allows operators to shut down the sending numbers.

For people who get hit particularly hard, a basic secondary phone dedicated to paperwork and online forms remains the most radical way of compartmentalising. We covered it in detail in our article on having a second number.

FAQ

Can a town hall send me a text message without my consent? For information or advertising, no: it needs a legal basis and, in practice, your sign-up. For a civil defence alert broadcast via FR-Alert, yes — the system is geographical and requires no prior registration.

Do ANTS or prefecture text messages cost money? No. Receiving them is free, and no identity document is ever "released" in exchange for a payment of a few euros by text. A message demanding "delivery fees" is fraudulent.

How do I recognise a genuine French government link? Official state websites use a .gouv.fr domain (impots.gouv.fr, ants.gouv.fr, service-public.fr), while municipalities use their own domain, which is listed in their official documents. Anything with extra words added before or after (ants-titres.com) is suspect.

I've forwarded the text to 33700 — what happens now? You receive a request to send in the sender's number, then your report feeds the operators' shared platform, which can block the source. You won't get individual feedback on the outcome.

The text came from an 06 mobile number: does that automatically mean it's a scam? Not necessarily — a council employee or an office secretary may write from a work mobile. But in that case the message contains neither a link nor a payment request. A "public service" writing from an 06 number with a link combines two warning signs.
