I just bought Office. Where do I enter my product key?

If you bought a new, never used product key

If you have a new, never used product key, go to www.office.com/setup and follow the on-screen prompts.

If you bought Office through the Microsoft Store

If you bought Office through the Microsoft Store, you can enter your product key there.

1. Go to www.microsoftstore.com. In the upper right-hand corner, select Sign in and enter the user ID and password you used to buy Office.

2. After you sign in, select your name in the upper right-hand corner, and then select Order History.

3. Locate the Office one-time purchase or individual Office app, and then select Install Office to view your product key (this doesn't actually install Office).

4. Select Install Office again in the window where the product key appears.

5. On the Hi. Let's get your Office page, follow the prompts to associate your product key with your Microsoft account and start the installation process.

1. Start any Office app, such as Word, Visio, or Project, depending on your purchase.

2. In the Sign in to set up Office screen, select I don't want to sign in or create an account (it's a small link at the bottom of the window).

My new Windows 10 PC came with Office but I can't find a product key

If you see a Let's get started screen with options to try, buy, or activate Office, this means that Office is installed on your new PC as a 1-month trial of Office 365 Home. You won't receive a product key from your PC manufacturer unless you paid for an Office product key card. Instead, you can start a trial of Office 365 Home, or buy Office.

If you paid for an Office product to be included on your new Windows 10 PC, a digital product key is transmitted to your PC when you activate Windows 10. You won't receive a printed product key. Instead, you'll see a message similar to the following when you start Word (or any Office app).

I bought a product key card but there's no key on it

If you bought an Office product key card, you might need to carefully scratch off a silver foil coating on the back of your product key card to reveal your product key. If you damage the key while scratching off the foil coating, see I lost or damaged my product key.

Tip: A product key card might also contain bar codes and other groups of letters and numbers, but the product key will always be shown in the format XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.

Office is prompting me for a product key

Product Id Key Finder

Use your Microsoft account, not your product key, to install and activate Office and individually purchased Office apps, such as Project, Visio, Word, Excel, and Outlook.

Sign in to install Office

Bookmark the site below so you always know where to go to install Office.

Sign in to activate Office

If an Office app prompts you to activate, sign in with your Microsoft account instead of a product key.

Use the right Microsoft account

Make sure you sign in with the Microsoft account that you used to buy Office.

Note: If you bought a new, unused Office 365 product key card to renew an Office 365 subscription or to buy your trial, you can enter that product key if Office prompts you for it. You can also enter the product key at www.office.com/setup.

There are a few exceptions where you'll need to do something other than sign in.

• If you bought Office Professional Plus, Visio Professional, or Project Professional through your employer's Microsoft HUP benefit, you'll need your product key to install Office on a PC. To locate your product key online, see Get your HUP product key.

• If you're using a volume license version of Office Professional Plus at work, you'll need to contact your admin for a product key.

• If you see a yellow or red banner in an Office app that says SUBSCRIPTION EXPIRED, you must renew your Office 365 subscription to keep using Office. For help, see Renew Office 365 for home.

• If Office came pre-installed on your new device, and you see a yellow or red banner in an Office app that says PRODUCT NOTICE Most of the features of <app> have been disabled because it hasn't been activated, you must start a new Office 365 Home trial, sign in with a Microsoft account that's associated with Office, or buy Office. For help, see Activate Office.

• If you bought Office Professional Plus online, see Can I buy a product key? or, if your product key isn't working, see My Office product key isn't working.

Do I need a product key to reinstall Office?

No, you don't. Just go to the Microsoft account, Services & subscriptions page and sign in using the Microsoft account that you used to buy Office. We can help if you forgot your Microsoft account or password.

Note: You need a product key to reinstall Office Professional Plus, Visio Professional, or Project Professional through Microsoft HUP. For help, see Get help installing Office through Microsoft HUP.

Can I change my product key?

Yes, you can change the product key for Office Home & Business, Office Home & Student, Office Professional, and individually purchased Office apps. To learn how, see Change your Office product key

You can also switch your Office license if you buy a different version of Office. For example, if you have Office Home & Business and decide to subscribe to Office 365, you can switch your existing install from Office Home & Business to Office 365. To learn how, see Switch your Office license.

Can I view my product key in Office?

No, you can't. For security reasons, the full product key isn't displayed within Office.

Instead, for Office 365, Office 2019, and Office 2016, you can view the Microsoft account that Office belongs to. This account takes the place of your product key and can be used to reinstall Office from the Microsoft account, Services & subscriptions page and to activate Office.

To view the Microsoft account that Office belongs to, open a document in Word (or any Office app) and go to File > Account. Look for the email address after Belongs to below the product name.

Can I view my product key online?

If you bought Office 365 or Office Home & Student

Your product key isn't displayed online. If Office is prompting you for a product key, you can sign in using the Microsoft account that you used to buy and download Office.

If you bought Office Home & Business, Office Professional, and individual Office apps

Product keys for one-time purchases of Office Home & Business, Office Professional, and individual Office apps are available at the Microsoft account, Services & subscriptions page. However, you don't need a product key to reinstall or activate these products. If these products are prompting you for a product key, you can sign in using the Microsoft account that you used to buy and download Office.

If you still want to view your product key, here's how:

1. Go to the Microsoft account, Services & subscriptions page and sign in, if prompted.

2. Select View product key. Note that this product key won't match the product key shown on an Office product key card or in the Microsoft Store for the same purchase. This is normal.

