How we check
A row marked Official is the publisher’s own words: its help centre, patch notes, terms of service or an announcement by its staff. Each such row quotes the sentence it rests on, links to the page and gives the day we read it. Wikis, fan sites, videos and generator sites do not count, even when they quote the game; what they say is marked Players report.
Tested by us means we ran the check ourselves. For Roblox we sent each name to Roblox’s own display name check with the birth date of an adult account (2008) and of a child’s (2015), without signing in. We did not type names into the games themselves, so a symbol marked Players report may still be refused on your account.
Most mobile games publish no name rules. For Mobile Legends, Free Fire and Liên Quân, Moonton and Garena publish nothing on length or symbols, and Krafton publishes nothing at all for PUBG Mobile. Epic, Roblox and VNG, which runs Call of Duty: Mobile in Vietnam, publish a length limit; VNG and Roblox’s username rules also list the allowed characters. Ready names that fit each game’s limit are on the pages linked under each game’s name. Fan-made, not affiliated with any of these publishers.
Questions
Which games publish their name rules?
Of the seven, Fortnite, Roblox and the Vietnamese version of Call of Duty: Mobile publish a length limit, and PUBG does so for its PC game only; the Vietnamese version and Roblox usernames also come with a list of allowed characters. Moonton and Garena publish only how to rename and which names are forbidden, and for PUBG Mobile and Liên Quân we found no official rule at all.
Why is my name refused when it fits the length?
Three common reasons: someone already has it (on Fortnite every display name is unique), the game’s filter blocks a word or a character, or a symbol counts as more than one character, as players report for Free Fire, Mobile Legends and PUBG Mobile. Drop one symbol and try again.
How do you know the Roblox names work?
We sent every one of them to Roblox’s own display name check, as an adult account and as a child’s; the Roblox table above gives the count and the day. Roblox can still reset a name later if it breaks the rules, so the check is a snapshot, not a promise.
