If your purchase of Office 365, Office 2016, or Office 2013 came with a product key, you enter your key at Office.com/setup. After you enter your key, you can download and install Office.
If you have an existing Office 365 subscription, you can use your product key to renew your subscription.
Did you know? If you already entered a product key and you're trying to install or reinstall Office, you don't have to enter your product key here again. Just go to Install Office on your PC or Mac and follow the steps to reinstall Office. If you can't find your product key, see Find your Office product key.
A Microsoft account is required to redeem your product key. With a Microsoft account, you'll be able to reinstall Office later, without the need for your product key.
If you already sign in to a Windows PC, tablet, or phone, Xbox Live, Outlook.com, or OneDrive, you already have a Microsoft account. Use that account instead of creating a new Microsoft account. If you have an existing Office 365 subscription, be sure to sign in with the Microsoft account that's associated with your subscription (we might detect it for you).
If you create a Microsoft account, you can use any email address as the user name for your new Microsoft account, including addresses from Outlook.com, Yahoo! or Gmail.
Here are some important notes about Microsoft accounts:
Your Microsoft account can have only one subscription associated with it. If you use the same Microsoft account to buy or redeem multiple Office 365 subscriptions, you extend the amount of time for your subscription, up to a maximum of 5 years. This doesn't increase the number of devices you can install Office on or increase the amount of online storage that's available with the subscription. For more information, see What happens if I add another Office 365 for home subscription plan to my account?
If you have Office 365 Home and need to install Office on more than 5 PCs or Macs, or 5 phones or tablets, you must start a new Office 365 Home subscription when you redeem your product key. You can do this by creating a new Microsoft account or by using an existing Microsoft account that's not associated with an Office 365 subscription. If you need to support more than 5 users, we recommend purchasing an Office 365 business subscription or volume license products of Office instead.
You can redeem up to 30 one-time purchases of Office 2013 or Office 2016 on the same Microsoft account. If you'd like to purchase more than 30 copies of Office for work, we recommend purchasing an Office 365 business subscription or volume license products of Office instead.
To enter your product key, type 5 digits of your product key into each box. Just type the letters and numbers, not the hyphens. Verify your country and region and your language, and then select Next to continue. If you get an error, see the Product key errors tab above.
Your 25-character product key should look something like this:
The next steps in the process can vary. Just follow the on-screen prompts to complete the process. For example:
If you're setting up a brand new Office 365 subscription, you can configure automatic renewals.
If you're renewing an existing Office 365 subscription, you'll go through the renewal process.
If you're redeeming a product key for Office Home & Business or Office Home & Student, you won't see any prompts for subscription renewals since these are one-time purchases of Office.
Here are some additional tips about entering your product key:
If you have multiple product keys and want to add more than one year to your subscription, go back to Office.com/setup and repeat the renewal process for each additional key.
If you enter a product key that you have already redeemed, your web browser will redirect to https://office.com/myaccount page after you enter the key.
After you enter your product key, your current country or region might not appear in the list. This can happen if you buy your product key in a different country or region than where you redeem it. Your product key is only valid for the countries or regions listed. If you need assistance, contact Microsoft support.
Check this list if you get an error when you enter your product key.
Sorry, we can't find this product key in our database (ERR_INVALID_TOKEN) or Sorry, we can't set up your account at the moment (ERR_MISSING_PARTNUMBER or ERR_PKPN_DETAILS_NOTFOUND)
You'll see this error message if you enter a product key for a version of Office that isn't available for download from Office.com/setup. Here's where you can enter those product keys.
For Office 2010, Office 2007, and Office 2011 for Mac go to Microsoft.com/software-download/office.
For Office 365 Business Premium, go to https://office.com/setupkey.
If your product key doesn't work on these sites, it might be a volume license key. Volume license keys are typically used by organizations to activate volume editions of Office Professional Plus. If you have a volume license key, please contact your administrator for help with installing Office or see Activate volume editions of Office to activate Office Professional Plus using a product key.
The product key isn't valid (INVALID_PRODUCT_KEY or ERR_INVALID_TOKEN)
You'll see this message along with either error code INVALID_PRODUCT_KEY or error code ERR_INVALID_TOKEN if you enter the wrong product key, or if you have a typo in your product key.
Examples of using the wrong product key
Most Microsoft products use a 25-character product key. If you own multiple Microsoft products, it’s easy to confuse the keys and use the wrong one. Here are some common things that can happen:
Using the product key from a sticker on a PC
These product keys are normally for Microsoft Windows. Check the sticker for a product name to make sure it’s for the Office product you’re trying to install.
Using product keys for Office 2010 or earlier
For Office 2011 for Mac, Office 2010, or Office 2007, go to Microsoft.com/software-download/office.
Using on Office 365 for business product key
These product keys are entered in a different location. For help, see Enter your product key for Office 365 for business.
Using the product key provided by a school or organization
If your school or organization has a volume license agreement for Office, then you are using a different version of Office that uses volume license keys. These keys can’t be used for retail Office versions like Home and Student, Home and Business, or Professional, and can't be entered on this page. See Activate volume editions of Office for more information.
Common ways people mistype the product key
Reading the product key from a label can be difficult. Letters and numbers may look the same.
To avoid typing mistakes, here’s a list of commonly mistyped characters:
The letter B and the number 8.
The letter G and the number 6.
The letter O and the number 0.
The letter Q and the number 0.
The letters V and V back to back (VV) appear like the letter W.
Tip: If you bought Office from an online retailer and received a confirmation email, try copying and pasting the product key from this email instead of typing it.
The product key isn't valid (KEY_NOT_ACTIVATED)
You'll see this message if the retailer where you purchased Office didn’t activate the product key at the point of sale. The product key must be activated by the retailer before you can use it.
To resolve the issue, go back to the store where you purchased Office and have them activate the product key.
This product key isn't meant for your region
If you get this message, this means that your product key was purchased in a different country or region than where you're currently located. Office product keys must be redeemed in the country or region where they are purchased. If you need assistance, contact Microsoft support.
Sorry, we can't set up your account right now. Hang on to your product key, and try again later (ConversionBlockedSubscriptionViolations)
