Schengen Borders Code (Regulation 2016/399)

The Schengen Borders Code (Regulation (EU) 2016/399) codifies the rules governing the crossing of external borders and the operation of internal borders within the Schengen area. It consolidates and replaces the earlier Schengen Borders Code (Regulation (EC) 562/2006), reflecting the evolution of EU border management and the introduction of systematic checks against databases. The Regulation applies to all EU Member States except Ireland and those with opt-outs; associated Schengen States (Norway, Iceland, Switzerland, Liechtenstein) apply the Code under their association agreements.

Scope and Definitions

Article 1 establishes that the Code provides for the absence of border control at internal borders and lays down rules for external border controls. “Internal borders” are defined as the common land borders, airports for intra-Schengen flights, and sea ports for regular ferry connections. “External borders” are land, sea, and air borders with third countries.

Crossing External Borders — Entry Conditions

Article 6 sets out the entry conditions for third-country nationals for stays not exceeding 90 days in any 180-day period. The conditions are cumulative: a valid travel document, a valid visa (if required), justification of the purpose and conditions of stay, sufficient means of subsistence, no alert in the Schengen Information System (SIS), and no threat to public policy, internal security, public health, or international relations.

Entry may be refused even if all documentary conditions are met, under Article 14, where a person is considered a threat. Refusals must be substantiated and communicated via the standard form in Annex V, stating the precise grounds and indicating the right of appeal under national law.

Border Checks — Systematic vs Targeted

The most significant amendment introduced by Regulation 2016/399 concerns systematic checks. Article 8 requires that all persons, including EU citizens and their family members, be subject to systematic checks against relevant databases (SIS, Interpol Stolen and Lost Travel Documents database) when crossing external borders. Previously, only third-country nationals were systematically checked; EU citizens were subject only to a minimum check.

The amendment was a direct response to the terrorist attacks of 2015, following the discovery that several attackers had crossed EU borders undetected. Systematic checks apply at all external border crossing points and may be temporarily relaxed only where specific risk assessment justifies targeted checks.

Temporary Reintroduction of Internal Border Controls

Articles 25 through 30 govern the exceptional reintroduction of internal border controls. This is a measure of last resort, permitted in the event of a serious threat to public policy or internal security. The Code establishes a graduated system:

• Foreseeable events (Article 25): Member States may reintroduce controls for up to 30 days, renewable for up to 6 months, for events such as major sporting events or political summits.
• Immediate threats (Article 28): Where a serious threat requires urgent action, controls may be reintroduced for up to 10 days, renewable for up to 2 months.
• Exceptional circumstances (Article 29): Where the overall functioning of the Schengen area is jeopardised due to persistent serious deficiencies at external borders, the Council may recommend that specific Member States reintroduce controls for up to 6 months, renewable for up to 2 years.

The Code requires Member States to notify the Commission and other Member States, provide a risk assessment, and respect the principle of proportionality. The Commission has issued guidance on the interpretation of these provisions, responding to criticism that internal border controls have become semi-permanent in several Member States since the 2015 migration crisis.

ETIAS — European Travel Information and Authorisation System

The ETIAS Regulation (2018/1240) is closely linked to the Borders Code. Once operational, visa-exempt third-country nationals will be required to obtain a travel authorisation before travelling to the Schengen area. ETIAS will conduct pre-travel security and migration risk assessments, crossing applications against SIS, VIS, Europol data, and Interpol databases. The travel authorisation will be valid for three years.

EES — Entry/Exit System

The Entry/Exit System (EES), established by Regulation 2017/2226, will register the entry and exit of third-country nationals admitted for short stays. The system will record biometric data (fingerprints and facial images) and calculate authorised stay durations automatically. The EES will replace manual stamping of passports and enable systematic identification of overstayers. Its entry into operation, repeatedly delayed, is expected in 2025.

Carrier Responsibility and Penalties

Article 26 of the Schengen Convention, maintained by the Borders Code, requires carriers to ensure that passengers carried to external borders possess the required travel documents. Carriers who bring passengers without proper documentation must return them to the third country and may face penalties under national law implementing the Carrier Sanctions Directive 2001/51.

Judicial Oversight

The Court of Justice has interpreted the Borders Code in numerous cases, including Airport Shuttle Express (Case C-258/21) on the definition of internal borders and NW v Frankfurt Airport (Case C-9/16) on the right of appeal against entry refusals. National courts retain jurisdiction over individual refusals of entry, subject to the uniform standards of the Code.
