Two worlds coexist today for sending a registered letter without leaving your desk, and they are often confused. On one side, the qualified electronic registered letter (LRE) under the eIDAS regulation, 100% digital from sending to receipt. On the other, the hybrid model — online issuance with paper delivery by a postman — on which Lettre AR is built. Both carry legal value, but with different constraints. Here is our take on Lettre AR in light of this comparison.
The qualified LRE: powerful but demanding
Since January 1, 2019, the qualified LRE under the European eIDAS regulation is the absolute legal equivalent of a paper letter with acknowledgment of receipt (Article L. 100 of the French Code of Posts and Electronic Communications). It’s the only 100% electronic mail, from sending to receipt, with probative force before a court.
Its framework is strict. For an LRE to be valid, it must meet three conditions:
- be routed by a qualified eIDAS provider approved by the ANSSI, with secure servers located in France;
- guarantee verifiable and timestamped sending and receipt dates;
- if the recipient is not a professional, obtain their prior and explicit consent.
The Achilles’ heel: consent of the private individual
That’s where the bottleneck shows. Sending an LRE to a professional does not require any agreement. But to notify a private individual or an administration, obtaining consent is a mandatory legal prerequisite. Without this consent, the transmission is irregular and its evidentiary value can be challenged.
In practical terms, before sending, the issuer must inform the recipient that an electronic registered letter will be sent, and the recipient has 15 days to accept or refuse. If they refuse the electronic format, they can demand a paper delivery. For a private individual who is not comfortable with digital tools—or simply wary—this step often results in a refusal or silence, causing the dematerialized process to fail.
Providers themselves have built “consent managers” and offered paper fallback options to circumvent this obstacle: a sign that the hitch is structural, not incidental.
The hybrid model: the recipient has nothing to do
Lettre AR operates in a different register. The platform dematerializes only the emission phase (drafting, printing, folding, affixing postage, depositing) and entrusts the distribution to the postal network. The recipient receives a real paper letter in their mailbox, delivered by a carrier.
The difference is decisive: no signup, no IT competence required. The registered letter goes through the standard postal channel, with a traditional acknowledgment of receipt. It’s the simplicity of emission that is dematerialized, not the letter itself. This avoids the consent trap that blocks LRE for a private recipient.
Which model for which use?
The choice depends mainly on the recipient:
- Professional recipient, seeking a 100% digital flow: the qualified eIDAS LRE is unbeatable (instant sending, preservation of evidence for up to 10 years, a single rate regardless of the volume of attachments).
- Private recipient, or uncertainty about their digital adoption: the dematerialized paper letter in Lettre AR secures delivery without relying on a prior consent that may never come.
Our view on lettre-ar.com
The LRE and the hybrid registered letter are not competitors but complementary. The former shines in B2B exchanges; the latter removes the major obstacle—the consent of the private individual—that makes the LRE stumble outside the B2B sphere. For a freelancer, a landlord, or a private individual who must notify a third party whose digital habits are unknown, Lettre AR offers the reassurance of a classic paper mail with the convenience of online sending. A pragmatic positioning, best suited for messages where delivery certainty takes precedence over immediacy.
