How to obtain an N.I.E. number in Spain? – Data 2025

What is an N.I.E. number?

There is a widespread belief that Spanish bureaucracy can be a headache. However, the system is surprisingly well organised – once you get to know it. The NIE (Número de Identidad de Extranjero) number is the foundation of every foreigner’s existence in the Spanish administrative system. It is a unique, personal and exclusive identifier, without which it is practically impossible to function in the local legal and economic reality.

For Poles and other foreigners planning any interaction with Spanish institutions, obtaining a NIE number is not a choice but a necessity. It is a key that opens the door to the Spanish property market, employment, banking system and business activities.

In this article, we will guide you step by step through the process of obtaining a NIE, explain who needs it and why, what the application procedure looks like in both Spain and Poland, and what benefits and obligations are associated with having this number.

Final tips for those applying for a NIE number

1. Plan ahead – the process may take longer than you expect, especially in popular regions.
2. Prepare all documents thoroughly – incomplete documentation will guarantee rejection of your application.
3. Consider professional assistance – if you do not speak Spanish or your situation is complicated.
4. Keep copies of all documents – including the application form and payment confirmation.
5. Be patient and persistent – Spanish bureaucracy requires patience, but with good preparation, the process will run smoothly.

Basic information about the NIE number

Who needs a NIE number?

The NIE number is essential for a wide range of foreigners, including:

• People planning to purchase property in Spain – even if you do not intend to live there permanently, the mere purchase of a holiday apartment requires you to have a NIE
• Foreigners taking up employment in Spain – both temporary and permanent
• Entrepreneurs setting up a company or conducting business activity in Spain
• Long-term students coming to study at Spanish universities
• Long-term residents planning to settle in Spain
• Anyone who has any economic, professional or social interests related to Spain

Spanish law is clear on this matter – without a NIE number, you will not be able to carry out virtually any formal transaction in Spain. This is an absolutely fundamental requirement, even if your interactions with the Spanish system are sporadic.

How does the NIE differ from other identification documents?

The Spanish identification system may seem complicated at first. Here are the main differences between the key documents:

Document	Purpose	For whom
National Identity Card (DNI)	Basic proof of identity	Only for Spanish citizens
NIE (Foreign National Identity Number)	Foreign national identification number	For foreigners residing or doing business in Spain
Tax Identification Number (TIN)	Tax identification number	For natural and legal persons; for Spanish citizens, it coincides with the DNI, and for foreigners, with the NIE.
VAT number (Tax Identification Number)	Former tax identification code for companies	Currently replaced by NIF (name used until 2008)

It is important to understand that the NIE is not just a physical document, but above all an identification number that remains with you for life, regardless of changes in your immigration status.

Is the number permanent or temporary?

There are two types of NIE numbers depending on the nature of your stay:

• NOT temporary – granted to foreigners staying in Spain for a limited period, such as students or seasonal workers
• NOT permanent – for people obtaining permanent residence in Spain

However, it should be emphasised that the NIE number itself is NOT permanent and is assigned once for life. Even if you change your migration status or citizenship, your NIE number will remain the same. What may change is the document confirming your NIE number or the residence card (TIE) containing this number.

The process of obtaining a NIE number

Where can I obtain a NIE number?

There are several institutions where you can apply for a NIE number:

In Spain:

• General Police Directorate
• Immigration Offices
• Police Stations

Outside Spain:

• Spanish diplomatic missions or consulates in the applicant’s country of residence

The choice of the appropriate institution depends on your location and residence status. If you are already in Spain, the best solution is to go to your local immigration office or police station. If you are applying from Poland, you must contact the Spanish consulate.

Is it possible to obtain a NIE number in Poland?

Yes, Polish citizens can apply for a NIE at the Spanish consulate in Warsaw. The procedure requires:

1. Make an appointment (cita previa) by calling 22 583 40 00 or sending an email to sc.varsovia@maec.es
2. Appearing in person at the consulate with the required documentation
3. Providing documentation of your place of residence in Poland
4. Demonstrating a justified need to obtain a NIE not related to interests in Spain

The Spanish Consulate in Warsaw usually issues a NIE within two weeks of submitting the application, but this time may be extended due to various circumstances.

However, there are certain restrictions when applying from abroad. The consulate may require a more detailed justification for the need to obtain a NIE, especially in the case of plans to purchase property or take up employment. In addition, waiting times for an appointment may be longer than when applying directly in Spain.

What documents are required?

Preparing the right documentation is key to the efficient process of obtaining an NIE. You will need:

• EX-15 application form – completed and signed by the applicant or their representative (the economic, professional or social reasons justifying the need for an NIE must be clearly stated)
• Identity document – original and copy of a valid passport (for non-EU citizens) or identity card (for EU citizens)
• Justification – documents confirming the need to obtain a NIE (e.g. property purchase agreement, employment contract, documents confirming the commencement of business activity)
• Confirmation of payment – proof of payment of the administrative fee (Tasa 790 Código 012)
• Additional documents for special cases – e.g. for minors, a copy of the birth certificate or guardianship document is required

All documents drawn up in a language other than Spanish must be translated by a sworn translator. Errors in documentation are the most common reason for rejecting an application, so it is worth taking the time to prepare them carefully.

