Getting verified

If you're not a "verified user" then there are restriction imposed

  • US$500/month sending
  • Can't accept credit cards on your site

The only way to get verified is to add a credit card to your account.

Loaded Card

NZPost do Prezzy Cards and Loaded Cards which work like a normal VISA credit card, but are pre-paid. The Prezzy cards are anonymous, but the Loaded Cards are registered to a particular person and require ID to aquire (but there are no credit restrictions), so they should be able to be used for account verification for PayPal users who with bad credit ratings.

  • According to this comment Loaded cards are accepted by PayPal
