NIE in Spain: what it is, NIE vs TIE, and how to get it

What the NIE is

• The NIE is a personal foreigner number for tax, legal and administrative dealings in Spain.
• It is NOT a residence permit and not a work authorisation — only an identifier.
• It is assigned once and stays yours for life (the number itself does not “expire”).
• For non-residents it comes as a certificado de NIE; non-EU residents have it printed on the TIE and EU citizens on their registration certificate.
• An uncommon detail: the Police assign the NIE ex officio when a procedure has begun for a document authorising stay in Spain, or an administrative file has been opened under immigration law. For visas the rule is narrower: automatic assignment applies only where the visa allows more than 90 days in any 180 without a separate long-stay or temporary-residence authorisation. A stand-alone economic, professional or social interest is expressly not automatic; it needs the article 205(4) request.

The NIE “support number” (número de soporte): what it is and where to find it

Online services keep asking for a número de soporte — when you register for Cl@ve, deal with the Agencia Tributaria or verify your identity at a sede electrónica. It is NOT your NIE: it is the serial number of the physical document your NIE is printed on, and it changes every time that document is reissued.

• On a TIE card: top-right corner — the letter E followed by 8 digits. If the printed number has fewer than 8 digits, pad it with leading zeros when typing it in (235566 → E00235566).
• On a card-format EU registration certificate: on the BACK of the card — the letter C plus digits, padded to 8 with leading zeros (C02900966).
• Old green A4 / paper EU certificate: there is no soporte in card format — some online services accept the document differently or not at all; check that service’s help page before a trip to renew.
• A form rejecting your soporte almost always means a format issue: include the letter, pad zeros to 8 digits, no spaces or dashes.
• A new card (renewal, replacement) = a new número de soporte. Update it in any service that stored the old one.

Who needs it

• Anyone with economic, professional or social dealings in Spain.
• For work, opening a bank account, contracts, taxes, buying/renting property, studying.
• EU citizens too (their certificado de registro / green certificate shows the NIE).
• Brazilians and other non-EU nationals — for any formality in Spain.

NIE vs TIE vs NIF

• NIE — the permanent foreigner identifier.
• TIE — the physical card for a non-EU resident; its validity follows the underlying authorisation.
• NIF — the tax identifier; for a foreign individual who has a NIE, the NIF is normally that NIE, while the tax authority can assign a separate NIF where no NIE exists.
• An EU citizen staying over 3 months uses the EU registration procedure and receives a green certificate showing the NIE, not a TIE.
• Número de soporte — the serial number of the physical document, separate from the NIE.
• A NIE by itself does not prove legal stay or residence. Article 206 points to the visa, authorising decision, TIE or another qualifying document for that purpose.

Validity & timing

• The NIE number is permanent — it is not renewed and does not change when a card is replaced.
• New NIE certificates no longer carry an expiry date. An older sheet may still say that it is valid for 3 months, and an institution such as a bank may ask for a recent certificate; that is a document requirement, not expiry of the number.
• For a stand-alone NIE request under article 205(4), and resident/non-resident certificates under article 205(5), the maximum is 5 days from entry of the application in the competent registry; no answer in that period means the request is deemed refused.
• The 5-day clock does not include waiting for an appointment and is not a promise that a consular hand-off or collection will finish in 5 days.

Documents

• Completed Modelo EX-15, with the economic, professional or social reason stated clearly.
• A valid passport or accepted identity document, plus the copies required by the receiving office.
• Proof of payment of tasa Modelo 790 código 012; use the official form for the current concept and amount.
• Evidence matching the stated reason: for example a purchase or arras contract, employer or professional document, bank request, inheritance document or another concrete Spanish transaction.
• For a stand-alone application based on those interests, the law also requires that you are not in Spain irregularly. A NIE application is not a regularisation route.

Getting the NIE in Spain, step by step

1. First check whether a qualifying visa, residence or other immigration file has already caused a NIE to be assigned ex officio; not every visa procedure does.
2. If you need a stand-alone NIE, use the official appointment route for “asignación de NIE” at the competent Extranjería office or police station.
3. Complete EX-15, generate and pay tasa 790-012, and make the supporting document match the reason written in the form.
4. File with the identity documents required by that office and keep the stamped copy or registry receipt.
5. For a stand-alone request, count the statutory 5 days from registry entry, not from booking the appointment or paying the fee.
6. Keep the certificate. If a specific institution later asks for a recent copy, request a new certificate; do not call it a new NIE.

Getting the NIE from abroad: the consulate route

You do not need to travel to Spain. The Spanish consulate serving your place of residence accepts the same EX-15 application and forwards it to the Dirección General de la Policía in Madrid.

• If you are outside Spain, article 205 routes the application through the Spanish consular office for your place of residence to the Comisaría General de Extranjería y Fronteras.
• Use that consulate’s current instructions for appointment, identity copies, proof of residence in the consular district, payment and collection; those logistics are not uniform.
• The same legal conditions apply: state and document the concrete Spanish interest. The formal 5-day period starts only when the request enters the competent registry, so consular transfer and delivery can add time.
• If your real purpose is a long-stay visa or residence, check that route first: the NIE may be assigned inside that procedure instead of through a separate request.

NIE through a representative in Spain (power of attorney)

A representative — a gestor, lawyer or any trusted person with a poder notarial — can apply for your NIE in Spain without you travelling. This is the standard route for non-resident property buyers and heirs.

• Official consular instructions allow representation when it is duly proved, but exact receiving-office requirements vary. Confirm acceptance before granting a power.
• Use a notarised power that expressly authorises the representative to request the NIE; depending on where it was executed and where it will be filed, apostille/legalisation and a sworn translation may be required.
• Prepare the applicant’s identity copy and the representative’s original ID and copies in the form required by that office.
• Representation does not remove the need for a concrete reason or cure irregular stay in Spain.

Lost certificate, “renewing” the NIE, and what can be done online

• There is nothing to “renew”: the NIE number never expires. What can become outdated is the paper certificate.
• Current certificates no longer have an expiry date. If an old one bears the former 3-month wording, or a particular institution asks for recent proof, request a new certificate through the official certificate procedure.
• There is no general official fully-online route issuing a first stand-alone NIE to an individual. Online steps such as the appointment and fee do not replace the filing route.
• A new TIE or EU document gets a new support number, but the NIE remains the same.

A real case: FOGASA called a NIE “expired” — the Supreme Court separated the number from the card

Common mistakes

• Confusing the NIE with the TIE, residence status or the support number.
• Failing to justify the reason for requesting the NIE — a common cause of refusal.
• Booking “NIE assignment” when the real purpose is residence; for example, an EU citizen staying over 3 months uses the EU registration route, which includes assignment of the NIE.
• Showing a NIE certificate issued years ago at a notary or bank that requires one issued within the last 3 months.
• Treating the stand-alone request’s statutory 5 days as appointment time, or counting from fee payment instead of registry entry.
• Assuming that obtaining a NIE regularises an unlawful stay or grants permission to work.

If you are refused

• Get the full written decision and preserve the notification date and filing receipt before deciding whether to reapply or challenge it.
• If the evidence did not match the reason, correct that defect; a generic statement is weaker than a dated document tied to the Spanish transaction.
• For an express refusal, the official Police page lists optional reposición within 1 month or a direct contentious-administrative claim within 2 months.
• Negative silence after 5 days on that stand-alone request is not an express decision. Do not mechanically apply the express-notification deadline without checking the procedural route.
