FAQs (Unlocking Book Benefits)

Why do I need to upload my purchase invoice?

Many of our books come with additional benefits that are instantly available when you buy a copy from packtpub.com. If you purchased a book from Amazon, O'Reilly, or any other store, we don’t want you to miss out on those benefits. To give you permanent access, we need to verify your purchase. Uploading your invoice is a one-time process that takes just a couple of minutes. Once done, the benefits are yours!

I have a physical invoice. What should I do?

If you have a physical invoice, first scan or photograph it so you can upload it online in a supported format. Make sure the file is either a PDF, JPG, or PNG, and does not exceed 10 MB in size. Place the document on a flat surface with good lighting. If you have a scanner, adjust the resolution settings to balance clarity and file size — 150 or 300 DPI is usually ideal. If you are using an iPhone, you can scan documents through the built-in 'Notes' app. Create a new note, tap the camera icon, and select 'Scan Documents.' Position your phone to clearly capture the invoice and save the scan. You can then export it as a PDF or photo and transfer it to your computer via email, AirDrop, or cloud storage. If you are using an Android device, use Google Drive's scan feature or a third-party scanning app. Start a new scan, align the camera, ensure there’s no glare, and save the scan as a PDF or JPG. To keep the size under 10 MB, adjust resolution settings or use compression tools. Check the file's size and format before uploading. If the file is too large, lower the resolution or compress it. Once ready, you can safely upload the file.

I still can’t find my invoice. What should I do?

Ensure you're signed in with the same account you used to purchase the book, as invoices are tied to the purchasing account. If you still can’t find the invoice, search by the order number or purchase date instead of the book’s title. Also, check your email for any order confirmation or invoice — and be sure to look in your spam or junk folders. If you’re still unable to locate it, contact the retailer’s customer service. They can usually help you retrieve your invoice.

Can I unlock multiple books at once?

No, currently, our system only supports unlocking one book at a time. If you purchased multiple Packt books from our partners, you'll need to unlock each one separately.

How safe is my personal data when I upload my invoice?

We use AI-based validation only to scan your invoice and verify your purchase. Your invoices are never shared with any third party outside of Packt. Your personal data remains safe and secure.

I couldn’t find my book in the search box. What should I do?

If your book is not available via search, please write to us at customercare@packt.com and mention the name of the book you want to unlock.
