Should a Luxembourg brand use the French or the German spelling?

Use the one that appears on your trade mark or business record. If the handle has to match evidence, the spelling on the record is the one to ask about.

Do I need a business in Luxembourg 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 Luxembourg?

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

How do I check whether a username is taken?

Search it on each platform and read the result. The username check guide explains what taken, inactive and available look like.

Username claims in Luxembourg

Names, script and spelling in Luxembourg

Names in Luxembourg often carry é, è, ë, ä or ü. Usernames take plain letters only, so ë becomes e, and ä and ü become a or ae and u or ue. Agree one plain spelling across French, German and Luxembourgish forms of the name and check it on Instagram, TikTok and Snapchat.

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

The GDPR and the Law of 1 August 2018 govern personal data, with the CNPD as regulator, and the Consumer Code covers consumer contracts. Neither decides a username request, which stays with the platform. The price is agreed in euro before work starts, and a failed username claim is covered by the refund policy.

Reference points: trade marks are handled by the Benelux Office for Intellectual Property (BOIP), and personal data by the National Commission for Data Protection (CNPD). These are not legal advice.
