When the form won't submit without your date of birth

2026-08-21 · 2 min read

There is a particular kind of stuck that comes from filling in a broker's opt-out form, reaching the end, and discovering the submit button will not activate until you supply your date of birth. The listing you are trying to remove did not display your date of birth. You are being asked to add something to the record in order to take the record down.

It is not common. It is also not visible in advance, and that combination is what makes it worth writing down.

What we have actually seen

We record a broker's required fields only after observing its form refuse to submit without them — never from a privacy policy, and never inferred from what a site looks like it might want. On that basis these are the cases we can state:

• PropertyRadar will not submit without a date of birth and a phone number.
• Whitepages verifies by sending a one-time code to a phone, so a phone number is mandatory even though nothing in the flow is a form field.
• JailBase confirms by text message, with the same effect.

Treat that as a floor rather than a census. It is what has been established by filing, and any broker whose form we have not yet had reason to probe could join the list tomorrow without changing anything on its site that a reader would notice.

Why you cannot tell in advance

A broker's opt-out page almost never states its requirements. The fields appear as you go, validation happens at the end, and a requirement enforced by a disabled submit button is invisible until you have already entered everything else. There is no page to read that would have warned you.

That is also why this information is difficult to find anywhere. It is not published by the brokers and it cannot be scraped from their pages; it can only be learned by trying, which means somebody has to have already tried.

What to do about it

• Decide before you start how you feel about handing a phone number to a company you are trying to leave. Declining is a legitimate choice, and skipping one broker is a decision rather than a failure.
• If you do supply it, use the number the record already contains rather than a new one. Adding a phone number a broker did not previously hold is the outcome worth avoiding.
• Where a per-broker guide exists, the requirement is stated at the top, so you know before you open the form rather than after.

A form's requirements can change without notice and without any visible change to the page. What is recorded here describes August 2026.
