The number 915026055 is a landline phone with the Madrid prefix that has generated inquiries among users wanting to know its origin and whether it involves legitimate or unwanted calls. It is a line managed by Telefónica de España, an operator that has been registered as the holder for years.

What is known about 915026055

The number 915026055 corresponds to a landline with the 91 prefix of Madrid. According to available records, the line is registered under Telefónica de España, S.A. Unipersonal, with a registration dating back to 1998. It is a conventional rate number, not a special customer service number like 900 or 902.

Searching for information about this number reveals that in community complaint repositories it is catalogued with a low risk level, although it is important to understand what this means: users who have evaluated the line have assigned it a moderate rating. However, there is no verified information about who operates this number currently or which specific company or entity uses these lines to make calls.

There is a very similar number, 91 502 60 58, which was launched by the Community of Madrid to contact citizens summoned for COVID-19 vaccinations. This number was used by the Personalised Attention Centre (CAP) of the Health Department to confirm vaccination appointments at the region's mass immunisation points. While 915026055 and 91502 60 58 are close numbers, there is no confirmation that they are from the same holder or that they serve the same function currently.

What those who have received calls say

Users who have reported this number on complaint platforms describe incoming calls where it is not always clear who is on the other end of the line. Some affected individuals have commented that they do not identify the reason for the call or that the caller hangs up without establishing clear communication.

In community evaluation records, the number 915026055 appears with a low risk rating, although user opinions are not overwhelmingly abundant. This means that there is no massive pattern of complaints, but there is also no clear consensus on its legitimacy. Some users have marked it as a reliable number, while others cannot confirm its origin.

The relevant point is that several users who have received calls indicate that they cannot identify the actual sender of the calls, which generates distrust even when the line is not linked to verified fraudulent activities.

Is it a legitimate call or spam?

There is no conclusive evidence that 915026055 is a number dedicated to scams or fraud. Complaint repositories classify it with a low to medium risk, but this does not mean that all calls from this number are harmless or that all are spam. The reality is more nuanced.

It is possible that the number is used by different entities or companies to make follow-up calls, appointment confirmations, surveys, or administrative tasks. However, without clear information about who is behind each specific call, it is wise to exercise caution. If you receive a call from 915026055 and do not recognise the reason, you can:

  • Not answer if you are not expecting any pending management
  • Let it go to voicemail to listen to the message
  • Seek confirmation through official channels if the call mentions administrative or health procedures

The important thing is not to confuse lack of clear information with confirmation of fraud. Many legitimate calls from public or private entities may not identify themselves clearly enough, which generates suspicion even if there is no malicious intent.

What to do if you receive a call from this number

If you receive a call from 915026055, the first thing is not to automatically return the call. Although it is a conventional line number and not a special rate number, it is always advisable to verify first.

If the call mentions a specific procedure (medical appointment, vaccination, service confirmation), before accepting personal information or confirming details:

  • Hang up the call safely
  • Contact the supposedly interested entity directly through an official number that you look up yourself
  • Verify that the number matches the official communication channels

Never provide sensitive information such as identity document numbers, banking details, or social security numbers if you are not absolutely sure who is on the other end. Even if the call seems legitimate, it is always safer to hang up and call back from a verified number.

If the call is clearly spam or unwanted, document the date and time, and proceed to block the number on your device.

How to block it and where to report

Block on Android: Open the Phone app, find the number 915026055 in your call history, press and hold the number, and select the option "Block number" or "Add to block list". You can also access call settings and manually create a blacklist.

Block on iPhone: In the Phone app, locate the number in the history, swipe left on the number 915026055 and tap the "Block this contact" icon. You can also search for the number in your contacts list, open it, and choose the block option.

If the calls are unwanted commercial ones, you can request inclusion in the Robinson List, a register managed in Spain where companies can check which numbers do not wish to receive marketing calls. Accessing it is free and significantly reduces this type of contact.

To make a formal complaint about annoying or potentially fraudulent calls, you can contact:

  • The Spanish Agency for Data Protection (AEPD), which manages complaints about privacy and unauthorised commercial calls
  • The Organisation of Consumers and Users (OCU), which receives complaints and provides advice on abusive practices
  • The operator Telefónica, if you have a fixed line contracted with them, can also investigate the origin of unwanted calls

Documenting each call (date, time, content of the conversation if there was one) greatly facilitates the investigation in case you file an official complaint. If you suspect fraudulent activity, it is important to act quickly.
