The Número de Identidad de Extranjero is your permanent foreigner ID number — required for a work contract, a bank account, a rental, a property purchase, taxes, even some phone plans. What it is not: a residence permit or a right to work. That distinction resolves 90% of the confusion around it — the number identifies you, your visa or status authorizes you.
Apply at the Spanish consulate serving your residence: form EX-15, passport, the fee, and a stated economic or social reason (starting a visa process, buying property…). The consulate forwards it to Spain, so the realistic timeline is weeks. If you're arriving on a visa anyway, part of this happens inside that process — ask before filing separately.
The paperwork is easy: EX-15, passport and copy, the tasa 790-012 paid at a bank, proof of your reason. The hard part is the appointment — cita previa slots in Madrid and Barcelona release in waves and evaporate in minutes, while small-province offices book in days. Practical honesty: try at off-hours, check daily, and if your case is urgent, gestorías legitimately queue on your behalf for a modest fee. Once you're in front of someone, the number itself can be same-day.
The Número de Identidad de Extranjero — your foreigner ID number for anything official in Spain: work contracts, opening a bank account, renting, buying property, taxes, utilities. It identifies you; it does NOT by itself give you the right to live or work in Spain. It never expires and never changes.
The NIE is a NUMBER; the TIE is a CARD (Tarjeta de Identidad de Extranjero) that non-EU residents get, which has your NIE printed on it plus your photo and residence status. EU citizens never get a TIE — they get the NIE plus the green residence certificate. If a form asks for your NIE, it wants the number, wherever it came from.
Through the Spanish consulate serving your residence: form EX-15, your passport, the fee, and a stated reason (buying property, opening the visa process, inheritance…). Consulates forward it to Spain, so allow weeks. If you're coming on a visa, note that much of this happens as part of the process anyway — check before making a separate application.
Cita previa (online appointment) at the extranjería office or designated police station for your province, then show up with form EX-15 filled, passport plus copy, the paid tasa 790-012 fee slip, and proof of the economic or social reason. The appointment, not the paperwork, is the bottleneck — slots release in waves and vanish in minutes in Madrid and Barcelona.
The assignment itself can be same-day to a couple of weeks once you're in front of someone; the wait for the appointment is the real timeline, ranging from days in small provinces to weeks-to-months in the big cities. Via a consulate, plan on several weeks end to end. Start early: nothing else in your Spanish admin life proceeds without this number.
No — this is the classic confusion. The NIE identifies you; the right to work comes from your residence/work status: a work permit, the digital nomad visa, EU citizenship. An employer asking for "your NIE" assumes you already have the underlying right to work.
