Frequently Asked Questions

Where can I find my Adobe Acrobat Pro serial number?

If you purchased a perpetual license directly from Adobe, log in to your Adobe account and check the 'Registered Products' section. If you bought it from a third-party retailer, check your order confirmation email or the back of the physical product box.

Why is Acrobat Pro asking for a serial number when I have a subscription?

This typically occurs if you accidentally downloaded the standalone installer (like Acrobat 2020) instead of the subscription-based version. To fix this, uninstall the current application and redownload Acrobat Pro directly through the Adobe Creative Cloud desktop app.

Can I use Acrobat Pro without signing in to an Adobe account?

For subscription versions, an active sign-in is absolutely required to periodically verify your active license. For standalone versions like Acrobat Pro 2020, you only need to enter the serial number during installation, though an Adobe ID may still be requested for optional product registration.
