Phone prefix by country ISO code
What this tool does
This tool looks up the international dialing code for a phone number based on a two-letter country code (e.g. ES for Spain). You enter the country code, and the platform returns the prefix used to call that country from abroad.
The platform uses a built-in list of known country codes. If the code you enter is not found in this list, the tool returns an empty result rather than an error message.
Common uses
- Adding the correct international prefix when formatting phone numbers for international contacts.
- Verifying which dialing code belongs to a specific country for documentation or data cleaning.
