The single document
What is the exact list of required documents?
At Gold & Silver Company in Dottignies (Mouscron), the list fits in one line. The rental contract is self-sufficient: no proof of address, no bank statement, no file to build. The opening request is made at the agency, by phone or through the form on the official website, and it comes down to three simple moves: choosing the box size, showing your valid identity document, then signing the rental contract.
To show on signing day
A valid identity card or passport, nothing else.
This rule applies to everyone, Belgian residents or not, individuals or professionals, whatever the nationality.
Card or passport
Identity card or passport: which one to show?
Either one, your choice: a French national identity card is enough, a passport is not required. The habit is simple: check the expiry date printed on the document before travelling, and if it is near or past, show a valid passport instead.
The same document works for every formula. For numbered custody, the non-nominative box at €10 per month, an identity document is shown at signing, as for any rental: valuables are then kept under a number, not in the client's name. The official conditions are on the safe deposit box rental page of the official website.
For two, or for a business
What documents for a proxy or a professional?
The proxy is any adult chosen by the renter. Appointing one is free, and the proxy can be replaced at any time, on simple request.
For professionals, the logic is the same: the person who signs shows a valid identity card or passport, the contract is self-sufficient and is drawn up in the name of the legal entity. A proxy can be appointed free of charge, and replaced at any time.
Elsewhere in Belgium
What do other operators ask for?
Conditions vary from one operator to another. CitySafes, which runs 12 branches in Belgium, requires, according to its official FAQ, "a valid European identification document and an IBAN bank account", the accepted documents being a European passport, a Belgian residence document or a Belgian identity card.
In Dottignies (Mouscron), the list is shorter: a valid identity card or passport, from any country, and no bank account. For a French resident, the process therefore comes down to two words: one document.

Where the question comes from
Why does this question keep coming up on forums?
On MoneyVox, a French consumer forum, savers ask whether a bank requires opening a current account to rent a safe deposit box, and which supporting documents to prepare.
Once the document list is clear, all that remains is the day itself: the walkthrough of the first visit, minute by minute, is detailed on the next page.

Frequently asked questions
Short answers about documents

No. No proof of address, no bank statement and no file to build: the rental contract is self-sufficient, with a valid identity card or passport. This rule applies to everyone, Belgian residents or not, individuals or professionals.
Can you rent with an identity card that expires soon?
The document shown must be valid when the contract is signed: that is the condition set at signing, for any rental.
