Do I need to dial a special code to exit Mongolia?

Yes, dial 00 (Mongolia's international exit code) or use the + symbol on your phone before entering the country code.

How do I dial a mobile number in China?

Mobile numbers in China follow the format +86 1XX XXXX XXXX (11 digits after +86). Simply dial +86, then the 10-digit mobile number starting with 1.

What if the area code has a leading zero?

What's the best time to call?

Business hours in China are typically 9 AM – 5 PM (China Standard Time). Since Mongolia shares the same time zone, you can call during your local business hours. Early morning and late night calls may not reach the intended recipient.

IMPORTANT RULES

Dialing Rules for China

Follow these rules to ensure successful calls to China from Mongolia.

Always Include the Country Code

When calling from Mongolia, always dial +86 (or 0086) before the area code and number. Calls without the full country code will fail or route incorrectly.

Drop Leading Zeros from Area Codes

Chinese area codes sometimes include a leading zero. When dialing internationally, omit this zero. For example, Shanghai's area code is 021 domestically but becomes 21 when called from abroad.

Mobile Numbers Start with 1

All mobile numbers in China begin with 1 (e.g., 138, 139, 150, 159). These follow the 11-digit format: +86 1XX XXXX XXXX. They are dialed the same way as area-code-based landlines but include the full 11-digit sequence after +86.

Landline Numbers Vary by City

Landline numbers in China vary in total length depending on the city and area code. Major cities typically have 7–8 digits after the area code. Always verify the complete number before dialing.

Calling tips

Since Mongolia and China share the same time zone year-round, there's no need to adjust for time differences.
Business hours in China typically run 9 AM to 5 PM, Monday through Friday. Plan calls accordingly.
Avoid calling very early morning or late night unless prior arrangement has been made.
Mobile phones may have higher connection rates during peak daytime hours (9 AM – 5 PM).

Business etiquette

Begin with a greeting in Mandarin if possible, or a polite English introduction.
Identify yourself and your organization early in the call.
Respect the person's time; business calls should be concise and purpose-driven.
If calling personal contacts, a brief warm greeting is appreciated before moving to the main topic.

TROUBLESHOOTING

Troubleshooting & Potential Restrictions

Resolve common calling issues and understand what may prevent a call from connecting.

Call Doesn't Connect

Verify you've entered the full sequence: +86 (country code), area code (without leading zero), and the 7–8 digit number. Check that the number format matches your destination (landline vs. mobile). Some providers may require pauses between segments; try adding a brief pause after entering +86 and before the area code.

Poor Call Quality

International calls from Mongolia to China may occasionally experience latency during peak hours (9 AM – 5 PM China time). Try calling during off-peak hours, or ensure your internet connection is stable if using VoIP.

Special Numbers May Vary

Some special numbers, such as government hotlines, emergency services, or premium-rate numbers, may not work internationally or may have restrictions. Landlines and standard mobile numbers are the reliable targets.

Calling Through a Telecom Provider

If calling through a traditional Mongolia-based telecom provider (e.g., MobiCom, Unitel), confirm that international dialing to China is enabled on your account. Some plans may require advance activation or have per-call charges.