Practical aspects of the process

Do I need to book an appointment (cita previa)?

Yes, the process of applying for a NIE requires you to book an appointment (cita previa) in advance at the relevant office. This is a mandatory part of the procedure, which is often challenging due to the limited availability of appointments.

Appointments can be made:

• By telephone – by calling the selected office
• Online – via the official website of the Spanish administration (https://sede.administracionespublicas.gob.es)
• In person – in some offices, it is possible to book an appointment on site

Due to high demand, it is advisable to try to get an appointment as early as possible. Waiting times can vary significantly depending on the region – in large cities such as Madrid or Barcelona, the waiting time can be as long as 3-5 months, while in smaller towns it is possible to get an appointment within a few weeks.

How much does it cost to obtain a NIE number?

Obtaining a NIE involves the following costs:

Official administrative fees:

• The standard administrative fee (Tasa 790-012) is EUR 9.84 for the first application.
• The cost of updating the NIE is EUR 7.13.
• The fee must be paid before submitting the application, and proof of payment must be included with the documentation.

Additional costs:

• Certified translations of documents – e.g. a certified translation of a NIE from Spanish into another language costs around EUR 22
• Intermediary services – the cost of hiring an intermediary to help obtain a NIE ranges from EUR 250 to EUR 350
• Travel and accommodation – if a personal visit to Spain is necessary, these costs can significantly increase the total expense

It is worth remembering that although the administrative fee itself is relatively low, the actual cost of obtaining an NIE may be significantly higher due to additional expenses, especially if you are applying from abroad.

How long does the entire process take?

The time required to obtain an NIE varies depending on where the application is submitted:

• The standard waiting time is approximately two weeks from the date of submitting a complete application.
• In some cases, it is NOT possible to obtain it on the same day, even if all documents are correctly prepared and the office is not overloaded.
• At foreign consulates, the waiting time may be longer, up to a month.

However, the key factor affecting the length of the process is the waiting time for an appointment (cita previa), which, as mentioned earlier, can be as long as several months in popular regions.

The possibilities for speeding up the process are limited, but there are some options:

• Use the services of professional intermediaries who may have access to faster deadlines
• Apply in less popular locations where waiting times are shorter
• In urgent cases related to business activities, it is possible to apply for an expedited procedure

Assistance in obtaining a NIE number

Do I need help obtaining a number?

Although it is theoretically possible to obtain a NIE on your own, in practice many people decide to seek professional assistance. Consider such support if:

• You do not speak Spanish – the language barrier can be a significant obstacle, as all forms and procedures are in Spanish
• Your situation is complicated – if your case requires additional documentation or special procedures
• You have limited time – if you need your NIE quickly and cannot wait for the standard procedure
• You do not live in Spain – organising the entire process from abroad can be difficult

When is it worth using the services of a solicitor/manager?

The Spanish administrative system employs specialists known as “gestores administrativos”, who specialise in handling official matters. A gestor is something between a Polish legal advisor and an administrative advisor – a professional who understands the intricacies of Spanish bureaucracy.

Using the services of a manager or solicitor is particularly advisable in the following cases:

• Purchase of real estate requiring quick NIE acquisition
• Complex cases related to business activity
• When you have difficulty obtaining an appointment (cita previa)
• When you are outside Spain and cannot appear in person at the office

Approximate costs of professional assistance

Using the services of intermediaries involves additional costs:

• Typical fees for full service in obtaining an NIE range from EUR 250 to EUR 350.
• Some companies offer lower rates, e.g. around EUR 270.
• A notarised power of attorney, if required, may cost an additional EUR 50-100.

It is worth comparing the offers of different service providers, as the scope of services provided may vary. Some companies offer only basic assistance in completing forms, while others provide comprehensive services, including representing the applicant at the office.

Is it necessary to know Spanish?

Formally, knowledge of Spanish is not required, but in practice, the lack of this skill significantly hinders the independent completion of the procedure. All forms, instructions and communication in offices are conducted in Spanish.

If you do not know Spanish, you have several options:

• Use the services of an interpreter when visiting the office
• Hire an agent or manager to guide you through the process
• Ask a Spanish-speaking friend for assistance

The situation is somewhat easier at Spanish consulates abroad, as some staff members can communicate in English, but all forms will still be in Spanish.

The most common problems and how to avoid them

The most common mistakes when applying for a NIE number are:

• Incomplete documentation – failure to submit any of the required documents will result in the application being rejected
• Incorrectly completed EX-15 form – errors in the form are a common reason for rejection
• Lack of justification – insufficient documentation of the need to obtain an NIE
• Insufficient preparation for the visit – unfamiliarity with the procedure and requirements
• Problems with booking an appointment – attempts to obtain a cita previa too late

To avoid these problems, it is recommended that:

• Carefully review the documentation requirements.
• Prepare all documents in advance, including translations.
• Start the appointment booking process early.
• If in doubt, consult a professional.

