Microsoft Word shows its product name, version number, build, and 32-bit or 64-bit status in the app’s Account or About screen.
You usually need your Word version for one reason: something isn’t matching the instructions on your screen. A menu looks different, a feature is missing, or an update changed the layout. Once you know the exact edition, the rest gets easier.
There are two things to identify. The first is the product name, such as Microsoft 365, Office 2024, Office 2021, or an older one-time purchase. The second is the app version and build number, which tell you the release track you’re actually running right now.
This is where many people get tripped up. Word can say “Microsoft 365” and still have a different build from another PC. That’s normal. The label tells you the product family. The version and build tell you the current app release.
What Version of Word Do I Have On Windows And Mac?
If Word is installed on your computer, the fastest path is inside the app itself. Microsoft’s own instructions point to the Account area on Windows and the About Word window on Mac. That gives you the product name first, then the version details.
On Windows
- Open Word.
- Click File.
- Select Account. On some older releases, you may see Help instead.
- Under Product Information, read the product name.
- Click About Word to see the full version number, build, and whether it’s 32-bit or 64-bit.
If you’re helping someone else remotely, ask them to read back the full line from the About box, not just “Word 365.” That extra build number often explains why two computers behave differently.
On Mac
- Open Word.
- Click Word in the top menu bar.
- Select About Word.
- Read the version number and license details in the dialog box.
Mac users often stop after seeing “Word for Mac.” Don’t stop there. The version line matters more than the app name when you’re matching menus, fixes, or feature rollouts.
Finding Your Word Version On Every Device
Desktop Word is only part of the story now. Some people are using the browser version, some are on mobile, and some switch between all three in the same week. The way you identify each one is a bit different.
Word For The Web
If you open documents in a browser from Microsoft 365, OneDrive, or SharePoint, you’re using Word for the web. You won’t see the same desktop-style About box because it isn’t a locally installed copy of Word.
In that case, the answer is simple: your version is Word for the web. Microsoft treats it as the browser edition, with its own feature set and a different update flow from the desktop apps.
Word On iPhone, iPad, Or Android
On mobile, you’re using the Word app from the App Store or Google Play. The app store listing and the in-app settings page usually show the app version. That number helps with bug reports, but it does not map neatly to Office 2021 or Office 2024 the way desktop releases do.
Older Copies Of Word
If the Account menu is missing or the screen looks dated, you may be on an older perpetual release. In those cases, the About window is still your best bet. It can reveal names like Word 2016, Word 2013, or Word 2010.
Microsoft’s About Office version instructions also note that the Account page can show the installation type, such as Click-to-Run or Microsoft Store, which can help when reinstalling or repairing Office.
What The Names In Word Actually Mean
Once you find the label, you still need to decode it. “Microsoft 365” is a subscription. “Office 2024” is a one-time purchase. “Word for the web” is the browser edition. Those names sound close, but they behave differently.
Microsoft lays out the split between subscription and one-time purchase in its comparison of Microsoft 365 and Office 2024. That matters because feature timing, update cadence, and account access can differ quite a bit.
| What You See In Word | What It Usually Means | What To Expect |
|---|---|---|
| Microsoft 365 | Subscription desktop apps | Ongoing updates, changing build numbers, account-based license |
| Office 2024 | One-time purchase desktop suite | Fixed product generation with standard updates |
| Office 2021 | Older one-time purchase desktop suite | Same general idea as Office 2024, fewer newer features |
| Word for the web | Browser-based edition | No local install, different feature set, web-based updates |
| Word for Mac | Desktop app on macOS | Version shown in About Word, license shown in the dialog box |
| Version 16.xx | Internal app version line | Common across several modern Word releases, so read the product name too |
| Build number | Specific release of the app | Useful when a feature appears on one device but not another |
| 32-bit or 64-bit | Installation architecture | Matters for add-ins, macros, and some troubleshooting steps |
Why Your Version Number Can Still Be Confusing
The messiest part is the version number format. Many modern releases use version 16.x somewhere in the details. That does not mean every copy is the same age. A Microsoft 365 install and a one-time purchase can both show a 16.x line while still being different products.
That’s why you should always collect four details together: product name, version number, build number, and 32-bit or 64-bit status. Leave out one of those and the answer can stay fuzzy.
What To Tell Tech Support Or A Vendor
- Product name: Microsoft 365, Office 2024, Office 2021, and so on
- App name: Word
- Version and build
- Windows or Mac
- 32-bit or 64-bit, if shown
That five-part description is usually enough for a clean answer on compatibility, add-ins, missing buttons, and file behavior.
Common Situations And The Right Answer
Plenty of searches for this topic are really about a hidden problem. Someone doesn’t just want the version. They want to know why their screen looks old, why a template won’t open, or why a tutorial doesn’t match.
Here’s the plain-English answer for the most common cases.
| If You Notice This | It Usually Points To | What To Check Next |
|---|---|---|
| No Account menu in Word | Older desktop release | Open About Word or look under Help |
| Using Word in a browser tab | Word for the web | Expect different menus and fewer desktop-only tools |
| Tutorial shows buttons you don’t have | Different build or edition | Compare product name and build number |
| Add-in won’t install | 32-bit vs 64-bit mismatch | Read the About Word dialog carefully |
| One PC says Microsoft 365, another says Office 2021 | Different license model | Match the instructions to each product family |
| Mac steps don’t match Windows articles | Different interface path | Use Word > About Word on Mac |
Fast Ways To Tell Which Word You’re Running
If you only need the answer in ten seconds, use this shortcut list.
Desktop Shortcut
- Windows: File > Account > About Word
- Mac: Word > About Word
Browser Shortcut
If Word opens inside Chrome, Edge, Safari, or another browser without a local desktop window, you’re using Word for the web.
Store-App Shortcut
If you only use Word on a phone or tablet, check the app settings or store listing for the app version. Treat that as the mobile app version, not a desktop Office generation.
What To Do After You Find The Version
Once you have the version, save it somewhere easy to reach. A screenshot of the About box is enough. That gives you a clean record the next time you need help, reinstall Office, or compare two machines.
If the version is older than you expected, sign in to the Microsoft account tied to your Office license and check whether you’re using the right install. If the menus still don’t line up with current articles, you may be on an older perpetual copy or on Word for the web instead of the desktop app.
The main thing is this: don’t guess from the icon, the ribbon color, or the file type. Word itself will tell you the exact edition. Open the app, read the product line, then read the About box. That’s the clean answer.
