Where do I find my activation code? (Readiris 16 & 17)
Depending on how and when you acquired Readiris 16 or Readiris 17, your activation method and code format differ:
1. Standalone Online Purchase Before 2023 (Legacy 34-Character Codes)
If you purchased a standalone license of Readiris 16 or Readiris 17 prior to 2023, your 34-character activation code was delivered in the order confirmation email sent at the time of purchase.
Important Notice Regarding 34-Character Codes:
The legacy activation server dedicated to these older licenses has been permanently decommissioned. Consequently, 34-character codes can no longer be validated, reissued, or activated on new or reinstalled systems.
To continue enjoying uninterrupted OCR and full compatibility with modern operating systems, an upgrade to our latest generation—Readiris PDF 27 (which uses our standard 22-character license keys)—is required.

2. Standalone Online Purchase from 2023 Onward (36-Character Codes)
If you purchased Readiris 16 or Readiris 17 after 2023, your software uses a modern 36-character activation code.
- Where to find it: Located in your purchase confirmation email or within your online IRIS customer account.
- Status: These 36-character codes remain fully supported and active on our current servers. Simply enter the code into the activation window when prompted.
3. Bundled with an IRIS or HP Scanner
If you received Readiris 16 or 17 bundled with an IRIS portable scanner (such as an IRIScan Book, IRIScan Anywhere, or IRIScan Pro) or a qualifying HP scanner, no manual key entry is required:
- Connect your scanner directly to your computer using the USB cable.
- Power on the scanner.
- Launch the Readiris application.
- The software will detect the connected scanner and generate the activation automatically.
- Click "Activate" to complete the setup.
