Before searching for a generic list of financial centers online, you can save time by directly checking your RIB or your online client space. The affiliated financial center is listed there with its complete address. For clients linked to La Source, the title mentions “La Source Cedex 9, 45900.”

Mail to the 45900 financial center: address and concrete use cases
The La Source financial center handles requests that do not go through the local post office or the digital space. Typically, you send a letter to this center for a dispute over a transaction, an inheritance, or sending requested supporting documents by the management service.
Postal address to use
The standard address is: La Banque Postale, Centre financier, 45900 La Source Cedex 9. It is essential to include your CCP account number in the letter; otherwise, processing will be delayed.
For registered mail with acknowledgment of receipt (in the case of a formal complaint or cancellation), this same address is valid. Keep the receipt as proof of sending.
Situations that require paper mail
- Transmission of original documents (death certificate, notarized power of attorney) in the context of an inheritance or a change of account holder
- Written complaint after a failed resolution via the client space or phone service when you want to formalize the process
- Request for lifting a block or unblocking an account when the advisor at the post office does not have control over the file
In most common cases (transfer, balance inquiry, checkbook order), the online space or mobile app is sufficient. Mail to the financial center remains useful for operations that require legal formalism.
Contacting the La Source financial center by phone
The customer service phone number for La Banque Postale (3639) directs calls to the client’s affiliated financial center. You do not dial a specific number for La Source 45900: the voice server identifies the account and redirects the call to the correct team.
Feedback varies on this point regarding waiting times. During peak periods (beginning of the month, tax periods), the wait time may increase. A few tips can help minimize time loss:
- Call mid-week, between Tuesday and Thursday, rather than at the beginning or end of the week
- Prefer slots in early afternoon, which are generally less busy than in the morning
- Have your account number and client ID ready to speed up identification by the voice server
For simple requests (balance, recent transactions), the automated voice server provides the information without transferring to an advisor. Reserve calls with an advisor for situations that require human intervention.
Online client space and daily management of accounts linked to La Source

Changing financial centers: how it works
A move does not automatically trigger a change of financial center. La Banque Postale conducts internal transfers according to its own distribution logic. The client then receives a letter informing them of the new affiliated center.
In practice, the account number and RIB remain the same. Only the address of the financial center changes in the banking details. There is no action required on your part, except to update your personal postal address with your advisor or through the client space.
The La Source 45900 financial center remains a discreet but central link in the organization of La Banque Postale. For daily management, the digital space covers almost all needs. Paper mail and phone communication retain their usefulness for formal procedures or situations that fall outside the standard framework.
