In Halo your name is your Xbox gamertag, so you change it through your Xbox or Microsoft account rather than inside the game — open xbox.com or the Xbox app, go to your profile, and customise your gamertag. Microsoft gives every account one free gamertag change, then charges a fee for each one after that, so it pays to get it right. Modern gamertags are the name plus an auto-assigned suffix (a # and numbers) that keeps tags unique, and they allow letters, numbers and spaces with a 12-character base limit, which means heavy symbol frames usually will not pass the gamertag field itself. Where stylish fonts shine is in supported display areas and clan tags, where small-caps and gothic spellings give a Spartan tag that military edge. Keep it short and sharp so squadmates can call you out during a Big Team Battle without fumbling the name. Everything here is copy-and-paste Unicode, and the cleaner small-caps styles read the same across Xbox and PC. Pick a tough, Spartan-flavoured base and let one accent or a UNSC-style tag carry the rest.

Why choose these? Often used by competitive players who want to look skilled, serious and intimidating.
Gamertag anatomy: the base and the #suffix
Modern Xbox gamertags split into two parts — a base name you choose, up to 12 characters of letters, numbers and spaces, and a #numbers suffix Microsoft appends automatically when your base is already claimed. Original-era tags that never renamed keep their suffix-free name, which is why OG gamertags read as status. Change yours from xbox.com, the Xbox app or the console itself under Profile → Customise; the first change is free and later ones cost a fee, and the new tag follows you into every Halo title on Xbox and PC alike since your Halo identity is the Microsoft account.
The service tag is Halo's built-in flair
Halo gives you a second, sharper identity most players forget: the service tag. In Halo Infinite it's a four-character code stamped on your Spartan's armor and shown in the roster — the UNSC military abbreviation look (S117, NBLE, ODST-style) that no symbol-stuffed gamertag can match for theme. Set it in the game's customization menus and let it carry the lore flavor while the gamertag stays a clean, callable base. In Big Team Battle the name gets said out loud over comms constantly; a two-syllable Spartan-flavored word with small-caps styling in supported display areas wins that fight every time.
Frequently asked questions
How do I change my name in Halo?+
Your Halo name is your Xbox gamertag. Go to xbox.com or the Xbox app → your profile → Customise, and edit the gamertag. The change applies across all Halo titles.
Is changing my Xbox gamertag free?+
Microsoft grants one free gamertag change per account. Each change after that costs a fee, so choose a name you want to keep before you confirm.
Why does my gamertag have a # and numbers?+
The #suffix is auto-assigned when your chosen base name is already taken, keeping every tag unique. Only original tags that were never claimed twice display without one.
What is a service tag in Halo?+
A four-character code (like S117) shown on your Spartan's armor and in the roster in Halo Infinite. Set it in the customization menus — it's the cleanest way to add military flavor.
Do symbols work in Halo and Xbox names?+
Gamertags allow letters, numbers and spaces with a 12-character base and an auto-assigned #suffix, so heavy symbol frames won't pass. Use styled fonts in supported display areas and clan tags instead.
What makes a good Halo name?+
A short, tough Spartan-flavoured base with clean small-caps or gothic styling and at most one accent. Keep it readable so squadmates can call you out in Big Team Battle.