If you bought Office through Microsoft HUP

If you bought Office Professional Plus, Visio Professional, or Project Professional through your employer's Microsoft HUP benefit, you can also view your product key online on your Order Details page. For help, see Get your HUP product key.

Can I view my key in the Microsoft Store?

If you bought Office Home & Student, Office Home & Business, Office Professional, or individual Office apps from the Microsoft Store and you haven't installed them yet, you can also view their product keys and install them from the Microsoft Store.

Here's how to view your product key in the Microsoft Store:

1. Go to www.microsoftstore.com. In the upper right-hand corner, select Sign in and enter the user ID and password you used to buy Office.

2. After you sign in, select your name in the upper right-hand corner, and then select Order History.

3. Locate the Office one-time purchase or individual Office app, and then select Install Office to view your product key (this doesn't actually install Office). Note that this product key won't match the product key shown in the Microsoft account, Services & subscriptions page. This is normal.

My product keys don't match

This is normal. The Office product key shown on the Microsoft account, Services & subscriptions page will always be different than the product key that's shown on a product key card or email receipt. They are two different types of keys, even though they use the same format.

Can I buy a product key?

It depends on what you're trying to do.

• To buy a brand new copy of Office, or start a new Office 365 subscription, you can buy an Office product key card from a retailer. You can redeem your key at www.office.com/setup to set up your Microsoft account and install Office. You can also buy a digital download directly from the Microsoft Store at www.microsoftstore.com. You'll receive a product key if you buy a one-time purchase Office or individual Office apps, but you won't need or receive a product key for Office 365.

• To renew your Office 365 subscription, you can buy an Office 365 product key card from a retailer and redeem the key at www.office.com/setup. You can also renew your subscription online, without a product key, at www.office.com/renew.

• If Office is prompting you for a product key, and you want to buy a product key to activate Office, it's better to uninstall your current version of Office and then buy and install a new version of Office from the Microsoft Store. This way you can be sure that Office will activate successfully.

My Office product key isn't working

If you see an error message when you redeem your product key at Office.com/setup, see Get help with product key errors on Office.com/setup.

If your Office product key doesn’t work, or has stopped working, you should contact the seller and request a refund. If you bought a product key separate from the software, it’s very possible the product key was stolen or otherwise fraudulently obtained, and subsequently blocked for use. Unfortunately, there are many dishonest sellers who offer stolen, abused, or otherwise unauthorized Microsoft product keys for sale. Sometimes these product keys are printed on counterfeit labels or cards with a download link to Microsoft software, and sometimes they’re distributed with software media that is unauthorized for resale, such as promotional media, original equipment manufacturer reinstallation media, or other Microsoft program-specific media.

Contact support about my product key

If you’ve followed the guidance in this article and still need help, visit our Microsoft support page for assistance.

Depending on how you purchased your Adobe Student & Teacher edition product, you may have received a serial number or a redemption code.

You’ll need the serial number to register your product, update your product, upgrade to a Creative Cloud plan, or qualify for certain types of service plans. Use the redemption code—sent in less secure situations—to redeem your product license and get your serial number.

No serial number is needed for subscription or membership products. Simply sign in with your Adobe ID to activate your membership.

If you purchased a stand-alone version of a product—via a card, as a download, or on discs in a box (for example, Acrobat XI, Photoshop Elements, or Lightroom 6)—you will need your serial number to install the app. Enter your serial number when prompted during the installation of your app.

If you registered your product or downloaded it from Adobe.com, finding your serial number is simple. Adobe keeps track of it for you.

To see a list of your registered products and their serial numbers, sign in with your Adobe ID and password.

Note:

Having trouble with your Adobe ID? See Adobe ID, sign-in, and account help.

Click the Planstab, and then click My products in the left pane. A list of your registered products and serial numbers is displayed.

Serial number not showing up in your Adobe account?

Check the following table to find your serial number.

How did you receive your product?	Find your serial number:
In a product box.	Printed on the disc or disc sleeve. Note: For Elements products, the serial number is located on the Windows DVD sleeve.
As a download from Adobe.	In an email from Adobe containing the serial number for the product you purchased. Look for the subject line 'Your Serial Number' or 'Your Serial Numbers.'

Redeem products purchased from a store or online retailer

No serial number is needed for membership or subscription products such as Creative Cloud - Student and Teacher plan. Simply sign in with your Adobe ID to activate your membership.

If you purchased a membership from a retailer, however, you may have received a redemption code—for example, beneath the scratch-off foil on the back of a prepaid card. If you have a redemption code, follow the steps below to redeem your code and activate your membership.

Redeem a redemption code to activate your membership.

Go to creative.adobe.com/educard and do one of the following:

• Have an Adobe ID? Enter it and your Adobe password, and click Sign In.

• Don't have an Adobe ID? Click Sign Up and follow the onscreen instructions.

Enter the required information regarding your academic status and click Continue.

Enter the 24-digit alphanumeric redemption code and click Activate Membership.

Note:

Redemption codes contain both letters and numbers. The other numeric codes such as the UPC code on your insert, card, or email are not your redemption code.

Read the renewal plan terms and click Accept Terms & Conditions.

If prompted, enter billing information and click Continue.

In the window that appears, click Get Started again.

You now have access to the apps that are included in your membership plan. Click Open the Creative Cloud app to start downloading your software.
