Yes. MCAKey LLC is a certified Microsoft Partner and authorized reseller, registered in Montana, United States. Our listing is publicly verifiable on Microsoft AppSource. Every software license key we sell is genuine, sourced through authorized channels, and activates directly through Microsoft’s own servers.

No account is required. Guest checkout works fine — just enter your email address. Creating an account is optional but gives you access to your full order history and makes future purchases faster.

We specialize in genuine Microsoft license keys — Windows activation keys, Microsoft Office, Windows Server, SQL Server, Visual Studio, Visio, and Microsoft Project. We also sell curated software bundles and are expanding into antivirus licenses from publishers like Kaspersky and McAfee. Our goal is to be a trusted source for legitimate software licenses across all major publishers, with Microsoft as our primary focus.

Every key we sell is authentic. As a certified Microsoft Partner, we operate within Microsoft’s own licensing framework — keys activate directly through Microsoft’s servers. No workarounds, no patches, no grey-area tools. The same standard of authenticity applies to every software publisher in our catalog.

Absolutely. We work regularly with PC repair shops, IT service providers, and enterprises that need multiple software licenses. Contact us before placing a large order and we will discuss volume pricing and a delivery arrangement that fits your workflow.

Yes. A PDF invoice is generated automatically with every order. If you need a custom format for your company’s accounting, contact our support team and we will accommodate your requirements.

Your software license key is delivered digitally to the email address you provide at checkout. Nothing to download from our site, nothing to ship, no waiting on a courier. Check your inbox and spam folder if you do not see it within the expected timeframe.

Most orders are fulfilled within 15 minutes of payment confirmation. In rare cases delivery may take up to 2 hours. If your key has not arrived after 2 hours, contact our support team immediately — we will resolve it without delay.

Start by checking your spam or junk folder. If the key is not there after 2 hours, contact us via live chat, WhatsApp, or email with your order number. We will resend immediately. If delivery has not been completed within 48 hours of confirmed payment, you are entitled to a full refund.

No. We sell digital software license keys only. Everything is delivered by email — no shipping fees, no customs delays, and no waiting regardless of where you are in the world.

Go to Settings → System → Activation → Change product key, enter your key exactly as provided, and follow the prompts. Activation completes online through Microsoft’s servers in seconds. If online activation is declined, use our free Confirmation ID tool to complete it without calling Microsoft.

Open any Office application after installation. A prompt will appear asking for your product key. Enter it and sign in with a Microsoft account when prompted. If you run into trouble, our support team will walk you through it step by step.

A Confirmation ID is required when Microsoft’s activation server asks you to complete activation by phone instead of online. This happens with certain volume license keys or when a key has already been activated on another machine. We provide a free online Confirmation ID tool so you can handle this without waiting on hold with Microsoft.

It depends on the license type. A standard single-PC license covers one device. Multi-PC variants cover several. MAK licenses for Windows Server and enterprise products include a defined activation count. Always check the product description before purchasing — or ask us if you are unsure.

Because our products are digital software license keys, we do not offer refunds once a key has been delivered and used. If your key was never delivered within 48 hours of purchase, you are entitled to a full refund. If a delivered key does not work, we replace it — provided you report the issue within 7 days of purchase. Full details are in our refund policy.

Contact support within 7 days of purchase with your order number and a description of the error. We will troubleshoot with you and, if the key is faulty, issue a replacement immediately. Activation support is part of the service — we do not disappear after delivery.
