This error may occur if there is a space before the beginning of a Name in your Ship From address or Ship To address. For example, "Name: PayPal" instead of "Name:PayPal" without a space may cause this error.
To resolve this error:
Remove any extra spaces before the beginning of the Name in your Ship From and Ship To addresses.
Verify that the Name fields in your Ship From and Ship To addresses contain both a First and Last Name. If not, list a full name in the Name field.
Verify that the Company Name field in the Ship From address is filled in. If not, enter in a company name.
Check that there are at least 2 characters in the first and last name for the Recipient. If there is not, update the Recipient name to include both a first and last name, each with at least 2 characters.
If the recipient does include both a first and last name, please contact PayPal support for further assistance.
