Service provider, contractor, third party (CCPA): Under the CCPA, a service provider processes personal information on a business's behalf, and a contractor receives it from the business for a business purpose; both need a written contract with the terms in Cal. Code Regs. tit. 11, § 7051(a). A third party is anyone who is neither the business, a service provider nor a contractor. The contract, not the vendor's own label, decides which one a recipient is.

A client's security questionnaire asks: "Are you a service provider, contractor or third party under the CCPA?" Or a client's counsel insists on one label in the contract. If you run a data or API business, the answer shapes what you can do with the data and what paper you have to send.

This page sets the three CCPA roles side by side, from the vendor's side. It covers the statutory definitions, the contract each role needs, and the limit on cross-context behavioral advertising that matters most to media and ad-data vendors. It explains the tests; which role applies to your business is a question for your counsel.

The contract decides the label

A vendor doesn't become a service provider by saying so in a questionnaire. The regulations tie the role to the paper. Section 7050(e) reads:

"A person who does not have a contract that complies with section 7051, subsection (a), is not a service provider or a contractor under the CCPA. For example, a business's disclosure of personal information to a person who does not have a contract that complies with section 7051, subsection (a), may be considered a sale or sharing of personal information for which the business must provide the consumer with the right to opt-out of sale/sharing."

That is why clients push for the paper. If the contract is missing or incomplete, your client may have a sale or sharing on its hands, with the opt-out obligations that come with it. The statute builds the same test into the definitions: a service provider and a contractor are each defined by a written contract containing specific prohibitions (Civ. Code § 1798.140(ag)(1) and (j)(1)).

The nine terms a § 7051(a) contract must contain are covered in what US state privacy laws require in a processor contract. The difference worth knowing here: the statute's contractor definition also requires "a certification made by the contractor that the contractor understands the restrictions" and will comply with them (§ 1798.140(j)(1)(B)). The service-provider definition has no such certification.

What must a third-party contract say?

A business that sells or shares personal information with a third party must have an agreement with it. Section 7053(a) lists six terms. The agreement must:

  1. identify the "limited and specified purpose(s)" for which the information is made available, described specifically rather than "referencing the entire contract generally";
  2. specify that the information is made available only for those purposes, and require the third party to use it only for them;
  3. require the third party to comply with the CCPA and the regulations, including providing "the same level of privacy protection as required of businesses";
  4. grant the business the right to take reasonable and appropriate steps to ensure the third party uses the information consistently with the business's obligations;
  5. grant the business the right, upon notice, to stop and remediate unauthorized use;
  6. require the third party to notify the business if it determines it can no longer meet its obligations.

Without such a contract, § 7052(a) says the third party "shall not collect, use, process, retain, sell, or share the personal information that the business made available to it." And § 7053(b) adds that a business that "never enforces the terms of the contract" may not be able to rely on the defense that it had no reason to believe the third party would misuse the data.

Put your CCPA terms on one page, send them to every client, and keep a record of who accepted which version.

Where ad and media data vendors get caught

Cross-context behavioral advertising is the one service a service provider or contractor can't provide. Section 7050(b) says:

"A service provider or contractor cannot contract with a business to provide cross-context behavioral advertising."

It continues: a service provider or contractor "may contract with a business to provide advertising and marketing services", but it "shall not combine the personal information of consumers who have opted-out of the sale/sharing" that it receives from the business with personal information it receives from another person or collects itself. And: "A person who contracts with a business to provide cross-context behavioral advertising is a third party and not a service provider or contractor with respect to cross-context behavioral advertising services."

The statute defines cross-context behavioral advertising as "the targeting of advertising to a consumer based on the consumer's personal information obtained from the consumer's activity across businesses, distinctly branded internet websites, applications, or services" other than the one the consumer intentionally interacts with (Civ. Code § 1798.140(k)).

The regulation's own examples draw the line. A social media company acting as a service provider can serve a clothing company's ads to an audience based on aggregated or demographic information, "However, it cannot use a list of customer email addresses provided by Business S to identify users on the social media company's platform to serve advertisements to them." An advertising company can place a cookware brand's ads on recipe websites as contextual advertising.

So a media or ad-data vendor may be a service provider for one service and a third party for another, under the same client relationship. Which side of the line a given service falls on is a question for counsel.

Sending the right terms to every client

Once you know which terms each client relationship needs, the work is getting every client onto them and keeping them current. California is the focus here; other states use "processor" and "third party" differently, and the state-by-state contract requirements guide sets them out.

Yesmark handles the sending. You put your service-provider terms on Yesmark as one standard text, and each client contact gets a private link to a page where they read and accept it, with no account. When the terms change and you publish a material new version, Yesmark drafts a re-acceptance campaign to every client not yet on it. The coverage board shows which clients are on the current version and which aren't. Yesmark for data and API vendors shows the setup, and when a client asks if you're a CCPA service provider covers that moment.

Frequently asked questions

Can a vendor be a service provider for one client and a third party for another?

The regulations tie the role to the contract and the service. A person without a § 7051(a)-compliant contract "is not a service provider or a contractor" (§ 7050(e)), and one providing cross-context behavioral advertising is a third party for that service (§ 7050(b)). How that applies to a particular vendor is a question for counsel.

What is the difference between a CCPA service provider and a contractor?

A service provider processes personal information on a business's behalf (Civ. Code § 1798.140(ag)); a contractor is a person to whom the business makes it available for a business purpose (§ 1798.140(j)). Both need the § 7051(a) contract terms, and the regulations apply the same use limits to both. The statute also requires a contractor's contract to include its certification that it understands and will comply with the restrictions.

Does a third party need a contract under the CCPA?

If a business sells or shares personal information with it, yes: § 7053(a) requires an agreement with six terms. Under § 7052(a), a third party without one "shall not collect, use, process, retain, sell, or share" the personal information the business made available to it.
