CPF.CNPJ or Serpro: which one to choose?

It depends on your use case. CPF.CNPJ is a commercial API with self-service signup and published per-query pricing, ideal for teams that want to integrate fast and estimate cost transparently. Serpro is the state-owned technology company and usually involves institutional contracting, common in public agencies and large contracts. Evaluate onboarding, integration, data coverage, support and pricing for your volume.

What is the difference between CPF.CNPJ and Serpro Datavalid?

Datavalid is a Serpro service aimed at validating registration data, accessed through institutional contracting. CPF.CNPJ is a commercial REST API for CPF and CNPJ queries with self-service signup, test credits and developer documentation. The choice depends on the contracting model and the data fields your flow needs.

Do I need a contract to use the API?

With CPF.CNPJ you can sign up self-service and start testing immediately with credits, without a prior commercial process. Access to Serpro products usually goes through an institutional contracting process. We recommend checking each provider current terms through the official channel.

Which one is easier to integrate?

CPF.CNPJ offers a REST API with JSON, token authentication and developer documentation, which tends to make integration straightforward. Serpro also provides APIs, with its own standards that vary by product. Perceived ease depends on the documentation of the specific service and your stack.

Does the data come from the Federal Revenue in both?

CPF.CNPJ delivers CPF and CNPJ queries with data from official sources. Serpro, as a state-owned technology company, operates services that connect to government databases. The exact scope of each database and product varies, so confirm the coverage and freshness of the data according to the service you intend to contract.

What to compare when choosing a CPF and CNPJ query API

When evaluating a CPF and CNPJ query API, product and engineering teams compare a recurring set of criteria: data source and freshness, ease of integration, response latency, pricing model, support quality and the time required to get started (onboarding). Each provider balances these factors differently, and the best choice depends on volume, use case and how much autonomy the team wants over the contracting process.

Serpro is the state-owned technology company that provides government data services, including solutions such as Datavalid and Infoconsulta aimed at validating and querying registration data. As a state-owned provider, access usually involves an institutional contracting process and integration with its specific products. CPF.CNPJ, on the other hand, is a commercial API with self-service signup. This page compares both options objectively, without attributing figures that cannot be publicly verified; differences between providers are described in qualitative terms.

CPF.CNPJ vs Serpro: comparison by dimension

1. Onboarding and contracting

With CPF.CNPJ, signup is self-service and immediate: you create the account, receive test credits and can run your first query the same day, with no prior commercial process required to start evaluating the API.

Access to Serpro products such as Datavalid and Infoconsulta typically goes through an institutional contracting process. This format can suit public agencies and large contracts, but tends to require more steps before the first test. Teams that prioritize getting integrating quickly usually value self-service onboarding.

2. Integration

CPF.CNPJ offers a REST API with JSON responses, token authentication and developer documentation, which makes it easier to integrate into backends, onboarding flows and batch validation jobs.

Serpro also provides APIs for its services, with its own documentation and standards. Specifics of authentication, payload format and integration model vary by the contracted product, so it is worth reviewing each service documentation for your use case.

3. Data coverage

CPF.CNPJ covers CPF and CNPJ queries, including registration data and the list of partners and administrators (QSA) for legal entities, supporting KYC, onboarding and enrichment use cases.

Serpro products cover different sets of government data depending on the contracted service. We recommend matching the scope of each product against your specific need to confirm the fields your flow requires are available.

4. Support and pricing

CPF.CNPJ works with transparent plans and published per-query pricing, with developer support during integration. The model makes it easy to estimate cost even before contracting.

Serpro pricing and terms vary by product and type of contracting, and are generally defined in the institutional contracting process. For this reason we do not attribute specific figures to Serpro here: we recommend requesting the terms directly through the provider official channel to compare based on up-to-date data.
