Background checks for Mexico

Yes. Zinc's instant employment verification in Mexico works by linking directly to the government tax controller system, rather than contacting referees manually.

The candidate has their CURP (Unique Population Registry Key), NSS (Social Security Number), and email ready, then signs into Zinc and enters their government login details — functionally the same as logging into the government portal itself in a pop-up window.

Zinc doesn't store or process those credentials: they're encrypted, used only to validate a one-time session, and never kept afterwards. The check then pulls up to 5 years of employment history straight from the government record, which is why it's much faster than traditional references. The government route is recommended but never mandatory. Candidates can opt out and provide traditional references instead, though that pushes turnaround out to 1 to 2 weeks. Nothing about the candidate's new job (employer name, title, start date) gets shared with anyone during the process, and no one is contacted at all unless the candidate separately submits a referee email.

Zinc combines two layers of checking to cover Mexico's tricky system. First, Zinc searches over 130 courts and tribunals across the country, including the Supreme Court, District Courts, and Circuit and Appellate Courts, plus government gazettes, sanctions and most-wanted lists, and each of Mexico's 32 state-level criminal databases.

Second, if a record shows a strong enough match, Zinc's trusted local legal partners follow up directly with the relevant authority to confirm the details in person: the charge, the case outcome, and whether it's still active. Zinc goes to these lengths because Mexico's system makes criminal checks less straightforward than in other countries. Most records are only accessible manually, some aren't reliably disclosed due to regional corruption, the courts aren't centrally connected, and there's no single legal standard for background screening in the country. The check covers citizens and foreign nationals aged 18 and over, nationwide.

Not identical. Zinc's Mexico screening focuses on verification, rather than the home visit and family interview format of a full estudio socioeconómico. Zinc's compliance team can help you understand how this fits with your existing hiring process.

The Federal Law on the Protection of Personal Data Held by Private Parties governs background checks in Mexico, requiring express consent from the candidate. Mexico's data protection enforcement body also changed in March 2025, when INAI was dissolved and its functions moved to the Secretariat of Anti-Corruption and Good Governance.
