Schengen compliance glossary
Plain-English definitions of the terms that come up when monitoring employee travel against the 90/180-day rule.
Schengen Area
A border-free travel area made up of 29 European countries: 25 EU member states and four non-EU countries.
The Schengen Area is not the same as the European Union. Its formal membership determines which ordinary short-stay presence days draw from the shared 90-day allowance.
Andorra, Monaco, San Marino and Vatican City are not Schengen members. ComplyEur treats Andorra as outside the area, although travel through France or Spain still creates Schengen presence days. It temporarily applies a conservative operational assumption to Monaco, San Marino and Vatican City and flags affected records for manual review.
Ireland and Cyprus are EU members that are not in the Schengen Area. Days spent there do not count towards the 90-day allowance. Norway, Iceland, Liechtenstein and Switzerland are in Schengen without being in the EU, and days there do count.
90/180-day rule
In-scope short-stay travellers may spend at most 90 days inside the Schengen Area in any rolling 180-day period.
The rule applies to short stays for tourism or business. Since Brexit it applies to UK citizens, who were previously exempt as EU nationals.
Long-stay visas, residence permits, protected family-member rights and bilateral arrangements can change an individual traveller’s position. A general 90/180 calculation does not determine whether a planned business activity requires separate work authorisation.
The limit is 90 days of physical presence, not 90 days per trip and not 90 days per country. Days spent in France, Germany and Spain all draw down the same single allowance.
Rolling 180-day window
The 180-day period is measured backwards from any given day, not from a fixed start date. It moves every day.
This is the part people most often get wrong. The window is not a calendar period that resets on 1 January or on the anniversary of your first trip. To check any date, count back 180 days from it and total the days you were present in that span.
Without new travel, old presence days eventually drop out of the back of the window, so the position stays the same or improves. A future planned trip can still cross the limit, which is why the calculation must be checked against the proposed travel dates.
Days used
The number of days of physical presence inside the Schengen Area within the current 180-day window.
Both the day of entry and the day of exit count as full days, regardless of the time you crossed the border. Arriving at 23:50 on Monday and leaving at 00:10 on Wednesday uses three days.
A single calendar day never counts twice, even if you visit two Schengen countries on it. If travel records overlap — a common artefact of importing from several sources — the day is counted once.
Days remaining
The 90-day limit minus days used. A negative figure means the limit has been exceeded.
Days remaining is only meaningful relative to a specific date, because the window moves. "42 days remaining" always means "42 days remaining as at this date".
ComplyEur’s default bands use days already spent: green is 0–68, amber is 69–82, red is 83–90, and breach begins at 91. Company settings can use different warning thresholds.
Overstay
Remaining in the Schengen Area beyond the 90 days permitted in the rolling 180-day window.
Consequences vary by member state and by the length of the overstay. They can include fines, a recorded entry ban, and complications for later visa or travel authorisation applications.
An overstay is assessed against the traveller, not the employer, but the disruption lands on the business: an employee barred from the Schengen Area cannot attend the site visit, the client meeting, or the project they were assigned to.
Entry ban
A formal prohibition on re-entry imposed by an authority for a set period; its territorial effect depends on the decision and applicable law.
Entry-ban decisions and their duration depend on the issuing authority, circumstances, and applicable law. A related SIS refusal alert can have consequences beyond the issuing country, but the territorial effect should be checked for the individual decision.
A ban recorded electronically is materially harder to work around than a missed passport stamp was, because it is attached to a biometric record rather than to a physical document.
EES (Entry/Exit System)
The EU border system, fully operational since 10 April 2026, that records external-border crossings for short-stay non-EU travellers within its scope.
For travellers within scope, EES uses travel-document data and biometrics to record crossings at the external borders of participating European countries. It supports authorities in checking authorised short stays without relying only on passport stamps.
The official remaining-stay information may not reflect time spent in the Schengen Area before 10 April 2026, so employers and travellers still need a complete travel history when reviewing the rolling allowance.
ComplyEur does not connect to EES. It calculates from the trip information supplied by the employer and traveller, so incomplete or inaccurate records can produce an incorrect result.
ETIAS
A planned pre-travel authorisation for visa-exempt visitors that the EU says will start operating in the last quarter of 2026.
ETIAS is not operating yet and applications are not currently being collected. Once it launches, it will be an authorisation to travel rather than a visa or residence permit.
ETIAS is separate from the 90/180 rule and will not change it: holding a valid authorisation will not grant additional days or exempt anyone from the limit.
The two are frequently confused. ETIAS governs whether you may set off; the 90/180 rule governs how long you may stay once you arrive.
Type D (long-stay) visa
A national long-stay visa issued by a single Schengen state, which changes how time in that country is counted.
Days spent in the issuing country under a valid Type D visa or residence permit are generally not counted against the 90-day short-stay allowance, because the person is not present as a short-stay visitor.
This makes the arithmetic materially more complex, and a general short-stay calculation — including ComplyEur’s standard calculation — may not reflect the person’s position. If your travellers hold long-stay visas or residence permits, use a process built for immigration casework and take professional advice.
Earliest safe entry date
The first future date on which enough days have aged out of the rolling window to allow entry again.
When someone has exhausted their allowance, the position recovers automatically as old days pass out of the back of the 180-day window. The earliest safe entry date is the first day on which re-entry no longer breaches the limit.
It is a planning figure rather than a guarantee: it assumes the recorded travel history is complete and that no further trips are added in the meantime.
These definitions explain how the rules are applied in practice. They are not legal or immigration advice. Where a decision turns on interpretation rather than counting, take professional advice.
