Lettre Verte vs Registered Letter with AR: which French postage to choose?

Quick answer

Lettre Verte is cheap but has no legal value. Tracked letter proves dispatch, not receipt. Simple registered letter proves delivery to the recipient. Only the registered letter with return receipt (LRAR) sends back a signed written proof of the receipt date — it is the only format admissible in court for a contract cancellation, a formal demand or a tenancy notice.

You need to send an important letter in France but you hesitate between a Lettre Verte, a tracked letter, a simple registered letter or a registered letter with return receipt (AR)? The wrong choice = either you overpay, or your letter has no legal value the day you actually need it. Here is the full comparison.

1. The 4 options at a glance

2. Lettre Verte: for non-critical mail

The Lettre Verte is La Poste's standard service. Cheap, eco-friendly (no air transport), but with no tracking or proof. Use it for:

• A postcard, an informal letter to a relative
• A spontaneous application with no deadline at stake
• Sending non-sensitive documents whose loss would have no consequence

❌ Avoid for: cancellation, formal notice, lease termination, important administrative documents. You have no proof the letter arrived — not even that it was sent.

3. Tracked letter: tracking without legal value

The tracked letter adds a tracking number and proof of posting. You know when and where your letter has moved, but:

• The recipient does not sign on delivery — the letter is simply dropped in the mailbox.
• In case of dispute, you prove sending, not receipt.
• No French law recognises the tracked letter as equivalent to a registered letter.

✅ Useful for: sending a low-value item, following up an important file with no legal implication, reassuring an impatient recipient.

4. Simple registered: proof of delivery

The simple registered letter (R1, R2, R3 depending on the insurance level) forces the postal worker to have the recipient sign on delivery. If no one is home, a notice is left, and the letter is held for 15 days at the post office.

• Proof of posting (receipt kept by the sender)
• Proof of delivery (signature at the office or at home)
• Legally recognised as a registered letter under the French Civil Code

❌ Limitation: you know the letter was delivered, but you receive no written confirmation of it. For that, you need the AR.

5. Registered with AR: absolute proof

The registered letter with return receipt (LRAR) adds a small card that the recipient signs on delivery, and that is physically returned to you. You then hold in your hands:

• The exact date of receipt (which starts all legal deadlines)
• The signatory's identity (recipient or authorised person)
• Proof admissible in court

LRAR is mandatory or strongly recommended for:

• Cancelling a contract (mobile, internet, insurance, gym…)
• Notice to leave a rental
• Formal notice to a debtor or a neighbour
• Contesting a fine, a ticket, a dismissal
• Any letter where the date of receipt starts a legal deadline (Consumer Code, Labour Code, Civil Code)

6. How to choose in 30 seconds

Ask yourself one question: "In case of dispute, do I need to prove the date the recipient received the letter?"

• Yes → Registered with AR. Always. The price difference with a simple registered is minimal, and only the AR protects you.
• No, but I want to track the envelope → Tracked letter.
• No, it's purely informative → Lettre Verte.

7. What about sending from abroad?

All these services are French La Poste services. From abroad, you cannot post a French LRAR directly — you have to either ask a relative back in France, or use an online mail service like MaisonMail, which prints your letter in France and posts it as LRAR in your name. You get the tracking number online, and the scanned AR as soon as it comes back.

Bottom line: for €1 more than a simple registered letter, the AR gives you irrefutable written proof. On a dispute worth several hundred euros (unreturned deposit, post-cancellation debit, contested fine), it is without question the best euro you will ever spend.
