What to do if you lose your French carte de séjour

If you're a foreigner living in France, you may need a carte de séjour to prove your right of residency - but what happens if this precious document is lost or stolen?

If you’re a non-EU citizen and you’re living in France you will almost certainly need to get a carte de séjour residency permit, and keep it up to date to prove your right of residency.

If your card is lost, or you fall victim to pickpockets, you will need to replace it, but this can be a complicated process.


In theory, the process of demanding a duplicata or replacement of your carte de séjour is quite simple and can be done online, via this page. It doesn’t always work, however (see below).

There is €225 fee, or €75 fee if you are a student or applied for your card as part of a family.

You will need to submit the following documents electronically: 

  • A self-written document, declaring that you have lost the carte de séjour (you can find an example here – but obviously, remove the letterhead;
  • A copy of your original carte de séjour (if you have one – it’s recommended that everyone photograph the front and back of their card when they get it, just in case);
  • A copy of your passport (including pages with ID information and and entry stamps);
  • A copy of your birth certificate (the French are obsessed with birth certificates); 
  • If your right of residency comes through marriage or family, a copy of your partner/family member’s carte de séjour or ID card, as well as your marriage certificate; 
  • Proof of address;
  • Three ID photos; 
  • Proof of payment of the fee. 

If you have the necessary documentation, this process should take a matter of weeks. 

If you lose your carte de séjour overseas 

Things become a little more difficult if you lose your carte de séjour overseas. 

You must first declare the loss to local police authorities and then to your closest French embassy or consulate (who will want to see proof that you have declared your loss to the police as well as a déclaration sur l’honneur).

Be sure to have official written evidence of both declarations, signed or stamped by the authorities – you may be asked to provide it as evidence when asking for a replacement. 

In order to return on France, you may need to ask for a visa de retour from the embassy or consulate concerned. Before giving you this visa, they will need to verify that you once obtained a carte de séjour from whichever préfecture you applied to. A harrowing advisory is written on “This investigation can be lengthy.”

Upon your return to France, you must apply for a duplicata via this website

You will need all the same documents as if you had lost your carte de séjour in France. 


The online process is fairly new and it seems that it doesn’t work for everyone, with several Local readers who got the post-Brexit carte de séjour for UK nationals reporting that their card number is not recognised. 

In order to create the online account necessary to demand a duplicata, you must enter your visa or titre de séjour number (also known as a numéro AGDREF). This is a 13-digit number which on a standard carte de séjour is either along the top or the side, as below.

On the post-Brexit carte de séjour it is listed as the Numéro personnel and is just above the signature on the card.

Unfortunately, the online portal often bugs and displays a message indicating that your number is not recognised. 

If this happens, you need to book an appointment at the préfecture which issued your card in the first place. If the system doesn’t recognise your card number then it may not be possible to use the préfecture’s online booking system.

Préfecture appointment

If you’re unable to use the online booking system you will have to either email, call or show up at the préfecture and explain the situation in as much detail as possible. It may be worth taking screenshots showing that the online system rejected your card number.

Different préfectures have different systems but in Paris, where carte de séjour applications are dealt with by the Préfecture du Police, the online form to send such a mail, can be found here or email [email protected] 

Préfectures will then send you either an appointment, or a letter inviting you to visit when convenient. Some have their own list of required documents which can be different to the ones demanded by the online portal, so take careful note of what they are asking you for.

In Paris, the préfecture ask for:

  • A valid passport;
  • ID photos;
  • A declaration of the loss of my carte de séjour, obtained from the police (in Paris, you must go to the commissariat de 13eme);
  • Proof of address; 
  • A copy of the lost carte de séjour (if possible). 

Most préfectures will process your request and then send out the card in the post within four weeks. 

Under the Withdrawal Agreement, the post-Brexit carte de séjour was free, and it seems that UK nationals who have lost their cards are not being asked to pay a fee for a replacement, although this may vary.
