Understanding SIS Alerts and Their Consequences in Germany
An entry in the Schengen Information System (SIS) can have serious consequences for the individual concerned. In Germany, such an alert can lead to the seizure of a motor vehicle, refusal of entry at the border, or even arrest in certain cases.
These alerts are often issued to support police, immigration, and judicial cooperation within the Schengen Area.
When a SIS Alert May Be Unlawful
Although SIS alerts are intended to maintain public security and order, not every alert is legally justified. There are cases where an alert may be issued based on incorrect or outdated information, or in violation of fundamental rights. In such situations, individuals have the right to challenge the alert and seek its deletion.
Deleting a SIS Entry in Germany
If you are affected by a potentially unlawful SIS alert, submitting an application for deletion to the competent German authorities can be a crucial step toward restoring your rights. This process involves requesting access to the data held against you, reviewing the legal basis of the alert, and filing a formal deletion request.
The process can be complex, especially when the alert was issued for serious allegations or under cross-border cooperation. Authorities may take several weeks to respond, and further escalation to German or EU data protection bodies may be necessary if your request is denied or ignored.

What Is the Schengen Information System (SIS)?
The Schengen Information System (SIS) is one of the most important security and border management tools in Europe. It serves as a shared database used to issue alerts on individuals or objects, helping to ensure safety and efficient cooperation between participating countries.
Purpose and Function of SIS
SIS is used for various purposes, including:
-
Identifying and locating individuals wanted for criminal prosecution or extradition,
-
Refusing entry or residence to non-EU nationals who are considered a threat to public order or security,
-
Searching for missing persons, particularly vulnerable individuals such as minors,
-
Seizing property, such as stolen vehicles or forged documents, connected to criminal proceedings.
This system is a cornerstone of police and judicial cooperation across the Schengen Area, enabling authorities to act quickly and effectively across borders.
SIS II: The Second Generation
The second-generation Schengen Information System (SIS II) has been operational since 2013, offering enhanced capabilities and broader access. A total of 30 countries currently participate in SIS II. This includes all EU member states, except Cyprus, as well as the Schengen-associated countries: Iceland, Liechtenstein, Norway, and Switzerland.
Since the United Kingdom left the EU and the Schengen Area following Brexit, it no longer has access to SIS II. This limits its ability to participate in real-time cross-border law enforcement cooperation through the SIS.
Who Has Access to SIS?
Access to the Schengen Information System is strictly regulated. Authorized users include:
-
National police forces and border control agencies,
-
Judicial authorities such as prosecutors and courts,
-
Specific administrative authorities with immigration or security responsibilities.
In addition, EU-level agencies like EUROPOL and EUROJUST have limited access, restricted to data relevant to their operational tasks. Each authority is only permitted to view and process information necessary for fulfilling its specific duties.
National Coordination Through SIRENE Bureaus
Each country participating in SIS II operates a national coordination office, known as the SIRENE Bureau. These offices handle the exchange of supplementary information and coordinate action regarding SIS alerts.
In Germany, the SIRENE Bureau is located within the Federal Criminal Police Office (Bundeskriminalamt, BKA) in Wiesbaden. It plays a key role in managing Germany’s contributions to SIS and ensuring proper communication with other member states.

Who Can Be the Subject of a Schengen Information System (SIS) Alert?
An alert in the Schengen Information System (SIS) is a formal record created to trigger an international search for a person or object. The alert is issued by the country initiating the request, and once entered, it becomes accessible to all other participating Schengen states. This allows national authorities across Europe to take coordinated actions concerning the person or item in question.
Types of SIS Alerts for Individuals and Objects
SIS alerts are commonly issued for several key purposes:
-
To arrest a person based on a valid arrest warrant issued for criminal prosecution or extradition;
-
To refuse entry or residence to third-country nationals who are considered a threat or have violated immigration laws;
-
To locate individuals, such as missing persons, vulnerable individuals, witnesses, or victims involved in judicial proceedings;
-
To seize or confiscate objects, including stolen vehicles, lost passports, or other items relevant to criminal investigations.
What Information Is Stored in SIS Alerts?
When a person is listed in SIS, the alert includes key identification details such as:
-
Full legal name, any known aliases, and gender,
-
Details of the decision that prompted the alert (e.g., arrest warrant, deportation order),
-
Instructions or legal measures to be taken by authorities upon finding the person.
If available, biometric data such as fingerprints and photographs may also be attached to the alert to aid in identification.
Who Can Be Listed in SIS?
SIS alerts can be issued regardless of a person’s nationality. Both nationals of Schengen states and third-country nationals may be subjects of alerts, depending on the circumstances. This ensures that the system functions as an effective cross-border security and law enforcement tool, supporting the mutual cooperation of participating countries.
Whether it concerns a refused visa, a missing person, or a stolen object, SIS serves as a central point of information for authorities across Europe to act quickly and consistently.

