China Phone Numbers: Format, Rules, and Calling Abroad

TL;DR: The 30-Second Version

The 1 that starts every Chinese mobile number is not random, and the way locals read the rest out loud follows rules nobody bothers to teach newcomers. Learn them once and the fumbling stops at shop counters, WeChat verifications, and delivery apps.

• Mobile numbers: 11 digits, always start with 1.
• First three digits tell you the carrier, not the city: 134-139 China Mobile, 130-132 China Unicom, 133 China Telecom.
• Read every digit separately, and say 1 as “yao” (like “yow”) so nobody mistakes it for 7.
• Save every contact as +86 followed by the number.
• Calling China from overseas on a landline: drop the leading 0 (010 turns into 10).

The Short Answer

The short answer: a Chinese mobile number is 11 digits, always starts with 1, and is best saved and dialed as +86 plus the full number. For landlines, dial the area code without the 0 from outside China. That covers most of what actually matters.

How Locals Read Numbers Out Loud

You’ll notice it the first time a shop assistant reads your number back: they go digit by digit, never in the pairs Westerners tend to use. One three eight, one two three four, five six seven eight. No “thirteen-eighty” shortcuts, ever.

And that 1? Say “yao”, not “yi”. China’s phone system can’t risk the mix-up: over a crackly line, yi and qi (seven) sound dangerously close. So phone calls, hotel room numbers, and even train announcements use “yao” for the number 1. You’ll hear it within your first week.

In your head, group the digits the way locals do: 138-1234-5678. It makes the number far easier to verify against what the courier just said.

What the First Three Digits Tell You

Chinese mobile numbers carry no city code — the first three digits identify the carrier instead. The classics: 134-139 is China Mobile, 130-132 is China Unicom, 133 is China Telecom. Newer prefixes (147, 166, 199, and friends) keep appearing as the carriers grow, but the shape is always the same: 1, then a three-digit carrier prefix, then eight more digits.

One honest caveat: since 2019, number portability lets people switch carriers and keep the same number, so a number starting with 138 might now live on a Telecom SIM. The prefix is a hint, not a guarantee.

Save Contacts the Way That Survives

Store every Chinese number with +86 in front. Always. The reasons stack up: it works when you fly home, it works when you land back, and apps like WeChat and WhatsApp match contacts in full international format anyway. A contact saved without the country code is a contact that will quietly fail in half the places you need it.

Calling China From Overseas

For a mobile, it’s +86 then the 11 digits, no gaps. For a landline, +86 then the area code without the leading 0 — Beijing 010 becomes 10, Shenzhen 0755 becomes 755 — then the subscriber number.

In practice, we barely dial at all anymore. WeChat voice and video calls ride on data, cost nothing extra, and reach anyone in China with the app, which is everyone. For actual international calls, home-carrier roaming rates change every couple of years and are usually a bad deal; buy a China data plan instead, or grab a travel eSIM (Airalo and Holafly both sell China eSIMs you install before you fly) and skip the dilemma entirely.

Landlines and Area Codes You’ll Actually Meet

You’ll rarely dial a landline, but when forms ask, these are the ones: Beijing 010, Shanghai 021, Guangzhou 020, Shenzhen 0755. And 400 numbers — the ones on every business website — are national corporate hotlines, fine to call from a Chinese SIM. Your hotel front desk will happily dial anything for you anyway; that’s half their job.

The Numbers Worth Memorizing

Three emergency numbers work from any phone, free: 110 police, 119 fire, 120 ambulance. Then add these: 10086 for China Mobile service, 10010 for China Unicom, 10000 for China Telecom, 12306 for rail tickets, and 12345, the city government hotline that actually picks up.

Getting a Number as a Foreigner

Real-name registration is mandatory in China: a SIM in your name means your passport, full stop. The easy path is the carrier counters just outside airport arrivals, which sell prepaid tourist SIMs with data on the spot, or any China Mobile, Unicom, or Telecom store downtown. For a short stay, skip the counter with an eSIM bought online before boarding — it activates the moment you land.

Quick Answers

Q: How many digits is a Chinese mobile number? A: 11 digits, always starting with 1.

Q: Why do Chinese people say “yao” for 1 in phone numbers? A: Because 1 (yi) and 7 (qi) sound too similar over a bad connection. Saying “yao” removes the confusion.

Q: Should I save Chinese contacts with +86? A: Yes. +86 plus the 11 digits works everywhere; without it, the contact fails abroad.

Q: What is the emergency number in China? A: 110 for police, 119 for fire, 120 for ambulance — all free from any phone.
