Updating Bank Details

You must inform CAF of any change to your bank account to ensure continued payment of your benefits without interruption. This update can usually be done online, but a written letter remains useful in case of difficulty.

This page explains how to make this update, what information to provide, and offers a ready-to-use letter template, plus a tool to automatically generate your personalized letter.

When should you write this letter?

• You recently changed your bank account;
• You had difficulty updating online;
• You noticed your payments went to an old account;
• You want written confirmation of the update;
• You need to attach a new bank statement (RIB).

In all these cases, a written letter remains a reliable way to update your file.

Required information to include

• Your first and last name and beneficiary number;
• Your new bank account details (RIB);
• The date this change takes effect;
• Never send other sensitive information besides the RIB;
• The list of documents attached (new bank statement RIB).

The more accurate this information is, the more you avoid any delay in receiving your payments.
