Registering a vehicle without a transfer code: what to do in 2026

You bought a used vehicle and the ANTS is blocking your file for lack of a transfer code? This scenario is common. This guide recalls what the code is for, why it may be missing, details seller / buyer timelines, and above all how to unlock registration depending on your situation — including when the declaration has already been filed by an accredited professional (often without a code).

Reminder: what is the transfer code for?

When a private individual declares a sale on the ANTS portal, a transfer code (code de cession) is generated. The seller must pass it on to the buyer (SMS, email, paper). On the ANTS, this code links the sale declaration to the change-of-ownership file: without that IT link, the private path cannot complete.

• The seller has 15 days to declare the sale after the transfer.
• The buyer has one month to apply for the registration certificate.
• The code has a limited validity (often described as around 15 days in ANTS practice): once that window has passed, the situation must be resumed with the seller or a professional.

For the full mechanism, also read The transfer code: what is it? and the vehicle transfer declaration procedure.

Seller / buyer timeline

Step	Who	Usual deadline	Comment
Signed transfer + crossed-out carte grise (date and time)	Seller + buyer	Day 0	Without the time, the file is often rejected
Sale declaration	Seller	15 days	ANTS or accredited provider
Hand over the code (if ANTS path)	Seller	As soon as issued	Note the code and issue date
Carte grise application	Buyer	1 month	ANTS or accredited provider
Practical code validity	Buyer	Short (~15 days)	Act quickly; otherwise resume

Ideally, seller and buyer agree before handing over the keys on the declaration channel (ANTS alone vs professional) to avoid blockages.

Why is the code missing?

• The seller has not declared the sale (oversight, ANTS difficulty, missing co-owner, blocked FranceConnect account).
• The code has expired and the buyer could not finish in time (incomplete documents, roadworthiness test to redo, holidays).
• The declaration was filed with an accredited professional: in that case there is generally no code to enter — the buyer’s file follows another path.
• Data entry error (identity, date, time, plate) or a dispute between the parties.
• Co-owner forgotten on the transfer: the ANTS declaration cannot complete until all signatures are gathered.

What happens on the ANTS without a code?

Without a code (and without an associated professional declaration), the “change of ownership” path on the ANTS cannot complete normally. The buyer remains exposed: driving with a carte grise not in their name, risk of fines, and the seller remains legally vulnerable as long as the sale is not recorded (fines, parking, etc. may still come back).

An accredited professional such as Office Carte Grise can often take over the file as soon as the sale documents are correct (Cerfa 15776, crossed-out carte grise, identities). That is precisely the value of the accredited circuit: it does not depend on the code generated for private individuals.

What an accredited professional does differently

Unlike the public ANTS path, an SIV-accredited provider:

• registers the sale without generating a buyer code to paste into a form;
• can chain sale declaration then change of ownership in the same workflow;
• checks consistency of Cerfa forms, the crossed-out carte grise and identity documents before transmission;
• generates or completes the mandate (Cerfa 13757) and the registration application (Cerfa 13750).

If the seller has already declared with an accredited provider, the buyer does not need to “find a code”: they prepare their change of ownership file with the sale evidence.

Practical solutions case by case

1. The seller has not yet declared

Follow up immediately, ideally in writing (dated SMS / email). The declaration can be made:

• on the ANTS (the seller then obtains the code to send you);
• via our vehicle transfer declaration procedure (Cerfa forms generated or uploaded) — often simpler if the seller is stuck on FranceConnect.

Seller-side documents: identity, any co-owner, original carte grise to cross out, Cerfa 15776 signed by both parties (and co-owners), sale date and time. Once the declaration is registered, ask for the code (private ANTS path) or continue directly with the professional if that is the chosen route.

2. Declaration already filed with a professional (often without a code)

If the seller (or the garage) registered the sale via an SIV-accredited provider, you generally have no code to enter. Prepare your change-of-ownership file with: signed transfer certificate, crossed-out carte grise, roadworthiness test where applicable, identity, address, licence, insurance, Cerfa 13750 / mandate 13757.

Tip: ask the seller or garage for the file / acknowledgement number of the professional declaration if available; it helps follow-up even without an ANTS code.

3. Expired or “already used” code

If the code expired before you could finish: contact the seller to resume the situation, or go through an accredited provider with the paper documents. If the message says “code already used”, a code can only be used once: a failed attempt after consumption may require ANTS support or an accredited provider with your evidence (screenshots, acknowledgements).

