Anyone can update, edit, enhance, or correct an unclaimed business listing in Brownbook.net. Find the business listing, hit ‘edit’, and follow the instructions.
Claimed business listings are locked-down and can only be updated by the claimant. Other users can tag the business, but that’s all; the main business details are under control of the claimant.
Rolling back changes
If you don’t agree with a recent update of a business listing you can roll-back the details to a previous state; on the business listing page you can view previous versions of the listing and choose to roll-back to any one of them. The system actually creates a new copy of the old version.
