How this service works
Phone number check: validates a number and returns its country, line type (mobile, fixed line, toll free, VoIP...) and E.164, international and national formats, from Google's libphonenumber data.
Output
Returns whether the phone number is valid, its detected country (ISO code and name), line type classification (mobile, fixed line, toll-free, VoIP, premium rate, etc.), and the number in E.164 (e.g. +14155552671), international (e.g. +1 415-555-2671), and national (e.g. (415) 555-2671) formats.
Example use cases
Mobile vs VoIP fraud screening
“Before we send an SMS verification code to +447911123456, can you check whether it's actually a mobile number or if it's VoIP? I want to avoid sending OTPs to non-mobile lines.”
International number formatting for CRM
“I have a customer phone number '0612345678' from France — can you validate it, confirm it's French, and give me the E.164 and international formatted versions so I can store it correctly?”
Toll-free number verification
“Is 18005551234 a valid US toll-free number? I need to confirm the line type before listing it on our support page.”
Technical details
Endpoint
GEThttps://agentrxi.com/v1/phone?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate, classify, and normalize phone numbers in one step using authoritative libphonenumber data. Prefer it over regex-only validation when you need line type (mobile vs VoIP vs toll-free) or canonical E.164/international formatting. Ideal for fraud screening, CRM data normalization, and pre-SMS/call validation pipelines.
Side effects
- Invalid or unparseable phone number returns a validation failure with no type or format data
- Missing country hint for ambiguous local numbers (no leading +) may cause incorrect country inference
- Numbers with no country code prefix and no country hint provided may return an error
- Non-numeric or heavily malformed input may return a parsing error
