How to Get a Mexican Criminal Background Check

To get a Mexican criminal background check, you request the Constancia de Antecedentes Penales Federales from the Órgano Administrativo Desconcentrado Prevención y Readaptación Social (OADPRS), Mexico’s federal prison and rehabilitation agency. If you’re in Mexico with a CURP, you can apply online for 240 pesos and often receive the certificate the same day.¹ If you’re abroad, the process runs through a Mexican consulate and a representative in Mexico, and usually takes two to four weeks.

Confirm Which Certificate You Actually Need

Mexico issues two different federal criminal record documents, and ordering the wrong one wastes time and money.

The Constancia de Antecedentes Penales (CANP) from the OADPRS is the standard document. It reports federal criminal convictions for offenses like drug trafficking, firearms violations, and organized crime. Most U.S. visa applications, employers, and foreign governments ask for this one.²

The Constancia de Datos Registrales (CDR) from the Fiscalía General de la República (FGR) is broader. Rather than only listing convictions, it shows whether your name appears in any prior federal or local criminal investigation, whether or not charges were ever filed. Canadian immigration authorities in particular tend to require the CDR.²

Check the exact wording of what the requesting authority asks for before you begin. State-level certificates also exist for offenses under local codes, but they’re separate documents issued by state prosecutors, not by the federal government, and they’re rarely what foreign institutions want.

Documents to Gather Before You Apply

If You’re a Mexican Citizen

Have these ready before you open the portal:

Your CURP (Clave Única de Registro de Población), the 18-character code assigned to every Mexican citizen and resident. Copy it from a digital source rather than typing from memory. Every character has to match.
A valid government photo ID, such as an INE voter credential or current Mexican passport.
Your birth certificate, including the registration book number and date of registration.
An active email address, which is where the system sends the download link for the finished certificate.

Your full legal name, including both paternal and maternal surnames, must match exactly across every document.³

If You’re a Foreign National Who Lived in Mexico

Foreign applicants face extra documentation. Typical requirements include:

Passport, original plus a copy of the biographical page.
Birth certificate, with an official Spanish translation if it’s in another language.
Two sets of rolled and flat fingerprints of all ten fingers, taken in black ink by an authorized agency, each form signed by both the officer and you.
Color photographs (3.5 cm × 4.5 cm) on a white background, one frontal and one right profile, without glasses, earrings, makeup, or facial hair.
Proof of legal immigration status during your time in Mexico: a copy of your visitor card, resident card, or passport entry stamps.

That last item catches many applicants off guard. If you can’t document that you were lawfully present in Mexico during your stay, the FGR will decline the request outright.⁴

Applying Online Through OADPRS

The only legitimate portal is constancias.oadprs.gob.mx. Ignore any third-party site that offers to process the certificate for you.¹

The portal walks you through the steps in order: enter your CURP, fill in your biographical details, upload identification data, choose a payment method, and confirm the transaction. The fee is 240 Mexican pesos, roughly $12 to $14 USD depending on the exchange rate. It’s set at the start of each calendar year and published on the OADPRS portal.³

You have two payment options. You can pay online through BBVA’s payment engine with a credit or debit card, or you can print a reference slip from the portal and deposit the fee at a bank window. If you pay at the bank, keep the receipt: you’ll need the operation number and transaction date to confirm payment during the final step.¹

Any mismatch between your CURP and the biographical details you type in will halt the process with an error. This is the most common cause of failed first attempts. Verify that your name, birth date, and parents’ names match the national population registry, not just what appears on your birth certificate; the two sometimes contain small discrepancies.

Processing Time and How Long the Certificate Lasts

Online applications usually process within minutes or a few hours. You’ll get an email with a secure link to download the certificate as a PDF. Applications filed in person at an OADPRS office typically take five to ten business days.

The downloaded PDF carries a QR code and electronic signature that let anyone verify authenticity against the OADPRS database. Point this out to whoever receives the certificate, because many foreign agencies don’t realize they can scan it directly.

Validity is limited, generally 30 to 90 days from issuance, and the exact window depends on what the receiving institution accepts. If the certificate expires before you use it, you have to reapply and pay again. Time your request against your actual deadline.

Applying From Outside Mexico

Mexican consulates abroad do not issue criminal record certificates. What they do provide are two things you can only get from a consulate: a consular support letter and witnessed authentication of a power of attorney so someone in Mexico can file on your behalf.²

The support letter is mandatory. Without it, neither the OADPRS nor the FGR will accept an application submitted by a representative. The consulate also witnesses your signature on a simple carta poder authorizing a relative or trusted contact in Mexico to file for you, with two consular officials signing as witnesses.

The process typically runs like this:

Schedule an appointment at your nearest Mexican consulate. Bring valid ID, your birth certificate, and proof of address.
At the appointment, the consulate prepares the support letter and witnesses your power of attorney. If you need the FGR certificate, the consulate also takes your fingerprints.
Send the completed documents to your representative in Mexico by reliable courier.
Your representative files the application at the OADPRS or FGR office in Mexico City.
Once the certificate is issued, your representative ships it back to you.⁴

The full cycle usually runs two to four weeks, longer if courier delays or FGR processing slow things down. Start early if you’re working against a visa filing deadline.

Apostille and Translation for a Foreign Government

Mexico has been party to the Hague Apostille Convention since August 14, 1995, so Mexican public documents can be apostilled for use in any other member country.⁵ If the country asking for your criminal record belongs to the convention, an apostille is the standard authentication. Non-member countries generally require full legalization through their embassy instead.

For federal documents like the CANP, the apostille comes from the Coordinación General de Política con Poderes de la Unión, under the Secretaría de Gobernación in Mexico City. Mexican consulates abroad cannot apostille documents.⁵ If you’re outside Mexico, the same representative who picks up your certificate needs to visit this office for the apostille before shipping it to you. Build that step into your timeline.

If you’re filing with USCIS, the certificate must include a full English translation with a signed certification stating the translation is complete and accurate and that the translator is competent to translate from Spanish into English. The certification has to include the date, the translator’s printed name, and their signature.⁶ USCIS does not require a professional translator; a bilingual friend or family member can sign the certification. Consular officers abroad and other agencies may set stricter standards. Professional certified legal translations typically run $25 to $75 per page, and the certificate itself is usually one or two pages.
