Example Argentina phone numbers
These are the example numbers from Google’s libphonenumber data, the same numbering-plan data our validator uses, written three ways.
| Format | Mobile | Landline |
|---|---|---|
| National (inside Argentina) | 011 15-2345-6789 | 011 2345-6789 |
| International | +54 9 11 2345 6789 | +54 11 2345 6789 |

How to write a Argentina 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 Argentina.
- Put +54 in front. The result has 10 or 11 digits after the country code for a mobile.
Argentina mobiles don’t follow that rule exactly: the domestic form 011 15-2345-6789 is written +5491123456789 in E.164, so compare the two columns in the table above rather than only removing the prefix. A validator that uses libphonenumber handles the conversion for you.
Mobile or landline?
Argentina 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.
