How to Call Vietnam from France

Dial +84 (Vietnam's country code) followed by the local number. From France, use 00 as the international exit code, so the full number is 00 + 84 + area code + local number.

    DIALING RULES

    Vietnam Dialing Rules and Number Formats

    Vietnam uses a specific numbering structure. Understanding these rules ensures your call connects reliably.

    Vietnam Country Code is 84

    Always use +84 or 0084 when dialing from outside Vietnam. Drop the leading 0 from any Vietnamese number you may have written down.

    Area Codes are 2–3 Digits

    Landline numbers use geographic area codes (e.g., 24 for Hanoi, 28 for Ho Chi Minh City). These are always included in the full number.

    Mobile Numbers Start with 9 or 8

    Vietnamese mobile numbers begin with 9 or 8 followed by a two-digit carrier identifier (e.g., 91–99 for Viettel, 81–89 for Viettel or MobiFone). The remaining digits form the subscriber number.

    Landline Numbers are 7–8 Digits

    After the area code, landline subscriber numbers are typically 6–8 digits long. Total length after the country code is 9–10 digits.

    No Special Dialing for Toll-Free or Premium Numbers

    Standard international dialing applies. Some special numbers may not be reachable internationally, but most business and residential landlines and mobiles connect normally.

    Calling tips

    • Call during weekday business hours to reach offices and service centers.
    • Evening calls from France (around 8:00 PM–11:00 PM) reach Vietnam early morning; better for urgent contact.
    • Allow extra time for connection; international calls may have a slight delay.
    • Have the full number and extension ready before placing the call.

    Business etiquette

    • Greet formally and introduce yourself clearly; Vietnamese business culture values courtesy.
    • Avoid calling on Vietnamese national holidays (e.g., Lunar New Year in late January/February).
    • Speaking English is common in urban business settings, but confirming the language preference first is respectful.
    • If calling a first time, a brief email or message beforehand improves connection likelihood.

    TROUBLESHOOTING

    Troubleshooting and Connection Issues

    If your call doesn't connect, check these common issues and solutions.

    Number Not Connecting

    Confirm the full number is correct: +84 [area code] [local number] for landlines, or +84 [mobile prefix] [subscriber number] for mobile. Check for typos in the area code or number.

    No Internet Connection on Browser

    Sayfone requires a stable internet connection. Check your WiFi or broadband connection, or switch to a different network (e.g., mobile hotspot) and try again.

    Call Drops or Poor Audio

    Audio quality depends on your internet connection speed and stability. Move closer to your WiFi router, close other bandwidth-heavy applications, or try calling at a different time.

    Rate Shown on Screen Differs from Expected

    Rates may vary based on call type (landline vs. mobile) and any active promotions. The rate displayed in your Sayfone account before clicking 'Call' is always the rate you will be charged.
