Smart global number lookup · auto-detects country from the code, or pick a country
How it works: numbers with a + or 00 international prefix are matched by country code; without one, pick a country above (an 11-digit Chinese number starting with 1 auto-selects China). Type and validity follow each country's numbering rules; Chinese numbers also show the carrier (may differ after porting) and number patterns. City-level location would need a full number-range database, so this tool offers no guesses. All analysis is local.
