Under Mexico's Ley Fintech and the CUIFPEs, an IFPE (electronic payment fund institution) must obtain authorization from CNBV and Banco de México — or file a prior notice (aviso) — before contracting third-party service providers material to its regulated operations. The statutory review period is 25 business days. In practice, resolution takes 6–8 months. Non-compliance carries fines up to 150,000 UMAs (~MXN $16.5M), operations suspension, or license revocation.
Mexico's Ley Fintech (2018) and its secondary regulations impose a specific obligation that catches both fintechs and their technology vendors off guard: before an IFPE can contract certain third-party service providers, it must notify or obtain authorization from CNBV and Banco de México — and getting it wrong carries consequences that range from sanctions to license revocation.
This page explains who is affected, what the process requires, and what it actually costs to get it right — whether you are a fintech looking to onboard a new vendor or a technology company that wants to be contracted by regulated financial institutions in Mexico.
The obligation originates in Article 54 of the Ley Fintech, which authorizes CNBV and Banco de México to establish the specific rules governing third-party contracting by financial technology institutions — and explicitly preserves CNBV's and Banxico's faculty to conduct supervision of contracted vendors at any time.
The operative rules are set out in the CUIFPEs (Disposiciones de Carácter General aplicables a las Instituciones de Fondos de Pago Electrónico), specifically Chapter V, Articles 44 through 55. These provisions were issued jointly by CNBV and Banco de México and are binding on all IFPEs.
This is not a gray area. The obligation exists, it is specific, and both CNBV and Banxico have supervisory authority over the vendors an IFPE contracts — not just over the IFPE itself.
The vendor authorization framework affects two distinct types of organizations:
IFPEs: If you are a licensed electronic payment fund institution in Mexico, you cannot freely contract service providers that are material to your regulated operations. Depending on the type of service and the vendor's profile, you must either obtain full authorization from CNBV and Banco de México, or file a notice (aviso) at least 20 business days before executing the contract. Contracting without the required filing creates direct regulatory exposure — and the General Director of the IFPE is personally responsible for approving vendor contracting under Article 44 of the CUIFPEs.
Technology vendors: If you provide services to a Mexican IFPE, your client is required to file with CNBV and Banxico before they can engage you. This means your service agreement structure, your data access profile, and your technical documentation all directly affect whether — and how quickly — your client can complete the filing. Understanding the process is not optional if you want to close deals with regulated Mexican financial institutions.
The CUIFPEs establish two distinct regulatory regimes, and the determination of which applies to each vendor is not a judgment call — it follows specific criteria set out in Articles 44 and 45 of the CUIFPEs. The consequences of misclassification are significant: treating a vendor that requires full authorization as notice-eligible creates retroactive regulatory exposure for the IFPE and its General Director.
What we can tell you here is this: the determination depends on the nature of the service, the type of data the vendor accesses, the vendor's role in the IFPE's operational continuity, and whether the vendor is a primary or backup provider. A thorough analysis must be carried out on a case-by-case basis, for each vendor and service line, before any filing or contract execution begins.
This analysis is not something that can be resolved by reading a checklist. It is the first thing Legal Paradox® does in every vendor authorization engagement — and it is the step that most firms skip, creating problems that surface months later when CNBV issues observations.
The CUIFPEs establish one relevant exception: authorization is not required when an IFPE contracts another financial entity that is itself subject to substantially similar regulations. This exception is narrower than it appears — it applies to regulated financial entities, not to technology companies or operational vendors that happen to be part of the same corporate group. For intra-group vendor structures where the vendor is not itself a regulated entity, the general authorization framework applies in full.
A full authorization filing for a single vendor involves preparation of a complete regulatory package submitted jointly to CNBV and Banco de México. The package covers the vendor's service scope, operational continuity arrangements, data protection framework, infrastructure description, contractual terms, and governance structure — all mapped to the specific requirements of Article 49 of the CUIFPEs.
Among other things, Article 49 requires that the service agreement between the IFPE and the vendor include specific mandatory clauses — including CNBV and Banxico's right to conduct inspections of the vendor, the vendor's obligation to maintain confidentiality of client information, and provisions for service continuity in case of vendor failure. A contract that does not include these clauses will generate observations regardless of how complete the rest of the filing is.
For vendors domiciled outside Mexico — particularly those operating cloud, data, or processing infrastructure from China, Singapore, the United States, or the European Union — the filing also requires specific treatment of international data transfers under Mexico's LFPDPPP 2025, now administered by the SABG (Secretaría Anticorrupción y Buen Gobierno, which replaced the defunct INAI).
Article 49 of the CUIFPEs establishes a 25-business-day review period for authorization requests. In theory, if CNBV and Banxico do not respond within that window, the authorization is deemed granted (affirmative ficta). In practice, CNBV almost always issues a notice ("oficio de observaciones") before that deadline — requesting additional information, supplementation, or corrections. Each observation round resets the practical timeline.
