The 3900 is the unique number set up by Orange to centralize requests from its customers and those wishing to subscribe to an offer. This Crystal number, not premium-rate, works from any landline or mobile phone in mainland France. Advisors can be reached from Monday to Saturday, from 8 AM to 8 PM. Outside of these hours, a voice server remains active for certain automated operations.
Voice server of 3900: navigation and automatic identification
As soon as you dial 3900, an interactive voice server takes over the call. It asks you to enter the ten digits of the relevant line number. This step allows the system to identify the account and direct you to the right contact.
Three main options are offered after identification:
- Press 1 in case of loss or theft of the phone, to immediately initiate the suspension of the line
- Press 2 for any questions related to an offer, a subscription, or a contractual modification
- Press 3 for a request related to an internet offer (Livebox, fiber, fixed connection)
Customers calling from an Orange mobile can also dial 700. The line is then automatically recognized, allowing you to skip the identification step and reduce the time spent in voice menus.
To better understand the specific cases in which this number provides a quick response, a detailed guide on the hours of 3900 Orange distinguishes commercial requests from technical requests.
Calling Orange customer service from abroad: number and billing
The 3900 does not work outside of mainland France. Dialing this short number from a foreign network does not initiate any connection. Orange has provided a substitute number: +33 9 69 39 39 00.
This long number follows the same hours as the 3900 (Monday to Saturday, 8 AM to 8 PM). It is not charged extra by Orange. However, the call is billed by the local operator according to its own rates for a call to France.
Particular case of roaming in the European Union
The European regulation known as “Roam Like at Home” aligns roaming call rates within the EU with those applied in France. Specifically, a call to +33 9 69 39 39 00 from an Orange mobile while roaming in the EU is treated as a national call. For plans that include unlimited calls, the call incurs no extra cost.
Outside the European Union, the bill entirely depends on the agreement between Orange and the operator of the visited country. Checking the pricing grid of your destination before calling avoids unpleasant surprises on the next bill.
3900 and 3901: the distinction between personal and professional service
The 3900 is exclusively for individual customers and prospects. Professional customers have a separate number, 3901, with different hours and service levels.
- The commercial service of 3901 is accessible from Monday to Saturday, from 8 AM to 7 PM (one hour less than 3900)
- Technical assistance and fault tracking via 3901 operate 24 hours a day, 7 days a week, which is not the case for 3900
- Sosh customers, Orange’s low-cost brand, do not fall under 3900 or 3901: Sosh has its own support channel, primarily online
Calling 3900 with a professional contract does not block the call, but the voice server generally redirects to 3901 after identifying the line number.
Alternatives to 3900 outside of 8 AM to 8 PM hours
When advisors are not available, several channels remain active. Djingo, Orange’s virtual assistant, answers common questions via the chatbot accessible from the Help and Contact page of the Orange website or from the Orange and Me app. This service operates without time restrictions.
The Orange and Me app also allows you to manage your account, check your bill, track your usage, or report a technical fault at any time. For requests that require written communication with a human, social media (notably Orange’s Facebook page) offers short response times during business hours.
Waiting times and actual cost of a call to 3900
As 3900 is a Crystal number, Orange does not charge anything for the call. With a plan that includes unlimited calls, the call to 3900 is completely free, including waiting time. On a limited or blocked credit plan, the communication is deducted at the price of a local call, but the waiting time itself is neither charged nor deducted from the credit.
Orange has been voted Customer Service of the Year 2026 for the second consecutive year, with the vast majority of calls handled in under a minute according to the associated study. This delay varies depending on the time slot: early mornings and late afternoons on weekdays concentrate the most simultaneous calls.
For simple requests (order tracking, bill balance, password change), the automatic voice server of 3900 processes the request without connecting to an advisor, even outside the opening hours of the human service.
