La Banque Postale login ID is a number assigned when the account is opened. You cannot choose or change it, which makes it difficult to remember. Losing this ID blocks access to online banking, the mobile app and your bank account information.
La Banque Postale ID: what this number represents
Your login ID is different from your bank account number and IBAN. It is a personal number assigned by the bank, made up of several digits, and used solely to access online banking or the mobile app.
This number appears in the welcome letter sent when you open your account. It may also appear on some account statements and on the account management page, as long as your session is active. It is easy to confuse your ID with your account number or password, and this often makes recovery more difficult.
If you have lost your La Banque Postale ID, first check these documents before starting the reset process.
Find your ID in your banking documents
Before contacting customer service, check your paper and digital records for your login ID. Searching your personal files takes just a few minutes and is enough in most cases.
- The letter you received when opening your account (or signing up for online banking) shows your ID, usually in a separate box from the temporary password.
- Some paper account statements include your ID in the header or in a customer information section, depending on when they were issued.
- Your browser’s password manager (Chrome, Firefox or Safari) may have automatically saved your ID when you logged in previously. Check the browser’s “Saved passwords” settings to find it without contacting the bank.
Your browser is the quickest place to look if you have misplaced your paper documents. On a smartphone, the autofill feature may also have saved this information in your system settings.
How to recover your ID online
If you cannot find the information in your documents or browser, La Banque Postale offers a recovery process from the online banking login page. The “Forgot ID / password” link opens a form asking for personal information to verify the account holder’s identity.
The bank then sends your ID by post or through another secure channel, depending on the contact details on file. Your contact details must be up to date for delivery to succeed. An outdated phone number or email address will prevent the process from going through.
Outdated contact details: a common stumbling block
Moving house, changing your mobile number or abandoning an email address can prevent you from receiving the letter or verification text. In this case, online recovery will not work, so you will need to visit a post office or call customer service.
Updating your contact details whenever they change will help you avoid this problem. You can update them directly in online banking (if you can access it) or at a branch.
Finding your ID and strong authentication are two separate steps
Recovering your ID does not necessarily restore full access to all account features. European regulations require strong authentication for certain transactions, including online payments and changes to personal information.
This authentication combines at least two factors from three categories: something you know (a password or code), something you have (a phone or bank card) and something you are (a fingerprint or facial recognition). Knowing your ID only covers the first category.
In practice, after you enter your ID and password, La Banque Postale asks you to complete an additional verification step through the mobile app (push notification) or by text message. Without access to the phone number on file, you will not be able to log in, even if your login details are correct.
Fake bank adviser scams: what you need to know
Scammers target customers who are having trouble logging in. A common tactic involves a phone call from someone claiming to be a bank adviser, offering to “unblock your account” in exchange for your ID or the code sent by text.
La Banque Postale will never ask you to share your ID, password or verification code over the phone. Ignore any request of this kind. The only reliable options are the official website, the mobile app or a post office.
Forgotten password: a separate process from ID recovery
Forgetting your password and losing your ID are two different situations that require separate steps. You can reset your password online from the login page, provided you know your ID and have access to the phone linked to your account.
Resetting your password generates a new temporary code, which you must change the first time you log in. You can change your password, but your ID stays the same: knowing the difference helps you avoid starting the wrong process and wasting time.
If you cannot remember either your ID or your password, recover your ID first (using your documents or by contacting the bank), then reset your password. You cannot complete both steps at the same time online.
A post office is the most direct option if you have lost both details and your contact information is out of date. A branch adviser can restart the entire process after verifying your identity using an official ID document.
