Yes, a foreigner can obtain a CURP in Mexico, and in most cases you don't even have to order it separately. The CURP is the 18-character alphanumeric code that the State uses to register and identify each person in the National Population Registry, and it is assigned to both Mexicans and foreigners who are in or reside in the country. If you have already started an immigration process with the INM or COMAR, you can request one. Temporary CURP Certificate; And if you are approved as a resident, the National Institute of Migration will automatically assign you your definitive CURP (Unique Population Registry Code) when it issues your Foreigner's Unique Number. The procedure, in both cases, is gratuitous.
This is one of the most frequent questions we receive at City Laws, especially from newcomers who discover that without a CURP (Unique Population Registry Code), even basic procedures like opening a bank account, signing a contract, or registering with a government agency become complicated. The confusion is understandable: the CURP for foreigners has different forms depending on your immigration status, and not all foreigners are entitled to one. Below, we explain, with the law in hand, what it is, what it's for, who can obtain it, and how to apply for it step by step.
What is the CURP and why does it also apply to foreigners?
The Unique Population Registry Code (CURP) is an 18-character alphanumeric code that the State assigns to each person registered in the National Population Registry, for the purpose of registering and identifying them individually. It is not a privilege reserved for Mexicans: Article 91 of the General Population Law stipulates that the code be assigned to all persons included in the registry, encompassing both nationals and foreigners domiciled or present in the national territory.
The responsible authority is the Ministry of the Interior, through the National Population and Identity Registry (RENAPO). In the case of foreign nationals, the process relies on two immigration authorities: the National Migration Institute (INM), which assigns the CURP when issuing the Unique Foreigner Number, and the Mexican Commission for Refugee Assistance (COMAR), which is delivered along with the proof of processing when the recognition of refugee status is requested.
What is the CURP used for if you are a foreigner?
The CURP serves as your unique identifier with Mexican institutions, and in practice you'll need it for almost any formal procedure in the country. Among the most common uses are:
- Open a bank account or hire services in your name.
- Signing an employment contract and register with the IMSS (Mexican Social Security Institute), when your immigration status allows you to work.
- Register yourself or your children in educational institutions.
- Register with the SAT and carry out tax procedures.
- Accessing services and procedures before public agencies.
One point needs to be clear: the CURP. No It is not an immigration document and does not replace your resident card or passport. It is an administrative identification code. Having a CURP does not, by itself, regularize your stay and does not grant you permission to work if your immigration status does not authorize it.
The two main types: temporary and permanent
Here's the distinction that avoids most confusion. The CURP for foreigners exists in two versions, depending on where you are in the immigration process.
The Temporary CURP Certificate This is for those who have already begun the process of obtaining legal residency through the INM or COMAR but have not yet received a decision. It is issued for a period of up to 180 or 365 calendar days, depending on the case, and remains in effect until the authority issues the final resolution that determines your immigration status.
The final CURP (of a permanent nature) is for those who have already obtained the status of temporary resident or permanent resident. In this case, the INM assigns it automatically when issuing your Unique Foreigner Number (NUE), and that CURP should appear on your resident card.
| Aspect | Temporary CURP Certificate | definitive (permanent) CURP |
|---|---|---|
| For whom? | Foreigner with application initiated before INM or COMAR, without resolution | Temporary or permanent resident already authorized |
| Validity | Up to 180 or 365 calendar days; it lasts until the final resolution. | Permanent |
| How is it obtained? | By proving the start of the process before INM or COMAR | Automatic, upon issuance of the NUE by the INM |
| Does it appear on the resident card? | No (there is no residence yet) | Yeah |
| Cost | Gratuitous | Gratuitous |
Who CANNOT obtain a temporary CURP
Not every foreign national in Mexico is entitled to a temporary CURP (Unique Population Registry Code). It is not issued to tourists. nor to visitors without permission to carry out paid activities. Specifically, the status of stay of Regional Visitor, provided for in section III of article 52 of the Migration Law.
The logic is simple: the temporary CURP is intended for those in the process of regularizing their immigration status, not for those just passing through. Without an application filed with the INM or COMAR, there is no temporary certificate.
If you are a tourist or visitor and need to identify yourself for a specific procedure, it is advisable to review your situation with a immigration lawyer before attempting a procedure that the authority will not authorize, because the fundamental requirement is to have initiated the corresponding immigration procedure.
How to obtain the CURP step by step
The path depends on your situation. These are the three most common scenarios:
- You are already a temporary or permanent resident. You don't need to do anything else: when your resident card is issued, the INM assigns you the NUE and, with it, your permanent CURP. Check that the code appears on your immigration document.
- You started a process with the INM and you still haven't received a resolution. You can request a Temporary CURP Certificate by proving that you have started the process. For permanent assignment to residents, the essential requirement is to have the Our original assigned by the INM.
- You requested refuge from COMAR. COMAR itself gives you the temporary CURP along with the proof of processing of your application.
Once the authority resolves your case favorably and you are recognized as a resident, the CURP changes from temporary to permanent. permanent automatically. Remember: the process is gratuitous in all its forms, so be wary of anyone who charges you to "manage" it.
How to check and validate your CURP online
Whether temporary or permanent, your CURP can be consulted and validated in the official RENAPO website, By entering your password or personal information, you can verify your CURP (Unique Population Registry Code). This is a good practice to do before giving your CURP to a bank, school, or employer to confirm that your information (name, date of birth, country of origin) has been captured correctly. An incorrectly registered CURP can delay subsequent procedures, and correcting it promptly prevents complications.
The 2025 reform: the biometric CURP
He July 16, 2025 A decree reforming the General Population Law to create the biometric CURP: a version that incorporates photography and fingerprints, conceived as a national identification document of universal acceptance throughout the territory, available in physical and digital format.
The reform provides, in its transitional articles, that the Ministry of the Interior will establish a Program for the Integration of biometric data into the National Population Registry, with special attention to girls, boys and adolescents, and that the incorporation of this data will require the prior consent of the headline.
Foreigners should be cautious: the full scope of the biometric CURP requirement for non-residents is not yet entirely clear. For now, the current channel For foreigners, the process remains the same: a Temporary CURP Certificate while their residency application is being processed, and the permanent CURP via NUE once residency is approved. Before assuming a specific biometric requirement, verify its implementation status with the official source.
If your immigration process is complex—changes of status, regularization, refugee status, or cases involving minors—it's worth it. book legal advice to organize documents and avoid delays that later cost time and money.
