Every year in France, millions of letters get lost in the weeks following a move. Mail forwarding through La Poste remains the main mechanism to avoid these losses, but its operation has gray areas that deserve careful examination. Actual contract activation, letters excluded from transfer, alternatives for domiciliation: the topic goes far beyond a simple summary of the available offers.
Identity verification and activation of the forwarding contract
Subscribing to a mail forwarding contract online is not enough to trigger the transfer of mail. La Poste now requires the electronic transmission of an identity document to activate any contract subscribed remotely. As long as this document is not validated by postal services, the contract exists but remains inactive.

This distinction between created contract and active contract regularly traps people who subscribe a few days before their move. The announced implementation period (a few working days after subscription) only starts from the validation of identity, not from the order date.
For those who prefer to change their mailing address without unpleasant surprises, the process should ideally be initiated at least two weeks before the actual moving date. This buffer absorbs any potential back-and-forth related to an unreadable identity document or a data entry error.

Verification can be done online, at a post office, or by mail. The digital route remains the fastest, provided you have a clear scan or photo of the document. A selfie or a blurry photo leads to rejection and extends the process by several days.
Administrative mail excluded from postal transfer
The forwarding contract covers the vast majority of shipments: letters, packages, press subscriptions. However, some sensitive administrative mail escapes the system once the contractual period is over.
Tax mail, notifications from the CAF or Social Security require a change of address declaration directly with each organization. La Poste’s forwarding does not replace this process. It complements it during the contract duration but does not automatically extend it.
The concrete trap: a taxpayer moving in September and subscribing to a six-month contract will receive their tax mail forwarded until March. After this date, if the address has not been updated with the tax administration, tax notices or property tax bills will be sent to the old address with no possibility of return.
Organizations to notify as a priority
- The tax office (via the site impots.gouv.fr, section “Manage my profile”), as a delay in declaring the address can lead to lost mail regarding tax deadlines
- The CAF and Health Insurance, whose notifications condition the payment of benefits and the reimbursement of care
- Banks and insurance companies, which send statements, contractual amendments, and cancellation letters to the declared address
- Supplementary pension organizations, often forgotten during the move
Forwarding buys time. It never exempts from updating one’s address with the administrations.
Postal domiciliation and mobile profiles: an alternative to the classic contract
For expatriates, nomadic workers, or people in transition between two homes, La Poste’s forwarding contract has a structural limit: it assumes a fixed destination address. However, these profiles do not always have one.
Postal domiciliation companies offer a permanent address that serves as a reception point. Mail is collected there, digitized, and then transmitted electronically, or physically forwarded as requested. The use of post office boxes and domiciliation addresses is increasing among highly mobile profiles.
A regulatory nuance deserves attention: the address provided by a domiciliation service is a correspondence address, not a tax residence. The user is still required to declare their situation to the tax administration, under penalty of complications during an audit. The available data does not allow for precise measurement of how many people use these services in France, but industry players report an increasing demand.
Duration of the forwarding contract: what choice based on the situation
La Poste offers contracts of varying durations (six months, one year) for national forwarding, and specific formulas for international forwarding. The choice of duration depends less on the volume of mail received than on how quickly all correspondents (administrations, businesses, individuals) will be informed of the address change.
Six months is sufficient when the list of organizations to notify is short and the update can be done in the first few weeks. However, for a household with multiple contracts (energy, telecom, insurance, mutuals, various subscriptions), one year of forwarding provides a significant safety margin.
A often overlooked point: the contract covers the entire household residing at the old address. There is no need to subscribe to a contract per person if all members are moving to the same destination. This information, although present in the offer conditions, escapes many subscribers who pay for multiple unnecessary contracts.
International forwarding: additional constraints
For a move abroad, forwarding remains possible but delivery times are extended. The transfer of bulky packages can also pose problems depending on the destination. Delivery times to Western Europe generally remain reasonable, while shipments to more distant destinations present a higher risk of loss.
Mail forwarding during a change of address works well as a temporary safety net. It does not replace the methodical updating of one’s address with each organization, nor does it serve as a domiciliation solution for profiles without a stable address. Initiating the process early, verifying that the contract is truly active, and updating one’s address with the administrations without waiting for the end of the contract: three points not to be neglected.
