Where the data comes from

• Numbering data: the North American Numbering Plan Administrator (NANPA), which runs the plan's numbering resources under contract to the FCC: the area code database, the central office code assignment records and the rate center report.
• FCC complaints: the Federal Communications Commission's “CGB - Consumer Complaints Data” on opendata.fcc.gov, released under the licence “Public Domain U.S. Government”.
• FTC reports: the Federal Trade Commission's “Do Not Call (DNC) Reported Calls Data”, published every weekday. Works of the US federal government are not protected by copyright in the United States.

Before You Call Back is not affiliated with, endorsed by or acting for NANPA, the FCC, the FTC or any other government agency, and does not use their logos. The guides quote official pages and link to them; every page lists its sources with the date they were read. See how the site works.

What the data can and cannot prove

• Complaints are what consumers reported. The FCC and the FTC say they do not verify them. A number in the complaint data is a number that people saw on their caller ID or were given during a call, not proof that its subscriber made the call.
• Caller ID can be faked, so a real, innocent number can be reported.
• NANPA assigns exchanges to carriers, and pooled exchanges are shared out to other carriers in blocks of 1,000 numbers, so the carrier shown is the holder of the exchange, not always the company serving the number today.
• No public record says who holds a given number, and this site does not try to find out.

Data is shown as published, with its date, and refreshed regularly. It may contain errors or be out of date. Do not rely on it alone for a decision with legal or financial consequences.

Using the site

The site is free. Use it to understand calls and texts you received. Do not use it to harass anyone, to build lists of numbers, or to make decisions about a person's eligibility for credit, insurance, employment or housing. Automated bulk access is not allowed; the original data is available free from the agencies named above.

Corrections and removal

If something on a page is wrong, or you are the subscriber of a number and want its complaint details removed, write to contact@beforeyoucallback.com. See the privacy policy for how removal works.

Liability and law

The site is provided as it is. To the extent the law allows, GO TO AGENCY is not liable for decisions made on the basis of its content. These terms are governed by French law. If you are a consumer, this does not take away the protection of the mandatory rules of the state or country where you live.
