Contact ABN Signal

ABN Signal is an independent site. The team behind it handles corrections, methodology questions, and general feedback directly. Contacting ABN Signal does not create any advisory, legal, or service relationship.

What to contact us about

• Corrections and data concerns — something on the site appears incorrect, outdated, or misleading. See the corrections process for how we handle these.
• Have a question about how data is gathered, compared, or interpreted? The team can walk through the methodology.
• Coverage and scope — you are unsure whether the site covers your particular use case.
• Suggestions for improving explanatory content, guides, or navigation are welcome.

Common questions we receive

"The data on ABN Signal differs from the ABR." — This usually reflects a timing difference. The site refreshes weekly, so recent changes at the source may appear in the next cycle. Let us know and we will check the affected record.

"Can you update an ABN record for me?" — ABN Signal displays public data from the Australian Business Register. To update your own ABN record, visit the ABR or contact the ATO.

"I found an error in a guide or glossary page." — Submit it through the corrections process. The editorial team reviews each report.
