Chinese Phone Number Format: How +86 Works

Introduction

You've got a number for a supplier in Shenzhen. It starts with a 0, has way too many digits, and your phone won't connect the call. Sound familiar?

The Chinese phone number format isn't complicated — but it follows rules that look nothing like North American or European numbering. One of them, the leading-zero rule, breaks more international calls than any other.

This guide walks through the whole system: how mobile and landline numbers are built, what +86 does, when to drop that leading 0, and exactly how to dial China from anywhere.

THE TWO NUMBER TYPES IN CHINA

Before any dialing, you need to know which kind of number you're holding. China has two, and they follow different rules.

Mobile Numbers

Mobile numbers are always 11 digits and always start with the digit 1. They contain no area code — a Chinese mobile number works the same nationwide.

This is the number type you'll see most often for business contacts.

Landline Numbers

Landlines combine a city area code with a local subscriber number. They're shorter than mobiles and tied to a specific city.

When written for local use, landlines carry a leading 0 on the area code — and that 0 is the source of most dialing mistakes.

HOW CHINESE MOBILE NUMBERS ARE BUILT

A Chinese mobile number breaks into three readable chunks. Once you see the pattern, the digit wall stops looking random.

The Three-Block Structure

The standard layout is 1XX-XXXX-XXXX — a three-digit prefix, then a four-digit block, then a final four-digit block.

• Block 1 (3 digits): the carrier prefix, always starting with 1
• Block 2 (4 digits): an area or batch identifier
• Block 3 (4 digits): the unique subscriber digits

What the Prefix Tells You

The opening prefix signals the carrier — China Mobile, China Unicom, or China Telecom. Valid mobile prefixes begin 13, 14, 15, 16, 17, 18, or 19.

So a number starting 138 or 159 is a mobile line. A number starting with anything else almost certainly isn't.

Why Mobiles Need No Area Code

Chinese mobile numbers are national. Whether the phone is in Beijing or Chengdu, you dial the same 11 digits — no city code attached.

HOW CHINESE LANDLINE NUMBERS ARE BUILT

Landlines work the opposite way: location is baked right into the number.

Area Code Plus Subscriber Number

A landline is an area code (2 or 3 digits) plus a subscriber number (7 or 8 digits). The biggest cities get the shortest codes.

The Leading Zero

Notice every area code above starts with 0. That 0 is a domestic trunk prefix — it tells China's network "this is a long-distance call inside China."

Keep that 0 for calls within China. Drop it for calls from outside China. That single rule prevents most failed international calls.

If your team places regular calls into China, a provider like My Country Mobile (MCM) handles +86 routing and the leading-zero logic automatically — no manual digit-juggling.

WHAT THE +86 COUNTRY CODE DOES

Every country has a dialing code. China's is 86, and you'll see it written as +86 or 0086.

When You Need It

You add 86 only when calling China from another country. The + (or your local exit code) tells the network the call is leaving your country; 86 tells it the destination is China.

Calling within China? You never use 86 — it's purely for international calls coming in.

The Plus Sign

The + is shorthand for "the exit code for wherever I'm calling from." On a mobile, typing + works globally. On a landline, you replace + with your country's actual exit code — 011 from the US, 00 from most of Europe.

HOW TO DIAL A CHINESE NUMBER — STEP BY STEP

Here's the full sequence, split by the two number types. This is where the leading-zero rule earns its keep.

Calling a Chinese Mobile From Abroad

Dial: exit code + 86 + the 11-digit mobile number. Mobiles have no leading 0 to remove, so nothing gets dropped.

Example from the US: 011 86 138 XXXX XXXX.

Calling a Chinese Landline From Abroad

Dial: exit code + 86 + area code without the 0 + subscriber number.

To reach a Beijing landline written locally as 010-8765-4321, you dial: exit code, then 86, then 10 (not 010), then 8765 4321.

COMMON MISTAKES TO AVOID

A few errors come up again and again. Knowing them saves a lot of "call failed" frustration.

Keeping the Leading 0 on International Calls

The most frequent mistake. The domestic 0 must come off when you dial from outside China — leaving it in misroutes the call.

Adding an Area Code to a Mobile

Mobile numbers are national. Tacking a city code onto an 11-digit mobile breaks it. Mobiles travel as-is.

Forgetting the Exit Code

The +86 alone isn't enough from a landline — you still need your own country's exit code in front of it. On mobiles, the + handles this for you.

Mistaking Number Length

If a number is 11 digits and starts with 1, it's a mobile. If it's shorter and city-bound, it's a landline. Treat them by the right rules.

WHAT TO DO NEXT

The Chinese phone number format comes down to one habit: identify mobile vs. landline first, then apply the leading-zero rule. Get those two right and the rest follows.

If your business calls or texts China regularly, manual dialing logic gets old fast — and one wrong digit means a lost connection. A virtual number and proper international routing remove the guesswork entirely.
