Email, encryption, and other protections

Any time you send or receive a PayPal payment, we'll send you an email to confirm the transaction. If you ever receive a confirmation email for a transaction you didn't make, alert us right away and we'll launch an investigation.

There are a lot of reasons more than 150 million account holders trust us with their financial information, and data encryption is one of the most important. Data encryption helps keep your data as secure as possible with automatic encryption for sensitive information and email communications.

Your personal information is stored on our servers and heavily guarded – both physically and electronically. And to give your credit card numbers an extra layer of security, we don’t directly connect our firewall-protected servers to the internet.

All of that said: sending sensitive information (like card numbers) via email is never a good idea. If you need to provide this kind of information, a phone call is best.
