Identify the carrier, line type (mobile / landline / VoIP), validity, and formatting for any phone number worldwide. Clean JSON, one fast request per number.
Phone Lookup API tells you who carries a phone number and what kind of line it is. Send a number in E.164 format and get back clean JSON — whether it's valid, the carrier name, the line type (mobile, landline, or VoIP), the country, and both E.164 and national formatting — in a single fast request.
Use it to validate and clean phone lists, route SMS to mobile numbers only, flag VoIP numbers for fraud checks, and enrich CRM records with carrier and country. Works for numbers worldwide — pass any country's number in E.164 and get consistent, structured data back.
- Rated Excellent — 4.6 based on 25 reviews on Trustpilot. Our open source work is sponsored by 1000+ devs on GitHub.
The same lookup is also available on Apify and RapidAPI:
One request to the lookup API:
GET https://carrier-lookup-api.omkar.cloud/lookup?phone=+12128148373
{
"is_valid_number": true,
"line_type": "mobile",
"carrier": "Verizon Wireless",
"phone_number": "+12128148373",
"national_format": "(212) 814-8373",
"country_code": "US",
"calling_country_code": "1",
"mobile_country_code": "310",
"mobile_network_code": "012"
}The + in a query string must be URL-encoded as %2B, so phone=+12128148373 becomes phone=%2B12128148373.

Whether it's valid, the carrier/network name, the line type (mobile, landline, or VoIP), the country and dialing code, national and E.164 formatting, and — for mobile numbers — the MCC and MNC network codes.
The line_type field returns mobile, landline, or voip. Route SMS only to mobile, skip landlines, and flag voip numbers for extra fraud checks.
Yes. Pass any country's number in E.164 format (a +, the country code, then the number). The API returns the carrier, country, and formatting for numbers worldwide.
In a URL query string, + means a space — you must URL-encode it as %2B (so phone=%2B12128148373). Most HTTP libraries (like Python's requests) encode it for you when you pass the number as a parameter.
Every request is answered live against up-to-date carrier and numbering data — not a stale local file you have to download and maintain.
Email Verification API — the same clean JSON for email: check whether an address is valid, deliverable, disposable, or a role account, and catch typos before you send. Pair it with phone lookup to clean both columns of a lead list.

From one developer to another: If the Phone Lookup API saved you time, please star the repo.
Here's why it matters: most developers judge an API by its stars before trying it. Your star helps the next developer — someone deciding whether the phone data here is real and reliable — try it with confidence.
It takes only 1 second, and means the world to me.
