Know Your Customer (KYC), sometimes known as Know Your Business (KYB), is getting more attention across the telecom industry, but the term itself is being broadly used to mean very different levels of rigor, creating real gaps in accountability.
For some organizations, KYC/KYB refers to basic data collection. For others, it is a robust process designed to establish verified identity and determine whether an entity is fit to communicate with consumers.
That distinction matters. In a network where fraud thrives on anonymity, collecting information is not the same as verifying identity.
For organizations originating voice or messaging traffic, data collection alone is no longer sufficient. This article is for providers and enterprises who originate voice or messaging traffic and need to move beyond data collection to verified identity in order to reduce fraud, improve trust, and meet evolving regulatory expectations.
In telecom, Know Your Customer is the process of verifying the identity of entities using communication networks. However, not all KYC is the same.
Basic KYC confirms that required information has been submitted whereas rigorous KYC verifies that an entity is real, legitimate, and suitable to communicate with consumers, going beyond data collection to establish trusted identity and accountability.
Regulators like the FCC and FTC increasingly expect originating service providers (OSPs) to verify identity rather than rely on data collection alone. As a result, KYC cannot be treated as a one-and-done transaction.
It is important to clarify how KYC and KYB apply within communications networks:
“KYC” and “KYB” are often used interchangeably. In telecom, this means verifying the business behind the call or message and determining whether it is fit to communicate.
In robocall mitigation and large-scale outbound communications, Know Your Business (KYB) is particularly relevant as higher volumes are generally sent by organizations than between individuals. In telecom, this means verifying the businesses behind the call or message and whether it is fit to communicate.
In practice, KYC in telecom falls into two distinct approaches based on level of rigor and whether suitability is evaluated.
Basic vetting is the most common interpretation of KYC today, and also the most minimal. It focuses on collecting required business information (name, address, contact details, etc.) and verifying that the required fields have been submitted and formatted correctly. In this model, the presence of an address, point of contact, or document is considered sufficient. If the data exists, the requirement is treated as complete.
For example:
For example, a submitted address may lead to a non-operational location, and a listed executive may not be a real person. Under basic vetting, the submission can still pass because the fields were completed.
Basic vetting confirms data submission, not truth, legitimacy, or accountability. It cannot prevent impersonation or establish trust in the network.
A more complete approach to KYC focuses on establishing verified identity and responsible use. Rigorous KYC is about confirming not just who an entity claims to be, but whether that entity should be permitted to interact via the network.
Identity verification confirms that the entity behind the request is real, legitimate, and accurately represented by the information provided. Unlike basic vetting, identity verification evaluates authenticity.
This step answers core questions such as:
Suitability assessment evaluates whether the verified entity is fit for the communications activity it intends to perform.
In telecom and messaging, this means determining:
This is the difference between submitted information and verified reality:
Robust KYC enables the network to make informed administrative decisions before traffic is allowed. Suitability assessment evaluates information quality, relevance, and trustworthiness, not just its existence. By combining identity verification with suitability assessment, communications providers can confidently associate traffic with responsible entities, enforce accountability, and reduce fraud and impersonation at scale.
One of the most critical and often overlooked elements in KYC is suitability.
In telecom, suitability determines whether the information submitted by an entity meets the criteria required to grant access to communicate based on legitimacy, use case, and risk.
In a minimal KYC application, once an entity can be shown to exist, the assumption is that it should be allowed to communicate. That assumption creates risk.
Identity alone does not establish trust. Suitability determines whether the entity under evaluation should be granted access to communicate.
Effective KYC in communications follows a clear sequence:
Only after these steps can a trusted identity be established. Without suitability, KYC becomes a procedural exercise that confirms existence, rather than a meaningful safeguard that proves responsibility.
When implemented correctly, rigorous KYC delivers clear benefits across the communications ecosystem.
Rigorous KYC that includes suitability:
When identity is not rigorously established:
The result is a system where fraud persists, consumer trust continues to erode, and legitimate communications fail to reach consumers. Basic vetting cannot address these challenges. Only verified identity, grounded in robust KYC and suitability, can.
Identity is not static. Ownership, domains, and business attributes change over time. Effective KYC treats identity as a living profile that requires ongoing monitoring, not a one-time check at onboarding.
As regulators focus more directly on identity in communications, clarity on what KYC actually means is critical.
The FCC has tightened its enforcement posture around illegal robocalling and directly cited in their 2026 Spring Agenda that,
"The Commission will vote on a proposal to strengthen our “Know‑Your‑Customer” rules for originating providers, closing gaps that have allowed too many illegal calls to enter the network. By seeking comment on clearer, more rigorous customer‑verification standards, this proposal helps stop illegal calls before they ever reach the American people.”
At the same time, the state Attorneys General have warned voice service providers that they may be held responsible when fraudulent traffic originates from entities they have onboarded, elevating expectations around verification and oversight.
In March and April of 2026, Numeracle met with FCC leadership, including Chairman Carr, additional Commissioners, and FCC Bureaus to underscore the importance of identity credential verification over simple data collection, reinforcing via a subsequent ex parte filing that true KYC in telecom requires validation, not just submission. As we highlighted in that discussion,
“The industry cannot rely on data collection or self‑asserted information as a proxy for identity. The integrity of the voice channel depends on verifying that an entity is who it claims to be.”
— Keith Buell, General Counsel & Head of Global Public Policy; Numeracle
KYC, when implemented with rigor, is more than a compliance checkbox. It is the foundation for verified identity in communications.
As telecom evolves, the distinction between basic vetting and true identity verification will define how trust is established, how fraud is prevented, and how legitimate businesses connect with consumers. Systems that rely on data collection alone will continue to face fraud and declining trust.

In telecom, these terms represent very different levels of rigor.
True KYC in telecom requires all three steps, with suitability being the critical factor that transforms identity verification into meaningful trust.
Basic KYC fails because it does not verify whether the information provided is real or appropriate for communications activity.
A business can submit an address, a name, and supporting documents, and still operate from a non‑business location, misrepresent key individuals, or use caller identity in ways inconsistent with its stated purpose.
Without identity verification and suitability assessment, bad actors can easily pass intake checks and impersonate trusted brands. Because downstream anti-spoofing controls are limited, preventing consumer harm, mislabeled calls, blocked legitimate traffic, and increased regulatory risk requires stopping unverified entities before they are allowed onto the network, not after form completion.
Traditional KYC programs often focus on collecting information during onboarding and treat the process as complete once access is granted.
KYCaaS is different because it:
By using KYCaaS, telecom providers and platforms can meet regulatory expectations for identity verification, reduce fraud risk, and establish trusted caller identity without building and maintaining complex identity infrastructure internally.
