ProspectBase Opt Out: California Form and Email Route

For a ProspectBase opt out, California residents can use the form at prospectbase.com/ccpa with their business email address, name and phone number. The page says submitting it exercises an opt-out and requests removal from ProspectBase’s databases. It requires confirmation that you live in California. If you do not, contact privacy@prospectbase.com about the appropriate route instead of selecting a false declaration.

We checked the public form on September 21, 2026. This guide describes its visible requirements; no consumer request, email confirmation or completed removal was tested.

ProspectBase opt out quick facts

ProspectBase’s public page is useful because it states its scope before collecting information. Those conditions should remain part of the instructions, rather than being hidden in a footnote after a generic fill-in-the-form step.

For other providers, start with the opt-out guide hub. A privacy request belongs with the organization responsible for the relevant information; one company’s form does not cover every professional directory.

Check whether this form fits your situation

Open the official ProspectBase CCPA page. Its heading concerns selling or sharing personal information, and the introduction explicitly limits this form to residents of California, United States.

The page also instructs you to use a business email. It says ProspectBase does not hold personal email details for matching through this route. That is the provider’s stated matching boundary, not a reason to invent a work address or use a coworker’s mailbox.

If you live elsewhere, use the published privacy contact to ask how to exercise your applicable choices. Explain your location and the record you want addressed. The presence of a California-only form does not, by itself, establish that everyone else lacks a request route.

If you recently changed jobs, the identifier associated with an older record may differ from the address you use now. Explain that difference rather than assuming a request against a new address also finds every historical business contact.

The data broker explainer describes why professional details may exist outside a public people-search page. You do not need to invent a profile URL when the form does not ask for one.

Complete the California form

Use the privacy form beneath the instructions, not a sales enquiry or newsletter control elsewhere on the website. The browser check found required fields for First name, Last name, Email and Phone number.

• Enter your own first and last name as they relate to the professional record.
• Enter the business email address relevant to the request.
• Enter the requested phone number, checking it for typing errors.
• Confirm California residence only if that statement is accurate.
• Review the details and use the form’s submit control when ready.

A security check may also appear. Complete the normal page controls yourself if required. We inspected the public form and did not test CAPTCHA completion or final submission, so this guide does not promise a specific confirmation screen.

Before sending, keep a private note of the date and the identifiers used. Do not publish that note or share a screenshot containing your full contact details. A simple record makes a later follow-up possible without resubmitting everything from memory.

The form’s explanatory text says submission requests opt-out and removal from its databases. If you need a more specific answer about sale, sharing, retained records or separate marketing messages, ask the privacy team to clarify the scope in its response.

What if your work email is no longer accessible?

An old job can leave a record linked to an address you no longer control. Do not attempt to access that mailbox or claim it is still yours. Contact the privacy team from an address you control and explain which older identifier is relevant.

Ask what alternative verification is appropriate before sending documents. A former work address may help locate a record, but knowing that address is not the same as proving you are the person described by the record.

Similarly, a shared department mailbox may represent several people. Explain that context if you need a personal record corrected or removed. A request about your own details should not imply authority to remove colleagues or an entire organization’s data.

The general removal workflow includes keeping identifiers and outcomes separate. This is especially useful for professional records that change when someone moves employers.

Use the privacy contact for other cases

The CCPA page publishes privacy@prospectbase.com for questions about processing personal information. Use it if the California form does not fit your location, if required details are unavailable, or if a technical problem prevents you from using the documented route.

A concise message can identify your request, your location and the business identifier involved. Ask which process applies and whether any verification is needed. Avoid adding unrelated personal history, passwords or payment details to a first enquiry.

If you already submitted the form, include its date and reference if available. Keeping the same email thread helps distinguish a follow-up from a new request. Ask for a clear explanation of the action taken and any information that remains.

ProspectBase also links policies for its UK and Ireland operations. The UK policy’s California section confirms the email and website form routes, but its sale wording is inconsistent across sections. Request the specific deletion and use restrictions you want rather than inferring that one general statement settles every activity.

Timing, verification and confirmation

The form says the privacy team will process requests as quickly as possible. The linked UK policy’s California section is more specific: it describes a response generally within 30 days, no later than 45 days, with notice if more time is needed. These are provider-stated response periods, not a measured deletion time.

Watch the email address you supplied for legitimate correspondence and check spam folders. If a verification message arrives, compare it with your actual request and the official contact. This guide does not assert that a particular verification email is always sent.

Read the eventual response for the identifier matched and the scope of action. A receipt confirms a request arrived; a detailed completion response provides stronger evidence of what happened. If the reply is unclear, ask whether both the opt-out and database-removal elements were addressed.

If you cannot find a reply, check delivery failures and your original details before resubmitting. An incorrect business address may prevent a useful match. Ask the privacy team about status rather than assuming silence proves either successful removal or refusal.

Database removal and email unsubscribe are different

A marketing email may offer an unsubscribe control. That can address further messages through the relevant mailing process, but it is not automatically confirmation that a broader professional record was deleted from every database.

Conversely, a database request does not explain the status of every campaign already sent or every independent customer copy. If a specific sender continues to contact you, ask that sender to stop and to identify the source of your details.

Related providers have their own routes. The SalesIntel opt-out guide covers another professional-data request, while the Demandbase guide addresses a separate provider. These are relevant next steps only where there is a reason to contact them.

Do not infer that ProspectBase supplied a particular sender solely because both operate in business marketing. A source disclosure, relevant record or provider reply is more useful evidence than a guess based on an unwanted email.

Keep a record and review later changes

Save the response and the business identifiers it covers. If you move jobs, change phone numbers or encounter a different record, compare the new situation with the scope of the original action. That avoids assuming every future identifier was already addressed.

The linked policy says certain information remains in a suppression file to restrict future processing in line with your preferences. That retained record has a different purpose from a contact used for marketing. Ask the response to explain which information remains and how the restriction applies.

The data broker opt-out list helps organize additional provider requests. Keep each result separate instead of marking your whole online footprint removed after one response.

A free privacy scan can help locate supported public exposures. It does not search ProspectBase’s internal databases or certify completion of this request. Use the scan and provider correspondence for the different questions each can answer.

Frequently asked questions

Can I use a personal email address?

The current CCPA page explicitly asks for business email and says personal email will not match its records. If that requirement does not fit your situation, ask the privacy contact about an alternative rather than submitting an invented address.

Is the form available outside California?

The page can be viewed publicly, but its request declaration is for California residents. Other readers should ask the published privacy team which route applies to them. Do not make an inaccurate residence declaration.

Does the form require a phone number?

Yes, the phone field was required in the browser check. We did not test exceptions after submission. If you cannot provide an appropriate number, contact the privacy team before attempting to work around the requirement.

Do I need a ProspectBase account?

No login was needed to view the public form. That does not settle what identity verification may follow a request. Keep access to the email used for correspondence where possible.

How do I know the request is complete?

Look for a response that identifies the action and its scope. A receipt alone does not prove deletion. If the answer does not address removal or continued use clearly, ask for clarification in the same thread.
