New Service: RFC Validation and Extraction from the SAT in Mexico

New Service to run validity checks on a single or a group of companies’ RFC’s, names and addresses.
When to use: When you want to ensure that the RFC is a valid number and belongs to the person or entity claiming it.
Cost to use:
Option 1: On Demand
$40 MXN per validation
Option 2: Purchase Package
$40,000 MXN for 10,000 validations
Introduction:
CRiskCo is introducing a new service to validate and extract the Mexican Tax Identification Number (RFC) from the Mexican Tax Authority (SAT). Registro Federal de Contribuyentes (RFC) validation is a process used in Mexico to verify the validity of a taxpayer identification number issued by the Mexican government. The RFC is a unique number assigned to individuals and businesses that are required to pay taxes in Mexico. The validation process checks the format and structure of the RFC to ensure that it is a valid number and belongs to the person or entity claiming it. This validation is important for businesses and individuals to verify the identity of customers, suppliers, reduce frauds and identify fake accounts. We recommend the usage of this service on the entire ecosystem of your targeted applicant/client/supplier. Within a few minutes you can check the entire network of the company.
The new service provides real-time validation by checking it against the SAT’s database. This will help to reduce the risk of errors and fraud in financial transactions and improve the accuracy of the data being used.
Process to validate an RFC:
Our RFC Validation service is available through API usage only at this time. There are two options to use the service:
- By validating one RFC at a time (SAT – RFC Validation endpoint ).
- By validating bulk of RFC’s up to 5,000 in a single call (SAT – RFC Validation Bulk endpoint ).
In every call you are able to validate with SAT in real-time the following:
- RFC is correct and active
- Name of the company match the RFC
- Company postal code is correct
The API request can include:
Individual RFC –
Option 1 – RFC Only:
URL/service.svc/ValidateRFC?rfc=XXX00000
Option 2 – RFC, Name and Postal Code : URL/service.svc/ValidateRFC?rfc=XXX00000&name=TEST&postal=12345
Bulk RFC
URL/service.svc/ValidateRFCBulk with File in body
The file in the body of the request will include the RFC and other details, separated by characters that will be defined in the documentation of the service.
The response will return if the request is successful or not, 3 optional boolean values and the response message from SAT (as you can see below in the example):
Success – Is the request is successful or not
ValidRFC – The RFC is valid or not
ValidName (if requested) – The Company Name is valid or not
ValidPostal (if requested) – The Postal Code is valid or not
message – The exact message from SAT

Costs
If you are not sure how many RFC validations you require you can pay per call an amount of 20 MXN.
We recommend purchasing a package of 10,000 calls at 80% discount for 40,000 MXN, making it extremely cost effective, with only 4 MXN per call.
Bulk calls and single API calls are billed with the same packages. For example a bulk call with 1,000 RFC’s will be charged as 1,000 API calls.
For billing information and registration to the service, reach out to sales@criskco.com.
