How to opt out of data brokers
A data broker is a company that collects information about you from public records and from other companies, and sells it. Most of them you have never heard of, and none of them asked you. You are allowed to tell them to stop, and this page is how.
The short version
Almost every data broker takes an opt-out request by email, and almost all of them use the same shape of process:
- Write to the address the company publishes for privacy requests, and say that you are opting out of the sale and sharing of your personal information, and asking them to delete what they hold.
- Give them enough to find you — usually your full name, your current address, and any address you have had in the last few years.
- Answer their verification email. They will send one, and they will not act until you reply.
- Keep the reply. It is your evidence of the date you asked.
California’s Civil Code §1798.135(c) gives a company 45 days to answer a request like this. We are a California company and we file every request that way, for everyone. If you live elsewhere, your own state may give you a similar right and may not — but most of these companies answer the request either way.

How many of them there are
We write to 637 companies on behalf of a customer, covering 642 websites — some companies run several. Counted from our published list on 2026-07-30, not rounded up. See /coverage for the working.
That number is the honest problem with doing this yourself. Any one of them takes ten minutes. All of them takes a season, and then it starts again.
Not sure which of them have you?
That is the part worth doing first, and it is free. One email address, about 15 seconds, no account and no card. You see which of your details have leaked and where they are published, and you can decide about everything else afterwards.
Or keep going by hand. Everything on this page works without paying us, and it is written so that it does.
