The card arrived in the mail today (pleasantly sooner than expected). Called up and activated it without issue. Am I right in assuming that Citibank send the card's PIN separately in the mail? I went to register for Citibank Online but realise that I don't have a PIN yet. Guess I'll have to wait until next week for that.
Yes, that's correct. In my experience it'll normally arrive 2-3 business days after the card.