4. Seller unreachable or acting in bad faith

Keep all evidence (signed transfer, exchanges, payment, date/time, photos of the crossed-out carte grise). A formal notice may help. An accredited provider can say whether the file is technically processable with the documents you hold. In cases of proven fraud (forged transfer, undeclared lien, etc.), other routes (complaint, opposition) may be required — beyond a simple administrative oversight.

5. Purchase from a professional (purchase declaration)

If the seller is a motor trade professional, they must give you in particular the purchase declaration receipt together with the transfer certificate and the crossed-out carte grise. See the purchase declaration and, for professionals, our PRO procedure. Again, the “private transfer code” is usually not the right tool: the professional circuit is what counts.

Documents to prepare for the change of ownership

Document	Buyer	Seller	Notes
Identity (+ driving licence)	Yes	Yes (declaration)	Valid
Proof of address < 6 months	Yes	—	In the holder’s / household name
Insurance certificate	Yes	—	Vehicle covered
Carte grise crossed out with date/time	Yes (handed over)	Yes	“sold on / transferred on”
Cerfa 15776 (transfer)	Yes	Yes	All signatures
Roadworthiness test < 6 months	If applicable	—	Typically passenger cars > 4 years
Cerfa 13750 + mandate 13757	If accredited	—	Generator recommended

Download the forms via CERFA forms to print or prepare them with the document generator: entering identity, vehicle and addresses once reduces crossings-out and refusals for inconsistency between 15776, 13750 and 13757.

What NOT to do

• Do not drive indefinitely with the carte grise in the seller’s name while waiting for a code that “will turn up”.
• Do not invent a code or reuse one from another sale.
• Do not cross out the carte grise without date and time, or alter a time already declared without consistency.
• Do not forget the co-owner (or spouse in community of property where relevant) on the transfer.
• Do not confuse the private ANTS path with the professional path: hunting for a code when the sale is already with an accredited provider wastes days.
• Do not discard payment evidence and the signed transfer “because the garage is handling it”.

Typical scenario: a 10-day timeline

Day 1 — transfer signed, carte grise crossed out with date and time, keys and originals handed over. Day 2 — the seller declares with an accredited provider or on the ANTS; if they choose the ANTS, they send you the code the same day. Days 3–5 — you finalise insurance, roadworthiness test if needed, and Cerfa 13750 / 13757 via the document generator. Day 6 — file the change of ownership with an accredited provider (no code if professional declaration) or on the ANTS (with a still-valid code). Days 7–10 — SIV transmission, tax payment, then title dispatch by the Imprimerie Nationale. Any delay on the roadworthiness test, co-owner or code pushes this calendar outside the code’s useful window.

If you are already on day 12 without a valid code, do not force the private ANTS path: switch to an accredited professional with the paper documents, or have the seller resume the declaration.

Seller vs buyer documents: who produces what

The seller remains responsible for the sale declaration and for handing over a correctly crossed-out carte grise. The buyer remains responsible for the certificate application within one month, insurance, address proof and the roadworthiness test. A garage that “handles everything” should still leave you a written trail (receipt, file number). In a dispute, written evidence outweighs oral promises.

For a sale declaration alone, start here. To move straight to the title, open a change of ownership with all scans attached.

FAQ

How long is the code valid?

Practical validity is short (often around 15 days in practice). If the code has expired, you must resume with the seller (new situation) or an accredited professional.

“Code already used”?

A code can only be used once. If an attempt failed after the code was consumed, contact ANTS support or an accredited provider with your evidence.

Is a handwritten transfer enough without a code?

The Cerfa transfer form is essential, but on the private ANTS path the code (or a professional declaration) remains the IT link. Without one or the other, the file stays blocked.

Can I get my carte grise without going through the ANTS?

Yes, via an accredited professional. This is often the simplest route when there is no code. Start a change of ownership on officecartegrise.fr.

Can the seller declare after the 15 days?

Yes, the declaration remains necessary and possible; the delay mainly exposes the seller. The buyer must still aim for the one-month deadline for their title application.

Do I need a code for a classic vehicle or an import?

The French sale logic remains the same if the title is already French. For a foreign vehicle, the central topics are tax clearance / conformity / the import file — not the private ANTS transfer code.

Office Carte Grise supports sellers and buyers: transfer declaration, change of ownership, and unlocking files without a code when the documents allow it.
