Check the original carrier for any mobile number across 228 countries — real MCC/MNC operator data, no login, no cost. Built on the same lookup that powers 6X's own routing and Number Lookup API.
Prefix-based simulator — shows original network assignment, actual network may differ due to number portability (MNP). A number with no country code can match more than one country; we show every match rather than guess.
Any format works - with or without a country code, spaces, or dashes.
Your number's dial code and prefix are checked against real MCC/MNC operator data for 228 countries.
Country, original network, and every real MCC/MNC operator on file for that range — instantly, no page reload.
Confirm a number's country and likely network before placing an important call or campaign — catch a mistyped number early.
Spot-check numbers in a CRM or contact export for country/network mismatches before a bulk SMS or voice campaign runs.
This page is the free front-end demo of a real, free API endpoint — call the same carrier/line lookup programmatically from your own OTP flow, signup form, or CRM via the 6X API's Number Lookup endpoint, before you waste a paid OTP send on a dead or fake number. Full reference: docs →
Looking for the reverse — a number to use, not check? See international phone numbers for local and virtual DIDs in 245 countries.
Real prefix and MCC/MNC data across virtually every country with mobile coverage, not just a handful of major markets.
Shows the actual carriers on file for that number's MCC/MNC range, not a guessed or generic "mobile network" label.
A genuinely free tool - no account, no API key, no rate limit for normal human use.
The exact same data is available programmatically via the 6X API's free Number Lookup endpoint for wholesale accounts.
A carrier lookup (also called a mobile network lookup or HLR-style lookup) checks a phone number's prefix against real MCC/MNC (Mobile Country Code / Mobile Network Code) data to identify which carrier a number was originally assigned to and which country it belongs to.
Yes. Carrier Lookup on this page is completely free, with no login, no account, and no rate limit for normal human use. The same lookup is also available as a free API endpoint for approved 6X wholesale accounts.
This tool shows the original network a number was assigned to based on its prefix — real MCC/MNC operator data across 228 countries. Because of mobile number portability (MNP), a number's actual current network can differ from its original assignment if the owner has switched carriers.
MCC (Mobile Country Code) and MNC (Mobile Network Code) together uniquely identify a mobile carrier worldwide — the same numbering scheme GSM/SMS routing systems use to determine where to deliver a call or message.
This lookup is built for mobile numbers, which carry real MCC/MNC operator data. A landline number will typically show country and region information but not a specific mobile carrier, since landlines aren't assigned to a mobile network operator.
Yes — the exact same lookup used on this page is available as a free Number Lookup endpoint on the 6X API for approved wholesale accounts, so you can integrate carrier/network lookup directly into your own app or backend.
The same lookup this page uses is a free endpoint on the 6X API - register a wholesale account and call it directly.
