Check the name first
- 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.
Writing a French name as a username
French names carry accents that the three platforms do not take in a username: é, è, ê, à, ç and ï all become plain letters, and Snapchat’s rule names Latin letters. Plan the plain spelling, and note that Hélène and Helene would then be one username, not two.
What each platform allows
| Platform | What to know |
|---|---|
| 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.
Law and support notes for France
France’s Toubon law requires French in advertising for goods and services offered in France, which matters if the username is shown in a French ad. Data protection falls to the CNIL and consumer matters to the DGCCRF, and a username decision is outside both. A failed claim is covered by the refund policy.
Reference points: trade marks are handled by the French National Institute of Industrial Property (INPI), and personal data by the CNIL. These are not legal advice.
