A lost survey code blocks the submission of the form and, depending on the type of survey, exposes the respondent to a deadline breach. The recovery procedure depends on the authentication channel used during the initial registration: MyGuichet.lu account, postal identifier, or sector portal. Here we detail the technical recovery mechanisms and the pitfalls that prolong processing.
Authentication linked to the MyGuichet account and recovery of the survey code
The gradual migration of surveys to MyGuichet.lu changes the recovery logic. The survey code is no longer an autonomous identifier: it is linked to the user.lu account of the respondent. Losing the code without losing access to the account simplifies the process, because the code remains accessible in the form history of the MyGuichet dashboard.
The problem arises when the respondent has lost both the survey code and their MyGuichet credentials. In this case, resetting the MyGuichet password must precede any request for code resending. Attempting to contact the survey helpdesk directly without account access prolongs processing, because the helpdesk requires identity verification that goes through the same account.
For agricultural and viticultural surveys submitted via MyGuichet.lu, the Ministry of Agriculture has set April 15, 2026, as the submission deadline. A lost code recovered after this date no longer allows for regularization without additional procedures. We recommend storing the survey code in the MyGuichet digital vault upon receipt, even before filling out the form.
To understand the detailed steps for recovering credentials related to satisfaction surveys, the Ecostart help guide outlines each step of the process applied to the BK Vous Écoute portals.
STATEC survey helpdesk: single channel for postal codes
The STATEC survey portal (Statistics Portal) imposes a strict rule: the survey helpdesk indicated on the invitation letter is the only valid channel. Using the generic contact form of STATEC or sending an email to a standard institutional address does not trigger the resending procedure.
The paper invitation letter contains a reference number distinct from the survey code itself. This reference number helps the helpdesk locate the file. Without this number, the identification of the respondent relies on the establishment number or tax ID, which prolongs verification.
Common mistakes that delay resending
- Contacting the STATEC switchboard instead of the dedicated survey helpdesk: the request is redirected, adding several business days to processing.
- Creating a new account on the survey portal instead of requesting a resend: the system then generates a duplicate that complicates matching with the initial survey.
- Sending the request from an email address different from the one registered during the first login: the helpdesk cannot validate the requester’s identity without matching addresses.
STATEC does not offer automated recovery via SMS or reset link. Each request is processed manually, which explains a variable delay depending on the helpdesk’s workload.
Regulatory deadlines and risk of forfeiture in case of lost code
The loss of a survey code does not suspend the legal deadlines for submission. For rural aid, aid and payment requests must be submitted within a specified timeframe, often set at three years, under penalty of forfeiture. A respondent who loses their code and delays recovery is therefore at risk of losing rights if the deadline falls during the recovery period.
This constraint is particularly sensitive for agricultural structural surveys. The online form via MyGuichet.lu has become the only accepted mode of transmission for declaring agricultural areas. No paper substitute version is provided in case of digital blockage related to a lost code.
Technical anticipation to avoid loss
Several measures reduce the risk upstream:
- Photograph or scan the invitation letter upon receipt and store it in a secure space separate from the main email inbox.
- Associate the survey code with a professional password manager, entering the STATEC reference number as a secondary identifier.
- Check, before each survey period, that the email address linked to the MyGuichet account is still active and accessible.
Sector surveys outside STATEC: specific operation of each portal
Customer satisfaction surveys (like BK Vous Écoute) and private sector surveys use proprietary authentication systems, unrelated to MyGuichet.lu or STATEC. The survey code plays a different role here: it serves both as an identifier and a unique access token.
On these portals, recovery goes through the customer service of the issuing company, not through a public administration. The receipt, invoice, or solicitation email generally contains the code. Without this document, most portals offer a recovery form that verifies the email address or phone number associated with participation.
The distinction between mandatory public surveys and optional private surveys is technical but crucial. A public survey not submitted on time leads to administrative consequences. An incomplete private survey simply results in the loss of a potential promotional advantage. Recovery procedures reflect this difference: the public helpdesk requires formal identity verification, while private customer service often settles for email confirmation.
Regardless of the type of survey, the rule remains the same: never recreate access from scratch before exhausting the recovery procedure for the existing code. A duplicate account, in both public and private contexts, generates inconsistencies in databases that complicate any subsequent regularization.
