How this service works
Parse and validate any phone number in any format, identify its country, line type (mobile/landline/VOIP/toll-free/premium), carrier region, and return all standard format variants — so agents can validate contacts, normalize phone data, and classify line types without a paid telecom API.
Output
Returns a JSON object with: E.164 normalized number, national and international format strings, validity boolean, country ISO code and full name, line type (mobile/landline/VOIP/toll-free/premium), digit count, a numeric confidence score, a grade, and an array of findings with additional analysis details.
Example use cases
Example prompt
“Can you validate this phone number for me — +1 555 867-5309 — and tell me if it's real, what country it belongs to, whether it's a mobile or landline, and give me the properly formatted E.164 version?”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/phone-intel/analyzeWhen to prefer
Use this endpoint when you need free-tier phone validation with line-type classification (mobile/VOIP/toll-free) and multi-format normalization without subscribing to a paid telecom API like Twilio Lookup or Numverify. Especially useful for contact data cleanup, CRM enrichment, or fraud screening workflows where E.164 normalization and line-type detection are both needed in one call.
Side effects
- Unparseable number format returns is_valid=false with empty or null format fields
- Missing required 'phone' query parameter returns 400 error
- Ambiguous local number without country_hint may resolve to wrong country
- Very short or test numbers (e.g. 555 numbers) may return low score/grade
- VOIP numbers may not have reliable carrier region data