This is why the total calendar from first filing to resolution typically runs 6–8 months, and why the quality of the initial filing determines how many rounds it takes — not whether rounds occur.
Sanctions at a glance (2026): Fines 30,000–150,000 UMAs (MXN ~$3.5M–$17.6M) · Operations suspension · License revocation (Art. 68-69, Ley Fintech) · Additional up to 320,000 UMAs under LFPDPPP 2025 if personal data is involved · Personal liability for the IFPE's General Director (Art. 44, CUIFPEs).
Contracting a vendor without the required authorization or notice is not a paperwork oversight — it is a regulatory violation with defined consequences under the Ley Fintech:
For context, 150,000 UMAs at the 2026 value represents approximately MXN $17.6 million. These sanctions apply to the IFPE — and the personal responsibility of the General Director established in Article 44 of the CUIFPEs means that individual accountability is also on the table.
Additionally, if the vendor accesses personal data of the IFPE's clients, violations of the NLFPDPPP 2025 can add fines of up to 320,000 UMAs administered by the SABG — a separate and cumulative exposure.
Although a case-by-case analysis must be carried out, the following categories of service providers are typically subject to the vendor authorization framework when contracted by a Mexican IFPE. Whether a specific vendor in each category requires full authorization, or a simple notice, or an exception exists, depends on the analysis described above — category alone does not determine treatment.

These are not hypothetical risks. They are the patterns Legal Paradox® sees consistently across IFPE vendor authorization processes — and the ones that generate the most observation rounds.
For IFPEs:
For technology vendors:
IFPEs operating within a corporate group — where the vendor and the IFPE are entities within the same group — face specific requirements that are not automatically resolved by the group relationship. The CUIFPEs do not provide a blanket intra-group exemption for technology or operational vendors. Each vendor must be analyzed individually, and the filing strategy must be coordinated across the group to ensure consistency — because CNBV evaluates the group's vendor governance as a whole, and inconsistencies across filings generate observations that have nothing to do with any individual vendor's profile.
Direct connection to SPEI (Mexico's real-time payment system) involves a separate authorization process before Banco de México — not CNBV — with its own regulatory framework and technical requirements. This process is distinct from the typical vendor authorization framework described on this page.

Does every vendor an IFPE contracts require CNBV authorization?
No. The applicable regulation distinguishes between vendors that require full authorization and vendors that require only a notice filed 20 business days before contracting. Some vendors may be exempt. The determination depends on specific criteria established in the CUIFPEs and must be made case-by-case — it cannot be resolved by applying a general category rule.
What is the statutory timeline for CNBV to respond to an authorization request?
The CUIFPEs establish a 25-business-day review period. If CNBV and Banxico do not respond within that window, the authorization is deemed granted (affirmative ficta). In practice, CNBV almost always issues observations before that deadline, which is why the total calendar from first filing to resolution runs 6–8 months.
Can we contract the vendor while the filing is in process?
This is a risk management decision that depends on the specific circumstances. Contracting before resolution creates regulatory exposure under the Ley Fintech, including potential sanctions and personal liability for the IFPE's General Director. We recommend resolving the filing treatment determination and initiating the filing before executing the contract.
What happens if we contracted a vendor without filing?
This creates retroactive regulatory exposure. Sanctions under the Ley Fintech range from fines of 30,000–150,000 UMAs to suspension of operations or license revocation. The appropriate response depends on the specific situation. Legal Paradox® can assess the exposure and recommend a remediation strategy.
We are a technology vendor. Is this our problem or our client's?
Legally, the obligation falls on the IFPE. In practice, your service agreement structure, technical documentation, and data access profile directly determine whether your client can complete the filing — and how many observation rounds it takes. Vendors that understand the process and prepare for it close deals faster.
Is there an exemption for intra-group vendors?
The CUIFPEs provide a limited exemption for financial entities that are themselves subject to substantially similar regulations — not a blanket intra-group exemption. Technology or operational vendors within the same corporate group that are not independently regulated are subject to the general authorization framework.
Does SPEI direct connection require this process?
SPEI direct connection is a separate authorization process before Banco de México, not CNBV, with its own framework and requirements. It is handled as a distinct engagement.
Is this process the same for IFCs (crowdfunding platforms)?
The framework is similar but governed by the secondary regulation applicable to IFCs rather than IFPEs. The specific document requirements and review criteria differ. Legal Paradox® handles both.
What are the sanctions for non-compliance?
Sanctions under the Ley Fintech include fines of 30,000–150,000 UMAs (approximately MXN ~$3.5M–$17.6M at 2026 values), suspension of operations, and license revocation. If the vendor accesses personal data, additional fines of up to 320,000 UMAs may apply under the NLFPDPPP 2025.
