How this service works
Look up which regions use a country calling code (+44, +1) or a region's code, dialing prefixes and national prefix.
Output
Returns the numeric calling code, a list of regions that share it (each with their ISO region code, national prefix, international prefix, and whether they are the primary region for the code), a flag indicating if the code is shared across multiple regions, summary and disclaimer text, attribution, and metadata about when the data was built.
Example use cases
Identify regions sharing a calling code
“I need to know which countries or regions all use the +1 country calling code — can you list them along with their national and international dialing prefixes?”
Get calling code for a specific country
“What is the country calling code for Germany (region DE), and what national prefix and international dialing prefix should I use when calling from there?”
Validate dialing details before sending SMS
“Before I send an international SMS to a UK number, can you confirm the calling code and national prefix for the GB region so I dial it correctly?”
Technical details
Endpoint
GEThttps://phone-tools.x402tookit.com/country-calling-codes?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve which regions are associated with a country calling code, or look up the calling code and dialing prefixes for a known ISO region — particularly when you need national prefix and international prefix details in addition to the code itself. Prefer this over general phone parsing endpoints when the goal is country/region-level dialing metadata rather than parsing a specific phone number string.
Side effects
- Missing both 'code' and 'region' query parameters returns an error or empty result
- Invalid or unrecognized calling code returns no matching regions
- Invalid ISO region code returns no result
- Degraded response flag set if underlying data source is partially unavailable
- Payment failure if x402 micropayment is not completed
