Build a Military Base Codes (September 2026)

Build a Military Base is the Roblox base-building game where you construct, upgrade, and defend your own installation. The developer regularly drops codes that hand out Premium Crates and, occasionally, entire buildings like a Research Lab or Logistics Warehouse, straight into your base.

Working Build a Military Base codes

Here’s every code that’s currently redeemable, along with what you’ll get for typing it in.

Note: CARRIERHASARRIVED and CARIERHASARRIVED are two separate codes with different spellings, so type each one exactly as shown if the first doesn’t go through.

How to redeem codes in Build a Military Base

Redeeming codes here doesn’t involve a pop-up window or a separate website, so you’ll want to have your base loaded up before you start typing.

You can try this on the Build a Military Base Roblox page if you haven’t installed the experience yet.

Expired Build a Military Base codes

These codes have already been used up or pulled by the developer, so don’t waste time typing them into the Settings box.

How to get more Build a Military Base codes

Looking at the naming pattern, most codes tie into like-count milestones, member-count milestones, or the release of a new feature (a mech, a boss, a new building), so fresh ones tend to show up whenever the game hits a new number or ships an update. The safest place to catch these the moment they drop is the official Build a Military Base Discord server, where the developer posts them directly.

It’s worth checking back after any big update or milestone announcement, since that’s typically when a new batch gets released.

Are these codes free?

Yes. Every code listed here is free to redeem and doesn’t require any purchase or Robux.

Why didn’t my code work?

Double-check that you typed the code exactly as shown, including capitalization, into the “Insert Codes Here” box under Settings. If it’s listed in the expired section above, it’s simply been retired and won’t go through anymore.

Keep this page handy and swing back by whenever you hear about a new update, that’s usually your cue that fresh codes are on the way.
