You have just signed a lease or picked up the keys to your new home. Among the list of organizations to notify, your bank is high on the list. For customers of La Banque Postale, updating your address is essential for receiving statements, ensuring the proper functioning of direct debits, and even accessing certain online services.
Proof of residence and regulatory obligations when changing banks
Most guides on changing addresses only describe the steps to follow. They overlook a constraint that can block your account: the requirements related to anti-money laundering (AML-CTF).

Banks, including La Banque Postale, are required to regularly update their clients’ information. When moving, a recent proof of residence is required, not just recommended. An energy bill, tax notice, or home insurance certificate at the new address: the document must be less than three months old.
If you delay in providing this document, La Banque Postale may impose temporary restrictions. Specifically, some transfers may be suspended, access to specific products limited, or even the issuance of a new checkbook delayed. Preparing the proof before even starting the address change procedure at La Banque Postale avoids such inconveniences.

Changing your address at La Banque Postale: the three available channels
La Banque Postale offers several ways to report your new address. The choice mainly depends on your relationship with digital tools and the urgency of the situation.
Online client space or mobile app
This is the fastest channel. From the app or website, go to the “My Profile” section, then “Settings.” The postal address can be modified directly there. Changes are generally processed within a few business days.
However, you will need to provide proof of residence, either by uploading it in the secure messaging of your client space or by submitting it later at the post office.
Appointment with your advisor at the post office
If you prefer a face-to-face exchange, make an appointment with your advisor. Bring your ID and proof of residence. The advisor will update your file on-site and can also check that your insurance contracts (home, auto) linked to La Banque Postale are up to date.
Postal mail
It is still possible to send a free letter to your financial center, accompanied by a copy of the proof. This option is the slowest: expect one to two weeks before the update is effective. Opt for registered mail with acknowledgment of receipt to keep a record of your request.
Main address and correspondence address: an unknown distinction
Have you ever noticed that some bank correspondence arrives at an address different from your home? La Banque Postale allows you to distinguish between two addresses in your file.
- The main address corresponds to your legal residence. This is the one used for tax and regulatory obligations.
- The correspondence address is used for sending account statements, information letters, and bank cards. It may differ from the main address.
This distinction is particularly useful for cross-border clients, people who travel frequently, or those who maintain a second home in France while residing abroad. When you proceed, be sure to specify to the advisor (or in your online space) which of the two addresses you wish to modify, or both.

Checklist after updating your bank address
Changing the address on your current account is not enough. Several elements revolve around your banking file and require separate verification.
- Home and auto insurance contracts taken out through La Banque Postale must be updated independently of the current account. A move can change the home insurance premium, especially if the new home differs in size or location.
- Direct debits (energy, subscriptions, taxes) sometimes use the bank address as a reference. Check with each provider that the change has been reflected.
- If you change departments, your financial center may change. In this case, your login credentials remain the same, but the assigned advisor changes. Ask for confirmation from your new center.
- Consider setting up mail forwarding through La Poste during the transition period. This covers any bank correspondence sent before the effective update.
An oversight on any of these points can lead to a rejected direct debit or the loss of sensitive correspondence (new card code, annual fee statement).
Moving and changing departments: should you change banks?
Leaving your city for another department does not require you to close your account. Your account number, bank details, and payment methods remain unchanged. La Banque Postale, backed by the network of post offices, allows you to carry out most routine transactions at any office across the territory.
However, if you wish to benefit from an advisor close to your new home, request a connection to the local agency or financial center. This process can be done at the post office or by phone. It incurs no fees and does not change your bank details or ongoing contracts.
The real decision criterion concerns physical services: if you regularly use the counter for cash or check deposits, a local connection simplifies daily interactions. For exclusive online use, the question does not even arise.
