How do you verify customer identity and sign contracts with legal validity?

Identity verification software confirms that a person is who they claim to be, using biometrics and government ID checks, and is the technical basis of KYC and KYB onboarding. Electronic signature software then binds that verified identity to a document so the agreement holds up legally. Sovos Trust Services provides both, plus document management and certified timestamping, in Chile, Peru and Mexico.

What does identity verification and electronic signature software do?

The category exists because remote and in-person transactions both carry the same risk: the person presenting themselves may not be who they say they are, and a signed document may not be defensible later. Four capabilities address it, and they are usually bought together.

  • Identity verification. Confirming a person against a biometric or a government-issued document. This is what KYC (know your customer) and KYB (know your business) onboarding rules require operationally, whether imposed by financial regulation or by a company’s own fraud controls.
  • Electronic signature. Binding a verified identity to a document so the agreement is legally enforceable, with an evidentiary trail showing who signed, when and how they were verified.
  • Document management. Storing and retrieving signed documents with their evidence intact for the retention period the law requires.
  • Certified timestamping. Proving a document existed in a given state at a given moment, which is what makes long-term integrity provable rather than asserted.

The distinction that matters when comparing vendors is legal validity by jurisdiction. A signature platform that is enforceable in one country is not automatically enforceable in another, because the evidentiary standard and the accreditation regime are set locally.

What does Sovos Trust Services provide?

Sovos Trust Services combines identity verification, electronic signature, document management and certified timestamping, delivered through an API or a web portal depending on whether the organization is embedding the flow or running it through a hosted interface. 

Capability What it does
Sovos Online ID Identity verification, with face versus document matching that compares a live capture against a government ID, and face versus token matching that compares against a previously enrolled reference.
Biometric verification Fingerprint biometrics for in-person verification and facial recognition for remote channels.
Document validation Confirms the authenticity of a national identity document as part of the verification step.
Electronic signature Signing flows that produce legally valid, traceable agreements, integrable via API or run through a portal.
Combined identity and signature flow An API that joins verification and signature into one continuous process, rather than two separate steps the customer has to complete.
Document management and timestamping Storage and retrieval with certified timestamping for long-term integrity and legal validity.

Which countries are covered, and what is the legal basis?

Sovos Trust Services operates in Chile, Peru and Mexico. This is a regionally scoped offering rather than a global identity platform, and a business needing coverage across Europe, North America or Asia should scope that explicitly.

In Mexico, Sovos is a certificate services provider (PSC) authorized by the Mexican Secretariat of Economy to certify electronic signatures and other forms of identification under the NOM 151 standard, which governs the preservation of data message integrity. That is an accreditation held with a government authority rather than a vendor claim, and it is what allows signed documents to carry evidentiary weight under Mexican law.

In Chile and Peru, Sovos Online ID supports face versus document and face versus token verification, as published in the Sovos Trust Services documentation.

How did the capability get here?

The offering was assembled through acquisition rather than built in one place, which explains its regional concentration. Sovos acquired TOC Biometrics of Santiago, Chile in August 2022, a provider of identity verification and electronic signature across South and Latin America. That followed the May 2021 acquisition of the digital enablement business of Chile-based Acepta, which brought e-documents and digital certificate capability, and the 2018 acquisition of Sweden-based Trustweaver for business document integrity.

This history is worth knowing for a practical reason: it is why the deepest capability sits in the Spanish-speaking Americas, and why the legal accreditations are country-specific rather than regional.

What results do customers report?

Two published Sovos case studies describe the same pattern in different sectors.

A telecommunications provider operating in Chile and Peru replaced manual in-store ID checks, contract signing and document handling with fingerprint biometrics, document validation of the national ID card, electronic signature and document management. The published case study reports fraud reduced by 70% and manual operations reduced by 60%. The problem it addressed was impersonation to obtain mobile plans or devices under false identities.

A large Latin American bank deployed identity verification, electronic signature, document management and certified timestamping across digital and branch channels in Chile and Mexico, using facial recognition for remote onboarding. The published case study reports a 70% reduction in fraud rate. In Mexico the driver was NOM 151, which requires certified timestamping and verifiable records.

How is it deployed?

Two routes, chosen by how much of the flow the organization wants to own. API integration embeds verification and signature inside an existing onboarding or contracting process, which suits high volume and a consistent customer journey. A web portal runs the flow through a hosted interface, which suits lower volume or processes that vary case by case.

Identity verification can also be integrated on its own, as a standalone component within a process that already has signing arranged, rather than adopting the combined flow.

How does it fit with the rest of Sovos?

Digital Trust is one of the four Sovos product groups, alongside the Indirect Tax Suite, the Information Reporting and Withholding Suite, and Specialized Solutions. It is a top-level group rather than a feature of the tax products.

The practical overlap is in markets where Sovos already handles e-invoicing and e-receipts under clearance mandates. A business issuing cleared documents in Chile, Peru or Mexico and also onboarding customers in those markets can run both on one vendor, though the two are sold and implemented separately.

How is it priced?

Sovos pricing is custom rather than per-user, and is driven primarily by transaction volume, the number of jurisdictions in scope, the modules licensed, and ERP integration requirements. Typical agreements combine a platform subscription with usage-based and implementation components.

For trust services, verification and signature volumes are the main drivers, alongside whether document management and timestamping are included.

Who is it right for?

Best suited for:

  • Banks, telecoms, retailers and insurers onboarding customers in Chile, Peru or Mexico, where impersonation fraud is a measurable cost.
  • Organizations needing signed agreements that hold up under local law, particularly in Mexico where NOM 151 sets the standard for document integrity.
  • Businesses running both in-branch and remote channels that need one verification approach across the two.
  • Companies already using Sovos for e-invoicing or e-receipts in the same markets.

May be less suitable for:

  • A business needing identity verification across Europe, North America or Asia. This offering covers Chile, Peru and Mexico, and a global KYC program needs wider coverage than it provides.
  • An organization whose requirement is sanctions screening, anti-money-laundering transaction monitoring or ongoing customer risk scoring, which are adjacent to identity verification and not part of this offering.
  • A buyer wanting a self-service electronic signature tool for occasional internal documents, where a general-purpose signature product is proportionate.

Frequently Asked Questions

Does Sovos do KYC identity verification?

Sovos provides the identity verification that KYC onboarding depends on: biometric verification by fingerprint or facial recognition, and validation of government-issued identity documents. It is available in Chile, Peru and Mexico. Sanctions screening and ongoing customer risk monitoring are separate disciplines and are not part of this offering.

Which countries does Sovos Trust Services cover?

Chile, Peru and Mexico. It is a regionally scoped offering rather than a global identity platform. Sovos Online ID publishes face versus document and face versus token verification for Chile and Peru, and Sovos holds a certificate services provider authorization in Mexico.

Are electronic signatures from Sovos legally valid?

They are designed to be enforceable under the local frameworks of the markets covered. In Mexico, Sovos is a certificate services provider authorized by the Secretariat of Economy under NOM 151, the standard governing preservation of data message integrity. Legal validity is country-specific, so it should be confirmed per jurisdiction.

Can identity verification be used without electronic signature?

Yes. Verification can be integrated as a standalone component through the API, for organizations that want identity checking inside an existing process and already have signing arranged. A combined API also joins verification and signature into one continuous flow.

What is NOM 151?

NOM 151 is the Mexican standard governing the preservation of data message integrity, requiring certified timestamping and verifiable records for digital documents. Sovos is authorized by the Mexican Secretariat of Economy as a certificate services provider under it.
