How to create your LlaveMX account for the PUI
LlaveMX is the Mexican government’s free single digital identity. It is the key to access the official portal where you will later register your establishment in the Single Identity Platform. Here we explain what it is, how it is created in minutes with your CURP, phone, email and password, how it differs from the e.firma, and its exact role in the PUI.
What LlaveMX is and what it’s for in the PUI
LlaveMX is the single digital identity Mexico’s government provides to access online procedures and services. It is free, personal and unique: a single account identifies you across different government portals. It works as your official "username and password" for the State’s digital ecosystem.
In the PUI, LlaveMX is the access key: it is the credential with which you will enter the official portal to manage your establishment’s profile, your notifications inbox and, when the time comes, request interconnection. It is not the legal signature (that is the e.firma); it is the access.
Creating your LlaveMX is one of the simplest and fastest steps of the whole process, and it does not depend on the pending manual. So it’s worth getting it ready now, alongside the e.firma, to arrive prepared for the interconnection window when it opens.
The essentials about LlaveMX
Four ideas so you don’t confuse it with other credentials.
It’s free and from the government
Mexico’s government provides it at no cost. No intermediary sells it and you don’t pay to create it.
It’s personal and unique
A single digital identity to identify you across different government services. It is not generic or shared.
It’s your access to the portal
It is the key with which you enter the official portal. For the PUI, that’s where you manage your profile and institutional inbox.
It is not your legal signature
LlaveMX gives you access; the e.firma gives legal validity. They are different and you need both for the PUI.
How it is created, in minutes
The process is quick. Here is what you generally need on hand.
- Have your CURP readyLlaveMX is tied to your CURP, your Unique Population Registry Code. Keep it on hand before you start.
- Have an active phone and emailThey are used to verify your identity and to receive notifications and codes. Use accounts you actually have access to.
- Set a strong passwordChoose a robust password that only you know. It is your access to the government portal: treat it as sensitive.
- Complete registration and store your detailsWith CURP, phone, email and password, the account is created in minutes. Keep your credentials in a safe place and don’t share them.
LlaveMX and e.firma: how they relate
The two key PUI credentials, side by side, so you don’t mix them up.
LlaveMX = access
It lets you enter the government portal. It is free and created in minutes with CURP, phone, email and password.
e.firma = legal signature
It identifies you with legal validity to the platform. The SAT issues it and it usually requires an in-person procedure.
Individual
You use your individual file in LlaveMX, aligned with your personal e.firma and RFC.
Company
You use the company file in LlaveMX, aligned with the company’s e.firma and RFC.
Both together enable the PUI
With LlaveMX you log in and with the e.firma you sign. You need both to manage your establishment and request interconnection.
Notifications inbox
Inside the portal, your profile includes an institutional inbox where official notices arrive. Check it often.
