Cambodia phone number format
How do you format a Cambodia phone number?
Write a Cambodia phone number with the country code +855. A mobile looks like 091 234 567 inside Cambodia and +855 91 234 567 from abroad, dropping the leading 0. Mobiles have 8 or 9 digits after the country code, and the E.164 form is +85591234567. Format alone never shows a line is in service.
Free, runs in your browser; nothing is sent. The sample is a sample, not a real line.
Paste your Cambodia numbers (a mixed list is fine). They are counted here at once; the free checker then gives every number its E.164 form, country and line type, with a file to download.

| Trunk prefix (domestic dialling) | 0 |
| Mobile number length | 8 or 9 digits after +855 |
| Landline number length | 8 or 9 digits after +855 |
| Mobile vs landline from the digits | Yes, separate ranges |
In short: +855, 8 or 9 digits for a mobile, drop the leading 0 after +855. The checker below formats any Cambodia number free in your browser; it can't say whether a line is live. Bulk phone number validator · Pro + Phone plan

How to write a Cambodia number in E.164
- Remove spaces, dashes, dots and brackets so only digits are left.
- If the number starts with the trunk prefix 0, remove it. It is only used when dialling inside Cambodia.
- Put +855 in front. The result has 8 or 9 digits after the country code for a mobile.
So 091 234 567 becomes +85591234567. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.
Mobile or landline?
Cambodia allocates separate number ranges to mobiles and landlines, so a numbering-plan check reads the line type straight from the digits, for free. That type describes the range the number came from. It doesn’t prove the number is connected today.
Mobile, landline and special number ranges in Cambodia
A Cambodia mobile number starts with 1, 23–26, 31–36, 38, 42–44, 52–55, 6, 7, 80, 81, 83–89, 9 after +855. Every valid number of each type below starts with one of the digit groups shown. A number that starts the right way can still be unassigned: the groups say what a range is for, not that a number is connected.
| Type | Starts with, after +855 | Dialled inside Cambodia | Digits | Example |
|---|---|---|---|---|
| Mobile | 1, 23–26, 31–36, 38, 42–44, 52–55, 6, 7, 80, 81, 83–89, 9 | 01, 023–026, 031–036, 038, 042–044, 052–055, 06, 07, 080, 081, 083–089, 09 | 8 or 9 | +855 91 234 567 |

Common questions
- What is the country code for Cambodia?
- The country calling code for Cambodia is +855. When you call Cambodia from abroad, dial your international prefix (or +) followed by 855 and the number without its leading 0.
- How many digits is a Cambodia phone number?
- A Cambodia mobile number has 8 or 9 digits after the country code +855, the same as a landline. Written for dialling inside Cambodia, a number gains the trunk prefix 0 in front.
- How do I write a Cambodia number in international format?
- Start with +855, drop the leading 0, then add the rest of the number. The mobile number 091 234 567 becomes +855 91 234 567, or +85591234567 in E.164, the form most CRMs and SMS tools expect.
- Can you tell if a Cambodia number is a mobile?
- Usually, yes. Cambodia numbers come from ranges allocated separately to mobiles and landlines, so a numbering-plan check reads the line type from the digits. It tells you what the range is for, not whether the number is in service.
- Does a valid format mean a Cambodia number is in service?
- No. A valid format means the digits fit a range Cambodia's numbering plan allocates. It cannot tell whether the number is connected today or who carries it, because numbers are reassigned and ported. A live carrier lookup reports the current carrier and line type, but even that does not prove someone answers.
