About United States Phone Numbers
United States uses the international dialling code +1. When dialling a number from abroad, prefix it with this country code after dropping the local trunk prefix (usually a leading zero).
Example format: a typical United States mobile number looks like +12125551234.
Our free lookup tool identifies the caller name and operator when available. It does not expose private information such as addresses or national IDs — our goal is to help you quickly decide whether to answer or return an unknown call.
