Any organisation with a registered office in Belgium wishing to start publishing must first apply to KBR for a publisher’s number. This request can be made during the one-off registration as a depositor at www.depotlegal.be. KBR will enter this organisation in the register of publishers and communicate the number to the publisher. The publisher’s number is needed to compose a legal deposit number.

An author or self-publisher, on the other hand, does not need a publisher’s number.

Good to know! Please note that the publisher number you receive from KBR is not the same as the registrant element issued by an ISBN agency to identify a particular publisher or imprint and forming part of an ISBN number.
