AHV number and commune registration in Switzerland – what to do in your first 14 days
Last updated 25 September 2026Rules checked every MondayOfficial sourcesSources & methodology →
Registering with your commune makes your move official, and it brings your AHV number – the 13-digit Swiss social security number you keep for life. Here is who must register, where and with which documents, and how to find and use your AHV number.

Two things turn a newcomer into a resident of Switzerland: an entry in your commune's residents' register and an AHV number (Swiss social security number). The first you arrange within 14 days; the second usually arrives on its own. Both still happen the traditional way: voters approved the Swiss e-ID on 28 September 2025, but its launch was postponed on 30 June 2026 with no new date.
Who must register with the commune, and by when?
Everyone who moves, Swiss or foreign. The Register Harmonisation Act obliges the cantons to require registration within 14 days of a move. The Foreign Nationals and Integration Act adds that anyone who needs an L, B or C permit must register before the permit-free stay ends or before starting work.
| Your situation | Must you register? | Deadline |
|---|---|---|
| EU/EFTA citizen working more than three months | Yes | Within 14 days of arrival and before starting work |
| Non-EU worker with an entry authorisation | Yes – no work before registering | Within 14 days of entry |
| Not working, staying more than three months | Yes | Within 14 days of entry |
| Up to three months within six months, not working | No | – |
| Weekly resident, more than three months a year | Yes, at your weekly place of residence | Within 14 days |
| Swiss citizen returning from abroad | Yes | Within 14 days; the canton sets the deadline |

Registration is your job even where others report you too. In the City of Lausanne, landlords must report tenants moving in and out, but that does not replace your own registration, and federal law lets the register ask employers and landlords for information when someone fails to register.
Where do you register? Residents' offices in five cities
The office is usually called the Einwohnerkontrolle / contrôle des habitants (residents' office), though names vary, and each canton and commune sets its own procedure.
| Commune or canton | Office | How it works |
|---|---|---|
| City of Zurich | Personenmeldeamt Zürich Süd | In person, by appointment only; all family members attend; only from your actual move-in date |
| Basel-Stadt | Einwohneramt, Spiegelgasse 6 | Within 14 days (the online booking date counts); CHF 25 per person; fingerprints and photo for arrivals from abroad |
| City of Bern | Einwohnerdienste, Migration und Fremdenpolizei, Predigergasse 5 | Non-EU arrivals send the form, entry authorisation, passport and lease within 14 days; +41 31 321 53 00 |
| Canton of Geneva | OCPM (cantonal population and migration office), route de Chancy 88, Onex | 14 days on the French page, three months for EU citizens on the English page – register within 14 days and check; appointments only |
| City of Lausanne | Service du contrôle des habitants, Rue du Port-Franc 18 | Within 14 days; arrivals from abroad or another canton come in person, by appointment |

Later moves within Switzerland can often be registered online through eMovingCH (eUmzugCH) in participating communes if you are 18 or over – but not when you arrive from abroad, as the City of Bern points out.
What documents do you need to register?
Checklists differ by commune, but the City of Zurich's list for arrivals from abroad is typical.
| Document | Note |
|---|---|
| Passport | For EU/EFTA citizens an identity card is enough (City of Zurich) |
| Rental or sublet contract | Proof of your address |
| Permit assurance and visa authorisation | If you have them – mainly non-EU citizens |
| Employment contract or proof of studies | Shows the purpose of your stay |
| Original civil-status documents | Marriage certificate, children's birth certificates |
| Health insurance card or proof of cover | On the federal portal's list for in-person registration |
| Passport photo | Required by the City of Lausanne |
| Migration Office fees | On the City of Zurich list; billed separately in Basel-Stadt |

Basel-Stadt wants documents in German but accepts civil-status certificates in French, Italian or English or as international CIEC certificates; other languages need a certified translation. Newcomers there who are entitled to a B permit receive, at the Einwohneramt's welcome interview, a voucher for a free 80-lesson German course worth CHF 1,300.
After registration: permit card, fees and moving again
Non-EU citizens receive a biometric permit card with a chip holding two fingerprints and a facial image, captured by the canton. EU/EFTA citizens get a card without a chip, yet in the Canton of Zurich they still need a Migration Office biometrics appointment for photo and signature, booked via the commune. In the Canton of Geneva, biometrics appointments took two to four weeks in figures published on 21 September 2026.
Federal rules cap cantonal fees at CHF 95 for granting a permit, CHF 75 for an extension, CHF 22 for a biometric card and CHF 20 for capturing biometric data – and at CHF 65 in total for EU/EFTA citizens.
| Event | What you do | Deadline or cap |
|---|---|---|
| Move to another commune | Register at the new one, deregister at the old one | Within 14 days |
| Non-EU L or B holder moving canton | Apply for a permit from the new canton | Before moving; EU/EFTA permits stay valid |
| Move abroad | Deregister | At the latest 14 days before leaving |
| Permit about to expire | Apply for renewal | Between three months and two weeks before expiry |
| Permit lost or stolen | Report to the police, then request a duplicate | Fee capped at CHF 40 |
| Address change without a new card | Recorded by the canton | Fee capped at CHF 30 |

Leave without deregistering and your permit lapses anyway: an L permit after three months, a B or C permit after six.
What is the AHV number and how do you get it?
The AHV/AVS number, named after the old-age and survivors' insurance, is your 13-digit Swiss social security number. It starts with 756, is randomly generated and anonymous, is allocated once and stays the same for life, even if you marry. For foreign nationals the migration services normally create it when you settle. If you work and have none, your employer's compensation office requests it; universities request one for foreign students. Residents' registers must record it.
It has been printed on Swiss health insurance cards since 1 February 2010. The physical AHV card has not been compulsory since 2016 and is no longer issued automatically; you can still order one, and a replacement keeps the same number. Not knowing your number should not hold up health insurance registration or family allowances – opening an electronic patient record is the exception. Some services behind AGOV, the government login, require one.
| You are | Ask for your AHV number at |
|---|---|
| Employed | Your employer |
| Self-employed | Your AHV compensation office |
| Living in Switzerland, not working | Your commune of residence |
| A student | Your educational institution |

Contributions come out of every salary. Employees pay AHV/IV/EO contributions – old-age, disability and income-compensation insurance – of 10.6 per cent of salary, split equally: 5.3 per cent deducted from your pay, 5.3 per cent paid by your employer, with no upper income limit. People not in work pay from 1 January after their 20th birthday, at least CHF 530 a year in 2026. Each missing year cuts your pension by about 2.3 per cent, and gaps can be filled only within five years. Part 9 covers pensions.
What to do now
| Step | What | When |
|---|---|---|
| 1 | Book your residents' office appointment – Zurich, Lausanne and Geneva work by appointment | As soon as you know your move-in date |
| 2 | Gather originals: passport, lease, contract, civil-status documents | Before the appointment |
| 3 | Register every family member | Within 14 days of arrival, before starting work |
| 4 | Attend the biometrics appointment if invited | When the canton schedules it |
| 5 | Find your AHV number on your health insurance card, or ask your employer | In your first month |
| 6 | Report every later move to both communes | Within 14 days |