Practical application of the NIE number

What can I do with my NIE number?

It is NOT necessary for carrying out various administrative and economic activities in Spain:

• Purchasing property – without a NIE, you cannot purchase any property in Spain, not even a holiday apartment.
• Opening a bank account – most Spanish banks require a NIE to open an account.
• Signing an employment contract – you cannot obtain legal employment without a NIE.
• Starting a business or company – a NIE is essential for registering a business.
• Paying taxes – the NIE number serves as a tax identification number
• Purchasing a vehicle – registering a car or motorbike requires a NIE
• Connecting utilities – contracts for electricity, water or internet supply
• Access to social benefits – for long-term residents

It is NOT the basis for formal existence in the Spanish system – without it, you are practically invisible to the Spanish administration.

What can’t I do without a NIE number?

Without a NIE number, it is not possible to:

• Formal participation in the Spanish economic and administrative system
• Signing most contracts with Spanish entities, both public and private
• Legal purchase of property in Spain – a notary will not carry out the transaction without a NIE
• Obtaining a work permit – legal employment
• Tax settlement – even if you are required to pay taxes in Spain

The consequences of not obtaining a NIE number in Spain can be serious:

• Inability to formalise transactions and contracts
• Inability to open a bank account
• Problems with legalising stays longer than 3 months
• Exposure to penalties for non-payment of taxes
• Loss of potential business or investment opportunities

Does it replace a residence permit?

A NIE is not the same as a residence card (Tarjeta de Identidad de Extranjero – TIE):

• The NIE is the identification number itself, while the TIE is the physical residence card containing this number.
• After receiving a residence permit, a foreigner has one month to apply for a TIE card.
• The TIE card needs to be renewed (usually every 2 years), while the NIE number itself remains unchanged
• Having a NIE does not automatically give you the right to stay in Spain for more than 3 months

For those planning a longer stay in Spain (more than 90 days), simply having a NIE is not sufficient – it is also necessary to obtain the appropriate residence permit.

Important additional questions

What should you do if you lose a document containing your NIE number?

If you lose your NIE certificate:

1. Apply for a duplicate at the same institution that issued the original document.
2. Fill in form EX-15, selecting the “Duplicate” option.
3. Attach your identity document and proof of payment for the duplicate (EUR 7.13).
4. In the event of theft, it is also advisable to report it to the police.

Please note that the number itself does NOT change – only a new document confirming its ownership is issued.

Does every family member need their own NIE number?

Yes, every foreigner, regardless of age, needs their own NIE:

• Children and other dependents must also have an individual NIE number.
• In the case of minors or incapacitated persons, the application is submitted by their parents or legal guardians.
• There is no such thing as a “family NIE” — each person must have their own unique number.

This even applies to infants and young children if they are to be included, for example, in the purchase of real estate or in other official documents.

Does the number expire?

The number itself is NOT permanent and does not expire:

• It is NOT granted for life and does not change even after a change in migration status or citizenship.
• The document confirming the NIE (the so-called “NIE blanco”) may have a limited validity, usually 3 months.
• Residence cards (TIE) containing the NIE number must be renewed in accordance with the conditions of the residence permit. (usually every 2 years).

It is worth remembering that although the number itself remains unchanged, the documents confirming it may need to be renewed or updated.

The relationship between NIE and NIF (Tax Identification Number)

For foreigners, it does NOT serve as a NIF (Número de Identificación Fiscal) – tax identification number:

• The NIF is used for tax and financial purposes.
• For Spanish citizens, the NIF is the same as the DNI number.
• For foreigners, the NIF is the same as the NIE number.
• In practice, this means that if you have a NIE, you automatically have a NIF as well.

This dual function is NOT particularly relevant for individuals who run a business or own property in Spain, as it enables them to fulfil their tax obligations.

NIE number and tax resident status

Simply having a NIE does not automatically make you a tax resident in Spain. Tax residency status depends on other factors:

• Staying in Spain for more than 183 days in a calendar year
  Having your main centre of economic interests in Spain
  Having a spouse and/or children who are tax residents of Spain

Tax residency issues are complex and can have a significant impact on your tax liabilities in both Spain and Poland. If in doubt, it is advisable to consult a tax advisor specialising in international tax law.

Regional differences in the process of obtaining

Are there differences in the procedure for obtaining a NIE number in different regions of Spain? Yes, the process may vary slightly depending on the region:

• Catalonia and the Balearic Islands – usually longer queues and more difficult to get an appointment, especially during the summer season
• Andalusia – a slightly more flexible approach, often possible to obtain a NIE on the same day
• Madrid – a very formalised process, but with a well-organised online system
• Canary Islands – relatively efficient process, but may be difficult during the peak tourist season

Local authorities may also differ in their interpretation of certain requirements, e.g. regarding the type of acceptable documentation justifying the need to obtain a NIE. It is worth checking the specific requirements in the region where you plan to submit your application in advance.
