Moving Cities in France: The Admin Checklist Nobody Gives You

Moving flats is stressful enough. Moving cities in France means notifying half a dozen institutions separately, each with its own timeline and consequences for forgetting. This guide lays out exactly who you need to tell, in what order, and what happens if you don't.

2026 Regulatory Alert: Article 128 of loi de finances 2026 (loi n° 2026-103 du 19 février 2026) raised most titre de séjour fees from 1 May 2026: first issuance €200 → €300, multi-year residence cards (pluriannuelles) €225 → €350, reduced rate for students and family reunification €50 → €100, and standard renewal €300. If your address change triggers a new card issuance, verify current fees on the ANEF portal before proceeding.

In India, changing cities is mostly informal. You update your Aadhaar when you feel like it, tell your bank eventually, and life continues. France is the opposite. Every institution maintains its own database, none of them talk to each other automatically, and forgetting one can cause your benefits to stop or your residence status to become technically non-compliant. The good news: most of these are quick online declarations once you know what to do.

Your Titre de Séjour: The 3-Month Deadline

If you hold a titre de séjour (residence permit), you are legally required to declare your new address within three months of moving. You do this through the ANEF portal under "Déclarer un changement de situation."

A new physical card is not always required. If your permit is multi-year and still valid, many préfectures will simply note the change digitally. However, if a new card is issued, you'll pay the applicable tax stamp fee. Keep a copy of the confirmation email from ANEF as proof that you declared on time.

Warning: Failing to declare within three months does not automatically invalidate your permit, but it creates complications at your next renewal. The préfecture may question why the address on file doesn't match your current proof of residence. Don't give them reasons to delay.

CAF: Declare Immediately or Lose Your Benefits

Your CAF (housing benefit) allocation is tied directly to your address. The moment you move, your current APL or ALS stops being valid for the old address and you need a new calculation for the new one.

Log into your caf.fr account and declare the move under "Mon Compte" then "Déclarer un changement." You'll enter your new address, your new rent amount, and your new landlord's details. CAF will recalculate your benefit. Expect a gap of one to two months before the first payment at the new address arrives.

If you're moving to a different département, your file transfers to the new local CAF office. This happens automatically once you declare, but processing takes a few weeks. During this window, don't panic if your online account looks empty.

Ameli and Your CPAM: Same Département vs. Different Département

Updating your address with Ameli (health insurance) is quick if you stay within the same département. Log into ameli.fr, go to "Mes démarches," and update your postal address. Done.

If you're crossing into a new département, the process is slightly more involved. Your file transfers to the CPAM of your new département automatically after you declare the address change online. This transfer takes roughly two weeks. During that period, you're still covered, but you may need to update your Carte Vitale at a pharmacy terminal once the new CPAM confirms your affiliation.

One thing that catches people off guard: if you had a médecin traitant (declared GP) in your old city, you'll likely need to find and declare a new one in your new location. This isn't technically required by law, but seeing a doctor who isn't your déclaré GP reduces your reimbursement rate.

Your Bank: A Quick Update

Most French banks let you update your address through their online app or by visiting any branch. This is straightforward, but don't skip it. Your bank sends important correspondence (new cards, security alerts, tax documents) to your registered address.

If you're with an online bank like Boursorama, Fortuneo, or N26, it's a two-minute change in your profile settings. Traditional banks (BNP, SG, Crédit Agricole) may ask you to visit the new local branch to formally transfer your account if you're moving far.

Electricity, Gas, and Water: Close the Old, Open the New

French utility contracts are tied to the address, not to you. You cannot simply "transfer" your EDF or Engie contract to a new flat.

What you actually do: contact your current provider to terminate your contract on your move-out date (give them your final meter reading), then open a new contract at the new address. You can keep the same provider or switch. The new occupant at your old address will open their own contract.

Water is typically managed by the commune and often handled by the landlord or building syndic. Check your lease to see whether you need to act on this directly.

Internet: Transfer or Cancel and Restart

Your internet provider (Free, Orange, SFR, Bouygues) will offer you a "déménagement" (move) option. Whether this is genuinely faster than cancelling and opening fresh depends on the provider and the distance of your move.

The transfer usually takes two to three weeks, during which you may have no internet. If your new address already has fibre installed by a different operator, it can be faster to cancel your current contract (watch out for early termination fees if you're within your engagement period) and subscribe with the new operator directly.

Tip: Check fibre eligibility at your new address before deciding. Sites like ariase.com let you test by address. If your current provider doesn't serve fibre at the new location, you'll need to switch anyway.

La Poste: Mail Forwarding (Réexpédition)

France still runs on physical post. Your prefecture, your bank, your employer, and various administrations send letters to your registered address. Missing an important letter because you moved without forwarding is a real risk.

La Poste offers a paid mail forwarding service called réexpédition définitive (permanent forwarding). You set it up online at laposte.fr/demenager and all mail addressed to you at the old address gets redirected to your new one for the duration you choose.

The service starts from around 55 euros for six months domestically (verify current rates at laposte.fr/demenager). It's not cheap, but losing an official letter from your préfecture or a tax demand from the fisc is far more expensive.

Your Employer and Payslips

If you're employed, inform your HR department or employer of your new address. Your payslips (bulletins de salaire) must reflect your current address, and your employer needs this for your annual tax declaration filing. Most companies handle this with a simple email to HR or a change in their internal portal.

The Often-Forgotten Ones

A few things people forget in the chaos of moving:

• Phone plan: Your mobile contract (forfait) doesn't change with your address, but update it anyway so replacement SIMs get sent to the right place.
• Professional liability or home insurance (assurance habitation): Your assurance habitation at the old address needs to be cancelled or transferred. You legally must have home insurance at the new address before your first night there.
• Electoral registration: If you're registered to vote in France (EU nationals can vote in local elections), you'll need to re-register at the new mairie by the deadline before the next election.

The Indian Angle: Why This Feels Absurd

Coming from India, where you can change cities without notifying most institutions for months (or years) with minimal consequence, the French system feels obsessively bureaucratic. Every institution here operates in its own silo. CAF doesn't talk to Ameli. Your bank doesn't know you've moved until you tell them. The prefecture certainly won't check with La Poste.

The silver lining: almost everything is online now. You can realistically notify all of these institutions in a single afternoon from your laptop. Treat it as a one-time admin session on your first day at the new address, get it done in order, and you won't face any surprises later.
