Getting a NIE number (Número de Identidad de Extranjero) is essential if you want to buy property, work, open a bank account, or deal with Spanish authorities.
While the process looks straightforward on paper, many people run into delays, refusals, or costly mistakes.
This guide explains what commonly goes wrong when applying for a NIE, why it happens, and how you can avoid problems.
⸻
1. No Appointments Available (The Most Common Problem)
One of the biggest frustrations is simply getting an appointment.
What goes wrong:
• The online appointment system shows “no appointments available”
• Appointments disappear within seconds
• Wrong province selected
• Users refresh repeatedly and get blocked
Why it happens:
• High demand, especially in coastal areas
• Limited daily appointment slots
• Bots and third-party services reserving slots
• People booking appointments they don’t attend
How to avoid it:
• Check early mornings and late nights
• Use the correct police office for your location
• Be flexible with nearby towns
• Consider professional assistance if time-critical

2. Incorrect or Incomplete Paperwork
Many NIE applications fail because documents are missing or filled out incorrectly.
Common mistakes:
• Incorrect EX-15 form
• Missing copy of passport
• Passport not valid or expiring soon
• No proof of reason for NIE
• Photocopies not provided
Result:
• Appointment wasted
• Told to rebook and return another day
• Delays of weeks or months
How to avoid it:
• Double-check all forms before attending
• Bring originals and photocopies
• Ensure your reason for the NIE is clearly documented

3. No Valid Reason for Requesting a NIE
A NIE is not issued “just in case”.
What goes wrong:
• Applicant says they “might” buy property
• No contract, offer, or legal reason provided
• Purpose not clearly explained on EX-15
Result:
• Application rejected
• Told to return when there is a real need
Accepted reasons include:
• Property purchase or sale
• Employment
• Self-employment
• Inheritance
• Banking or tax obligations
⸻
4. Language Barriers at the Appointment
Most police stations operate entirely in Spanish.
What goes wrong:
• Applicant cannot understand instructions
• Incorrect answers given to questions
• Stress and confusion during the appointment
Result:
• Incorrect submission
• Missed steps
• Application refusal
How to avoid it:
• Bring a Spanish speaker
• Prepare answers in advance
• Use a professional service familiar with local offices
⸻
5. Paying the Wrong Fee (Or Not Paying at All)
The NIE fee (Modelo 790, code 012) must be paid before the appointment.
Common issues:
• Wrong form downloaded
• Incorrect fee amount selected
• Fee not paid at bank
• Receipt not brought to appointment
Result:
• Appointment cancelled
• Asked to return another day
⸻
6. Applying in the Wrong Location
NIE applications must usually be made:
• In the province where the reason applies
• Or at a Spanish consulate abroad
What goes wrong:
• Booking in a different province
• Using an address that doesn’t match documentation
• Attending the wrong police station
Result:
• Turned away at the desk
⸻
7. Using Unreliable Online Services
Not all online NIE services are equal.
Risks include:
• No real appointment booked
• Fake confirmations
• Overcharging
• No follow-up support
• Poor communication
How to protect yourself:
• Check reviews and business details
• Avoid “guaranteed appointment” claims
• Use transparent, Spain-based services
⸻
8. Delays That Impact Property Purchases or Jobs
A delayed NIE can cause serious financial consequences.
Possible outcomes:
• Property sale falls through
• Mortgage delayed
• Job offer postponed
• Legal deadlines missed
⸻
9. Confusing NIE With Residency
A very common misunderstanding.
Important:
• NIE ≠ residency
• A NIE does not grant the right to live or work in Spain
• Separate residency or visa processes may apply
Failing to understand this can cause immigration issues later.
⸻
10. Not Keeping Proof of Your NIE
Sometimes the NIE is issued on a simple A4 certificate.
What goes wrong:
• Document lost
• No digital copy saved
• NIE number forgotten
Tip:
• Scan and store copies securely
• Keep the number recorded separately
⸻
Final Thoughts: Avoiding NIE Problems
Most NIE problems are completely avoidable with:
• Correct paperwork
• A valid reason
• The right appointment
• Clear understanding of the process
If your situation is time-sensitive or complex, professional guidance can save weeks of stress.
