Can I look up an ACMA licence number, site or frequency?
Yes. One search box accepts a licence number, ACMA site name or ID, licensee, call sign, postcode, ABN or client number. To search by frequency, use the assignment view and its frequency filters. You can then show the answer as assignments, licences, sites, clients or point to point links.
How is this different from the ACMA's own register search?
The official register searches one kind of record at a time, so a licence result carries licence columns but no frequency, site or antenna, and it offers no summary counts. This tool searches across records at once, lets you choose separately what a row means, counts the result exactly, pages properly and sorts on register columns. The official register does offer column selection, CSV export, a full bulk download, daily change archives and an API, and it remains the reference.
Is the data live?
No. The tool reads a snapshot refreshed from the ACMA bulk data, and every page and exported file shows the snapshot date and its age, read from the refresh log. The display flags the copy when it falls more than a week behind. Where currency matters, check the licence against the official register before acting.
Why can I not see a frequency column when the answer is licences?
A licence usually has many assignments on many frequencies at many sites, so there is no single frequency for the row. The tool hides those columns, says how many were hidden, and points you to the assignment view where they appear. The same applies to site columns at licence grain.
Why does the same company appear twice in the client list?
The register often holds one organisation under several client numbers. The tool shows each client number as its own row rather than guessing which records belong together, and filtering by a licence holder uses the client number rather than the name.
What counts as a link?
A link is a licence with exactly two sites in the point to point subservices. Licences with three or more sites, and two site licences that are not point to point, stay visible in the other views rather than being reshaped into links. The path length shown is the great circle distance between the registered sites, with no terrain or line of sight analysis behind it.
Can I search for licences that have lapsed?
Not usefully from the register itself, because lapsed licences are removed from it within a few months and almost every licence it holds is granted. The change history records lapses and withdrawals observed since recording began, and states the period it covers.
Does the export contain the whole result or just the page?
The export contains the whole result set at the grain shown, up to a row limit. When a result is larger than the limit, the file says so in its preamble along with how many rows matched, so a partial file is never mistaken for a complete one.
Is this a licence enquiry or compliance service?
No. It reports what the register holds and nothing more. It does not say whether a frequency can be licensed, which depends on band plans, service classes, embargoes and coordination rules the register does not carry, and it is not a compliance determination. The ACMA decides licensing matters.
