Who needs it

EU, EEA and Swiss nationals planning to stay more than three months must register and receive this certificate. Non-EU nationals do not get this — they receive a TIE card instead (see is the NIE a card? NIE vs TIE).

What it contains

  • Green paper document (not a plastic card).
  • Your name, NIE, address, nationality and date of registration.

Green NIE vs white NIE

  • Green = EU citizen, resident (registered > 3 months), form EX-18.
  • White = non-resident NIE certificate — see the white NIE.

Both contain the same kind of NIE number; the colour reflects your status, not a different number.