Right to Access Personal Data in the Schengen Information System (SIS) – Germany
Individuals have the fundamental right to know whether their personal data is stored in the Schengen Information System (SIS) and to request a review of the legality of such storage. This right is a vital safeguard under European and German data protection law.
Legal Basis for the Right to Information
The right to access SIS data is enshrined in Article 58 of the SIS II Decision (2007/533/JHA) and Article 41 of the SIS II Regulation ((EC) No. 1987/2006). These are further supplemented by Article 57 of the German Federal Data Protection Act (Bundesdatenschutzgesetz, BDSG).
However, this right is not absolute. Authorities may refuse to disclose information if doing so is deemed essential for the performance of lawful duties, such as immigration enforcement or police investigations, or to protect the rights and freedoms of third parties. This restriction is reflected in Article 58(4) SIS II Decision and Article 41(4) SIS II Regulation.
Where to Submit a Request for Information
To find out whether your personal data is stored in the SIS, you may contact the competent national authority in any of the states where the SIS is operational. Since all national SIS databases mirror the central system, it doesn’t matter which country originally issued the alert.
In Germany, the relevant authorities are:
-
The Federal Commissioner for Data Protection and Freedom of Information (BfDI), and
-
The SIRENE Bureau located at the Federal Criminal Police Office (Bundeskriminalamt, BKA).
These authorities process information requests and verify the legitimacy of SIS alerts concerning individuals.
What to Include in Your Application
To request information, you must submit a hand-signed, informal written application. This request should include:
-
Your full name, date of birth, and nationality,
-
A clear and legible copy of your current valid identity document (e.g., passport or national ID),
-
A request for confirmation whether any data concerning you is stored in the SIS.
No formal legal language is required. However, to increase the likelihood of a timely and successful response, your request should be clear, specific, and complete.
Appeals and Legal Remedies
If your application is denied, you have the right to challenge the decision. This can be done through an administrative appeal, and if that fails, you can file a lawsuit before a competent administrative court in Germany.
Additionally, if you receive no response within 60 days, you may initiate an action for information under administrative law to compel a reply.

Deleting a Schengen SIS Alert in Germany: Legal Grounds and Procedures
If your personal data has been unlawfully stored in the Schengen Information System (SIS), you have the legal right to request its deletion. This right is protected under Article 58(5) of the SIS II Decision and Article 41(5) of the SIS II Regulation, which specifically grant individuals the ability to request the erasure of SIS alerts when the processing or storage of that data violates legal standards.
Legal Basis for Deletion Under German Law
In Germany, the Federal Data Protection Act (Bundesdatenschutzgesetz – BDSG), specifically § 58(2), governs the right to erasure. According to this provision, data must be deleted immediately if:
-
The processing of the data is unlawful;
-
The data is no longer necessary for the original purpose for which it was stored;
-
Legal obligations require its deletion.
In this context, “unlawful” means that the storage or processing of the information lacks a valid legal basis. Notably, the decisive factor is not whether the data was originally stored lawfully, but whether it is still lawful at the time of review. Even if the data was lawfully entered in the past, it may still qualify for deletion if circumstances have changed.
Who Is Responsible for Deleting the Alert?
The deletion request must be directed to the authority that originally issued the SIS alert. Only the issuing authority—usually a national immigration or law enforcement body—has the power to remove or correct the alert within the system. Therefore, legal challenges or erasure claims must be addressed to that specific entity.
A successful deletion often requires a legal argument supported by evidence. For instance, if a visa overstay that triggered the alert was later regularized, or if the person’s actions no longer pose a threat to public security, these facts may support a deletion request.
Data Correction as an Alternative to Deletion
If the personal information stored in the SIS is inaccurate, you also have a right to rectification. This means that incorrect or outdated data can be corrected to reflect the current situation more accurately. In such cases, the same legal principles apply, and the request should be addressed to the issuing authority.
Data Processing Restrictions Instead of Deletion
In some situations, deletion may not be granted, especially if erasing the data could negatively affect the rights or interests of others, or public safety. Under § 58(3) BDSG, the competent authority may instead apply a restriction of processing. This means the data will be retained but can no longer be actively used without additional justification.
When deletion is denied or restricted processing is applied, the affected person must be notified in writing, with a clear explanation of the decision and the reasons behind it.
Legal Support for SIS Deletion Requests in Germany
Successfully challenging a SIS alert requires a detailed legal analysis of your situation. An immigration or data protection lawyer can review your case, draft a tailored deletion or correction request, and communicate with the appropriate authorities on your behalf. This is especially important when dealing with entry bans, immigration violations, or erroneous data that may impact your freedom of movement within the Schengen Area.
If you suspect your SIS data was stored unlawfully or no longer has a valid legal basis, consult a lawyer to assess your options and build a strong case for deletion or correction.
