Build a Military Base Codes (August 2026)

Build a Military Base rewards you with free Premium Crates, buildings, and other goodies just for typing a few words into a text box. You don’t need to grind or spend Robux to snag these bonuses, but you do need the right codes before they expire.

Working Build a Military Base codes

Here’s every code that’s redeeming rewards right now. Copy them exactly as shown, since a stray letter or space will make the code fail.

Note: CARRIERHASARRIVED and CARIERHASARRIVED are two separate entries with different spellings, and both currently work, so try the one that fails first before assuming a code is dead.

How to redeem codes in Build a Military Base

You’ll find the code entry field tucked inside the settings menu, not on some separate codes button, so let your base finish loading first.

Expired Build a Military Base codes

These codes no longer hand out rewards, so don’t waste time typing them in.

How to get more Build a Military Base codes

New codes tend to show up around big milestones, like hitting a like or member goal, or alongside a fresh update to the base-building loop. The developer’s Discord server is where these drops usually surface first, so joining it puts you ahead of the pack when a fresh code goes live.

You can join the official Discord at discord.gg/phantomline, and you’ll find the game itself on Roblox at Build a Military Base.

Why didn’t my code work?

Since there’s no success pop-up, a code that seems to fail might have actually worked. Check your inventory and scan your base for a new crate or building before retyping it, and double-check your spelling and capitalization match exactly what’s listed above.

Check back on this page whenever you log in, since codes here rotate out quietly once the developer decides a promotion has run its course.
