🇲🇽 Mexico RFC Validator

🚀 Validate Mexican RFC taxpayer identifiers in bulk. Format checks, date validation, and homoclave checksum for persona fisica and persona moral RFCs. CSV, Excel, JSON, XML.

🕒 Last updated: 2026-05-26 · 📊 10 fields per record · Unlimited bulk RFC validation · Persona fisica (13-digit) and persona moral (12-digit)

The Mexico RFC Validator runs a structural validation of Mexican Registro Federal de Contribuyentes (RFC) tax identifiers against the official SAT format specification. Each input RFC is checked for format, embedded date validity, and homoclave checksum using the SAT modulo-11 algorithm.

Both 13-digit persona fisica RFCs and 12-digit persona moral RFCs are supported. The scraper is offline and deterministic - no SAT account or network call is required. This makes it ideal for high-volume KYC pre-screening before hitting the rate-limited SAT verification page.

Target Audience / Use Cases

Who	Why
KYC/compliance teams	Pre-validate Mexican counterparty RFCs in bulk
Accounting and ERP integrations	Validate RFCs before submitting CFDIs
Lead generation teams	Clean RFC fields in Mexican prospect lists
Sales operations	De-dupe and validate Mexican customer records
Developers	Add Mexican tax ID validation to your app
Auditors	Sanity-check large lists of RFC values

📋 What the Mexico RFC Validator does

• Validates RFC format for persona fisica (13 chars) and persona moral (12 chars)
• Validates embedded birth/incorporation date
• Computes the SAT homoclave checksum and verifies the last character
• Returns a single isValid flag plus per-check details
• Handles bulk lists of any size
• Exports to CSV, Excel, JSON, or XML

💡 Why it matters: Mexican CFDI invoicing requires valid RFCs. Pre-validating RFCs in bulk saves time and prevents downstream invoice rejections from SAT.

⚙️ Input

Field	Type	Default	Description
maxItems	integer	10	Maximum records to process
rfcList	array	[...]	List of RFC strings to validate

Example 1 - Validate a batch of RFCs:

{
    "maxItems": 100,
    "rfcList": [
        "XAXX010101000",
        "BIMB400702BS6",
        "MELM8305281H0"
    ]
}

Example 2 - Validate a single RFC:

{
    "maxItems": 1,
    "rfcList": [
        "XAXX010101000"
    ]
}

⚠️ Good to Know: This is a structural validator, not a live SAT lookup. It confirms the RFC is well-formed but does not verify the taxpayer exists in SATs database. For live SAT verification, use the SATs official "Verifica tu RFC" page.

📊 Output

Each record contains up to 10 fields:

Field	Type	Description
🆔 rfc	string	Normalized RFC (uppercase, no spaces)
👤 tipo	string	persona_fisica or persona_moral
✅ isValid	boolean	True if format + date + checksum all pass
📋 isFormatValid	boolean	Regex format passes
📅 dateValid	boolean	Embedded date is valid
🔢 checksumValid	boolean	SAT modulo-11 checksum passes
📅 birthDate	string	Parsed birth/incorporation date
📏 length	integer	RFC length (12 or 13)
🔗 sourceUrl	string	Link to SAT RFC reference
🕒 scrapedAt	string	Timestamp

Sample record:

{
  "rfc": "XAXX010101000",
  "tipo": "persona_moral",
  "isValid": false,
  "isFormatValid": true,
  "dateValid": true,
  "checksumValid": false,
  "birthDate": "2001-01-01",
  "length": 13,
  "sourceUrl": "https://www.sat.gob.mx/aplicacion/operacion/27091/verifica-tu-rfc",
  "scrapedAt": "2026-05-26T12:00:00.000Z"

❓ Frequently Asked Questions

What is an RFC? Registro Federal de Contribuyentes - the Mexican tax identifier issued by SAT.

What is the difference between persona fisica and persona moral RFC? Persona fisica = individual (13 chars). Persona moral = company (12 chars).

Does this verify the RFC exists in SAT? No. It only validates the structure. For live verification, use SATs official tool.

What is the homoclave? The last 3 characters of the RFC. Calculated by SAT using a modulo-11 algorithm on the rest of the RFC.

Can I validate RFCs in bulk? Yes. Pass any number of RFCs in the rfcList input.

How fast is the validator? Thousands of RFCs per second.

Does it work offline? Yes. No network call is made to SAT.

Are special characters supported? RFCs use A-Z, 0-9, Ñ, and & only.

How many records per run? Free: 10. Paid: up to 1,000,000.

Can I export to Excel? Yes.

Why might a valid RFC return checksumValid=false? SATs checksum uses a non-standard character table. Make sure the RFC is uppercase and contains no extra characters.
