Gift card codes are like cash.
We strongly recommend that you apply the same level of security precautions for your eGift Card as you do to protect your physical wallet, cash and credit cards.
Protect yourself from Unauthorized Use.
Unauthorized use can occur from someone you know -- or someone you don't.
If you opt to print your eGift Card, please guard it closely at all times.
Your account and password credentials should be safeguarded and protected at all times. If you use a shared computer, extra precautions should be taken.
Perform a balance check on a gift card you purchased.
If you have any question about a remaining balance, you can perform a search on "[BRAND] Balance Check" to determine the remaining value.
Beware of Known Scams: Internet and Otherwise
This page, published on the AmazonPay website is extremely informative and useful in understanding known scams so you can avoid them:
If you suspect unauthorized use, take action now.
If you suspect that someone accessed your personal information without your consent or knowledge -- and used it to create an account or purchase a gift card, immediately report it to your financial institution and the authorities.
Changing passwords to your eCommerce accounts and apps is also highly recommended.
