You take the RER every morning, you validate your Navigo pass, and the journey works. Until the day you realize that your plan covers zones you never cross, or worse, that it doesn’t cover enough. The Navigo zoning in Île-de-France is based on a division into five concentric circles around Paris, and understanding this map directly affects what you pay each month.
Fare Reform 2025: Zoning No Longer Applies to All Transport Tickets
Before diving into the zone map, a recent technical point deserves your attention. Since the fare reform that came into effect in 2025, a single ticket no longer depends on the zones crossed. Whether you travel two metro stations in Paris or take a full RER to zone 5, the price of a single journey remains the same across the entire region.

This reform has a direct consequence: zoning 1 to 5 is only crucial for Navigo passes (Weekly, Monthly, Annual). If you travel occasionally, the zone calculation no longer applies to you with a single ticket. However, if you are a subscriber, choosing the right zones on your pass remains the main lever to adjust your transport budget.
To accurately visualize which municipalities belong to which zone, the Navigo zone map 1 to 5 allows you to locate your station and that of your workplace before subscribing to a pass.

Navigo Pass Zones 1-5: 2026 Rate and Calculation Logic
Since January 1, 2026, the Navigo Monthly all zones 1-5 costs 90.80 euros per month, compared to 88.80 euros the previous year. This 2.3% increase applies to all Île-de-France tickets, both subscriptions and reduced fares.
Why this single price for five zones? The Navigo all zones provides access to the entire network: metro, RER, Transilien, buses, and Noctilien across all of Île-de-France. It’s the simplest option, but not always the most economical.
Partial Pass or All Zones: The Real Calculation to Make
If your daily trips remain between zones 1 and 3 (Paris and its immediate suburbs), a pass limited to these zones costs less than an all zones pass. The classic trap is to subscribe to a 1-5 pass by default, without checking whether your arrival station is actually in zone 4 or 5.
Conversely, underestimating your zones exposes you to checks and fines. A journey outside the zones covered by your pass is considered a trip without a valid ticket. The monthly savings do not compensate for the risk.
- Identify the exact zone of your departure and arrival stations on the official map before any subscription
- Count your occasional trips outside the zone: if you exceed your pass less than twice a week, single tickets in addition are cheaper than upgrading to a higher pass
- Holders of the Navigo Annual benefit from de-zoning during the summer (until August 15), allowing travel across all zones without extra cost during this period
Limits Between Navigo Zones: Problematic Cases
The zoning follows a logic of distance from Paris, not a network logic. Two stations just a few hundred meters apart can belong to different zones. This is the case in several areas of the Greater Crown, where the boundary between zone 4 and zone 5 crosses neighboring municipalities.
Your transfer station is as important as your arrival station. If you change trains at a station located in zone 4, your pass must cover this zone, even if your journey starts and ends in zone 3. This point is often unknown to users who take RER or Transilien lines with transfers in the suburbs.
Noctilien and Night Buses: A Network That Sometimes Ignores Zoning
The Noctilien network (night buses) covers Île-de-France with its own lines, and the zone coverage of your pass normally applies here. However, some Noctilien routes cross zones that you never travel through during the day. Check the night network map if you use it regularly: a Noctilien journey can take you out of your zones without you realizing it.
Changing Zones on Your Navigo Annual Pass
Have you moved or changed jobs? The Navigo Annual pass allows you to modify the covered zones, but not at any time. The request to change zones is made to Île-de-France Mobilités, and the new zoning takes effect the month following validation.
Two common mistakes slow down this process:
- Making the request too late in the current month, which delays the application to the following month
- Forgetting that the employer reimbursement of 50% applies to the actual amount of your subscription, including zones. Adjusting your zones also changes the amount reimbursed by your employer
- Not checking that the new zone covers all transfer stations of the journey, not just the departure and arrival stations
Employer reimbursement remains an underutilized lever. Every employee in Île-de-France is entitled to it, regardless of their contract type, and the coverage is for half of the monthly or annual pass. Adjusting your zones accurately optimizes both your net expenditure and the reimbursed amount.
The Navigo zoning remains a readable system as long as it is checked once, with the correct map, at the time of subscribing or renewing. Since the 2025 reform, occasional travelers no longer have to worry about it. For subscribers, the difference between a well-calibrated pass and a default pass represents several dozen euros per year.
