How To Get NIE Spain
DO NOT PAY ANYONE TO DEAL WITH IMMIGRATION IN SPAIN EVER
A NIE is a Spanish Tax Number for foreiners. If you intend to move to Spain, purchase a car or property you will need one. A lot of unscrupulous people charge extortionate amounts to get one for you. I have heard of people being charged over €500 which is disgraceful.
It is possible to get one before you move to Spain or after you arrive in Spain.
How to get one before you move to Spain
Contact your nearest Spanish Consulate by email and request an appointment. Before they give you an appointment they will ask.why you want it. You need to State that you intend to purchase a property. Do not tell them that you need it to move to Spain. You then will need to attend an appointment and fill out à form and pay a small fee of around €10. Your NIE Certificate will then be emailed to you.
