Frequently asked questions about calls in United States
How do I find out who called me from an unknown number in United States?
Type the number in the search box exactly as it appears on your phone. You will see what other people who got the same call say, which area or line type it belongs to and, if it belongs to a company or agency, its official number.
Does looking up a number cost anything?
No. Looking up numbers, reading comments and posting your own is free, with no sign-up and no lookup limits.
What should I do if I think the call was a scam?
Hang up, never share codes or passwords, and call the official number of the organization they claimed to represent. Then leave a comment on the number page to warn others and, if you lost money or data, report it to the authorities.
How do I dial a United States number from abroad?
From a mobile phone, type +1 followed by the national number. From a landline, replace the + with the exit code of the country you are in: 00 in most countries and 011 in the United States and Canada.
Can I ask for my number page to be removed?
Yes. If the number is yours you can claim its page to add official information, or request its removal through the “Remove number” link in the footer. We verify every request by email.
