NIN - Card or letter? Wrong name?

When you get your NIN, does it come on a card, ala the SSN, or just in letter form, and has anyone had their name screwed up?

You'll get a little red, white, and blue plastic card.  If your name is wrong, you can write to the DWP to have it amended.  (They actually had the incorrect number of some of my stuff....but they fixed it right away.  )

Thanks, and thanks for the quick reply. I thought it would be a card, but I got a letter this morning, and they have me as Mrs Maiden Name instead of Married.

I got a letter telling me to expect my card in a few weeks...then the card arrived.  Perhaps the card is to follow?

I got a card. Name was fine.
