Do I need an Australian trade mark to claim a username?

No. A trade mark helps only for the intellectual property route. The impersonation route and the previous-username route rest on other facts, and a username that is simply free needs no claim at all.

Can I use the same username on Instagram, TikTok and Snapchat from Australia?

Only if each platform accepts it and it is free on each. Length and characters differ. See same username on every platform.

Do I need a business in Australia to claim a username?

No. A claim can be personal or for a business. What matters is the facts: a name that is yours, a mark, an impersonating profile or a previous username.

How do I start from Australia?

Message us on WhatsApp or email with the username and the profile it is for. Say you are in Australia and what proof you hold.

Username claims in Australia

Names, script and spelling in Australia

Usernames are plain text, so Australian English causes little trouble: no accents and no special letters. The usual snags are apostrophes and hyphens in names such as O’Brien or Smith-Jones. Apostrophes are not accepted on any of the three platforms. A hyphen is accepted on Snapchat as its one separator but not on Instagram or TikTok, so the choice is to join the letters, use an underscore or period, or add a short suffix.

One username on three platforms

Platform	What to know
Instagram	Letters, numbers, periods and underscores, up to 30 characters.
TikTok	Letters, numbers, underscores and periods, and a change is allowed once every 30 days.
Snapchat	3 to 15 characters, Latin letters, numbers and one separator, and a change is allowed once every 12 months.

Read the username rules guide and same username on every platform before you settle on a spelling.

Local rules and what they do not cover

Australian Consumer Law is enforced by the ACCC and state fair trading offices, and the Privacy Act 1988 is overseen by the OAIC. Neither covers a platform’s decision about a username, which stays with the platform. What you send is a username and, where useful, proof tied to the name. Never a password or a login code.

Reference points: trade marks are handled by IP Australia, and personal data by the Office of the Australian Information Commissioner. These are not legal advice.

Before you ask for a claim

See whether the username is taken, inactive or free with the username check.
Settle one plain-letter spelling that fits all three platforms.
Collect proof tied to the name: a mark, a business record or a profile that is posing as you.

The brand and trademark guide covers the proof side.
