We need your help resolving an issue with your account. To give us time to
work together on this, we've temporarily limited what you can do with your
account until the issue is resolved.
We understand it may be frustrating not to have full access to your PayPal
account. We want to work with you to get your account back to normal as
quickly as possible.
What's the problem?
By law, once you reach a certain amount which you've sent and/or withdrawal
from your PayPal account, we'll need to ask you to confirm your identity.
This procedure is similar to the requirements that must be met when opening
a bank account or applying for a credit card account, and is also known as
"Know Your Customer" or KYC.
Please help us confirm your identity by providing some documentation and
updating your PayPal account profile with your current address. Or, go to
the Resolution Centre to find out more.
