The number 915026055 is a fixed phone located in Madrid that has generated inquiries among users who wish to identify who is behind the calls they receive. If you have seen this number on your screen or have doubts about whether it is safe to return the call, here you will find the available information and the steps to follow.

What is known about 915026055

The number 915026055 is a fixed line with the prefix 91, corresponding to the province of Madrid. According to the available technical records, the line is operated by Telefónica de España, S.A., the main telecommunications operator in the country.

In specialized telephone directories, this number is listed as a reliable number with a low risk rating in communities of users who value the security of phone calls. However, there is no verified information about who specifically operates this number at present, nor about the entity responsible for making calls from it.

What is known is that during the COVID-19 vaccination campaign in the Community of Madrid, official contact numbers were set up to confirm vaccination appointments. The similar number 91 502 60 58 was used by the Personalised Attention Centre (CAP) of the Madrid Health Department to contact citizens summoned to mass vaccination points and public hospitals in the region. The 915026055, although very similar, differs in the last digit.

What those who have received calls say

On user platforms where suspicious phone numbers are reported, 915026055 does not appear with a significant volume of complaints. The existing risk ratings are low, suggesting that it is not a number associated with mass scams or phone fraud.

However, some users report having received calls from it without clear context about who was calling. Since it is a Madrid number operated by Telefónica, it is possible that these are commercial calls, administrative management, public agency calls, or companies with offices in Madrid. The lack of centralized information about its specific owner leads many people to question whether it is safe to answer.

Is it a legitimate call or spam?

There is no verified information indicating that 915026055 is a number dedicated to scams or fraudulent activities. The available risk assessment in user communities is low, which contrasts with numbers clearly identified as spam or fraud.

That said, the similarity to the official vaccination number of Madrid (91 502 60 58) could cause confusion. If you receive a call from 915026055 and do not expect contact from any specific institution or company, it is wise not to provide personal, banking, or identity document information without first confirming the legitimacy of the call.

One way to verify if it is legitimate is to not return the call immediately. If you believe it is from a known entity, hang up and call the official number of the organization or company you suspect has contacted you. This way, you avoid falling victim to a possible identity theft.

What to do if you receive a call from this number

If you receive a call from 915026055 and do not recognize who it is, the first thing is to remain calm and not provide sensitive information. Here are the recommended steps:

  • Do not return the call immediately. If it is important, the person or entity calling will try again, preferably with a clear message about who they are.
  • Request identification. If you manage to speak with someone, ask them to fully identify themselves: name of the company, department, reason for the call, and a reference number.
  • Verify independently. Look up the official phone number of the organization or company that claims to have called you and contact them directly to confirm that they made the call.
  • Do not share personal data. Never provide your bank account number, passwords, credit card number, or identity document information over the phone, even if they claim to be an official entity.
  • Document the call. Note the time, date, and any details you remember about the conversation. This will be useful if you need to report it.

How to block it and where to report
