MyFoncia centralizes property management for tenants, co-owners and landlords whose properties are managed by Foncia. Updating your contact details in this customer portal seems simple in theory: just a few clicks in your profile settings. In practice, however, the platform distinguishes between information linked to your online account and information held in the agency’s property file, and a change to one does not automatically update the other.
MyFoncia account details and agency file details: two separate processes
The most common source of confusion is the actual scope of an update made online. The MyFoncia customer portal lets you view and edit certain personal details (email address, phone number, postal address) in the profile section. These changes update your digital account, which is used to receive notifications and sign in.
Your property file, on the other hand, is stored in Foncia’s agency management system. It contains the contact details used for your lease, management agreement or condominium service charge notices. An online update does not necessarily update the agency file, which can lead to discrepancies in official correspondence, rent notices or notices of general meetings.
To avoid this, the most reliable approach is to follow up any online change with written notice to the agency. A message sent through the “Requests” section of MyFoncia, or a simple email to your property manager, lets you ask them to update all contractual documents. Before you update your contact details on MyFoncia, it’s best to identify exactly which details need changing and which file they relate to.

Changing your email address on MyFoncia: when things get stuck
Your email address becomes your permanent login ID once your account is activated. Changing it therefore means changing the key you use to access the customer portal. Most users try to do this after switching email providers or losing access to an old inbox.
When you can still access your old email address
If your original inbox is still active, you can change your email address in your profile settings. The platform sends a confirmation link to your old address, followed by another to your new one. You must confirm both emails in succession for the change to take effect. Until you confirm the second email, your old login ID remains active.
When you’ve lost access to your old email address
Things get more complicated when the email account linked to your profile no longer exists. The standard password reset process sends a link to that same address, creating a catch-22. In this situation, the available guidance points users to their Foncia agency, which is the only party authorized to verify the account holder’s identity and link a new email address to the account.
Processing times depend on the agency. The interface does not appear to offer an automated way to get around this issue without human assistance. So it’s best to plan ahead: update your email address before you lose access to your old inbox.
Updating your bank details on MyFoncia
Changing your bank details is mainly relevant to landlords (who receive rent through Foncia) and to co-owners or tenants who pay service charges and rent by direct debit. The customer portal lets you enter new bank details in the payments or financial profile section.
There are several points to keep in mind:
- The new bank details must be for an account in the contract holder’s name. A joint account is generally accepted if the contract holder is named on it, but the agency may reject an account belonging to someone else.
- The new bank details are not always applied as soon as they are entered online. If you make the change too close to the due date, the next direct debit or transfer may still use your old details.
- Ask the agency for written confirmation after entering your new details online. This is the safest option, especially for monthly rent transfers.
Your right to correct personal data and what to do if your request is refused
Updating your contact details is not just a matter of convenience; it also falls under personal data protection law. The right to rectification, established by European regulations, allows anyone to ask an organization to correct inaccurate information it holds, including a condominium manager or property manager.
In practice, if incorrect information remains in your file despite a correction request, you can submit a formal complaint to Foncia’s Data Protection Officer. If you do not receive a satisfactory response, you can contact the CNIL to request that the information be corrected.
This option is rarely necessary for a simple change of address. It may be appropriate when an error in a name, address or account number has financial or administrative consequences, such as service charge notices being sent to the wrong person or direct debits being taken from a closed account.
What to check after making any changes on MyFoncia
Once you’ve updated your contact details in the customer portal, a few checks can help confirm that the changes have been applied throughout the system:
- Log out, then sign back in with your new login details to make sure you can access your account.
- Check the “Documents” section to confirm that future correspondence will show the correct postal address.
- Send a request through the customer portal asking the agency to confirm that your contractual file has been updated.
- Check your next rent notice or management statement to make sure it shows your new bank details.
The MyFoncia platform makes day-to-day management easier, but responsibility for keeping information consistent is shared between the user and the agency. It’s a good idea to document every change in writing, if only to have a record in case of a future dispute.
