Mexican Sellers Attention: Detailed Process of RFC Authorization Verification is Here!
Yijia Overseas2026-6-22

Sellers who have received the Mercado Libre RFC verification email, take note! Recently, many sellers on the Mexican site have successively received RFC entity authorization and consistency verification notices, with many getting stuck in the authorization email, CSF email confirmation, and other steps.

If you still don't know how to operate, this article has organized the complete process for you: register an email to sign the authorization, confirm the CSF email information, and complete the RFC consistency verification.

It is recommended to handle it as soon as possible to avoid affecting the normal operation of the store due to verification issues.

1. Mercado Libre sends RFC verification notice

Sellers on Mercado Libre's Mexican site, pay attention! For accounts where the store entity and RFC tax number entity are inconsistent, the platform is gradually sending out RFC authorization verification emails.

Be sure to check the seller's backend notifications, registered email, and CSF email. After receiving the verification email, be sure to first confirm that the currently bound RFC information can pass the consistency verification. If it is confirmed that it cannot pass, do not start the verification process. Instead, go to the seller's backend to update the RFC information first and wait for the system to trigger a new verification email.

2. Confirm the verification deadline first

Enter the seller's backend notification center and view the key points of the RFC authorization verification notice:

Verification submission deadline.

It is recommended to handle it immediately after receiving the notice, rather than waiting until the last few days to operate.

3. Mercado Libre RFC verification steps

Step 1: Sign the RFC authorization document

If the registered email receives an RFC authorization email:

1. Open the email

2. Click the verification button

3. Sign the authorization document online

After completion, the system will automatically send a confirmation email. The RFC owner must complete the formal authorization.

Step 2: Confirm the CSF email information

After the authorization is completed, the registered email will receive a second email. At this time, you need to fill in:

1. Name of the RFC entity contact person

2. Contact email

3. Relevant confirmation information

Submit and wait for the CSF email to receive the verification email.

Step 3: CSF email signs the authorization

After the CSF email receives the email: open the email, click the verification link, and complete the authorization confirmation.

Note: Only after the CSF email completes the signing is the entire RFC verification process considered complete.

Special reminder, if the CSF email cannot receive emails: it may cause RFC verification failure. It is recommended to check in advance: whether the email is working properly, whether international emails can be sent and received normally, and whether there is spam email interception.

4. What are the consequences of not completing it?

According to the platform notice, the store may be subject to operational restrictions; some functions are affected; the tax rate of Mexican site stores increases by 36%. Sellers who have received the notice must handle it as soon as possible. Simply put, the RFC verification process is as follows:

① Check the backend notification

② Registered email signs the authorization

③ Fill in the CSF contact information

④ CSF email completes the signing

⑤ Verification completed

It is recommended that sellers check in advance whether the RFC information is consistent with the store entity to avoid subsequent business impact.
