We receive a letter from Agirc-Arrco requesting proof of residence and a bank account statement within fifteen days. The deadline is short, the personal space displays poorly readable menus, and the scanned document is too large to upload. This scenario appears in most testimonies from future retirees. Submitting supporting documents for complementary retirement should be simple, but several technical obstacles turn the process into an obstacle course.
File size limit on the Agirc-Arrco space: the blockage that no one explains
The most common problem when trying to send a document online is the silent rejection of the file. The Horizon Retraite page confirms this: many insured individuals encounter the rejection of their documents because the files exceed the maximum allowed size, often without an explicit error message. One believes that the submission has failed due to a network issue when it is actually the size of the PDF that is blocking it.

To work around this problem, one can use an online PDF compression tool (like iLovePDF) before uploading. The operation takes less than a minute: you drag the file, retrieve a lighter version, and try sending it again. This advice circulates on several specialized retirement accounts, including in videos, because the official platform does not offer any integrated help on this point.
Before sending anything, it is useful to know how to submit your supporting documents to Agirc-Arrco through the various available channels, to choose the one that fits your situation.

Agirc-Arrco personal space: online submission step by step
The digital submission remains the fastest channel when it works. Here is the concrete procedure from the personal space on the agirc-arrco.fr site.
- Log in to your personal space with your credentials (or via FranceConnect if the account is linked).
- Access the “My Procedures” or “My Documents” section, depending on the version of the interface.
- Select the type of document requested (bank account statement, proof of residence, tax certificate, life certificate) and upload the file in PDF or image format.
- Ensure that each file is less than the displayed limit, and compress if necessary before validating.
Once the submission is made, you generally receive an acknowledgment of receipt in your personal space. Feedback varies on this point: some insured individuals report a delay of several days before the document appears as “processed” in the tracking.
When online submission does not work
After a period of gradual retirement, the personal space does not always allow for document submission online. Several recent testimonies confirm this limitation. In this case, sending a registered letter remains the only reliable option to secure the file and keep proof of sending.
You then send the documents to the management center address indicated in the request letter. Each complementary retirement fund has its own postal address, and you should not send it to the national headquarters by default.
Quality of submitted documents: what speeds up or blocks processing
Agirc-Arrco emphasizes a point that insured individuals underestimate: a poorly scanned document can lead to rejection and prolong the procedure by several weeks. Retirement advisors remind that a blurry, cropped, or low-resolution proof will be systematically refused.
Specifically, when scanning a document with a smartphone, it is better to use a scanning app (like Adobe Scan, Genius Scan) rather than the regular camera. These apps automatically straighten the document, adjust the contrast, and generate a clean PDF.

The most commonly requested documents
The type of proof depends on the situation (first retirement request, file update, annual life certificate for residents abroad). In practice, recurring documents are the bank account statement, identity document, last tax notice, and proof of residence dated within the last three months.
For a survivor’s pension request, the death certificate and family record book are added. Each document must be fully readable, including corners; otherwise, the file will be returned.
Agirc-Arrco voice server and phone: follow up on a blocked file
When a submission goes unanswered for more than two weeks, you can contact Agirc-Arrco by phone. A voice server is available at all times to obtain information about the status of your file or to have certain letters reissued.
To speak to an advisor, you must call during the opening hours of the management center linked to your file. The number is listed on the last letter received or in the personal space, under “My Contacts.”
- Have your social security number handy before calling.
- Prepare the reference of the document request letter (date and file number).
- Request an explicit acknowledgment of receipt if the advisor confirms that the documents have indeed been received.
This phone channel remains the most effective for unblocking a situation where the online space malfunctions or when documents have been sent by mail without response.
The submission of supporting documents to Agirc-Arrco relies on three channels (online, mail, phone), but none is perfect in all cases. The reflex that saves time: compress your PDFs, scan cleanly, and keep a copy of each submission with its date. A complete and readable file from the start avoids the back-and-forth of follow-ups that can delay the payment of the complementary pension by several months.
