That is where identity verification becomes operationally important. In a STIR/SHAKEN environment the identity of the caller is connected to certificates, attestation, telephone-number authorization and verification. A weakness in any of these areas can affect both authentication reliability and a provider's ability to demonstrate that its processes meet applicable requirements.
Note: Regulatory requirements vary by jurisdiction and provider role. The discussion below focuses primarily on the U.S. STIR/SHAKEN and robocall-mitigation framework and should not be treated as legal advice.
1. Why Identity Verification Has Become a Compliance Requirement
Compliance Starts With Knowing Who Is Behind the Call
STIR/SHAKEN uses public-key cryptography to allow providers to authenticate caller identity. The originating provider evaluates the caller and calling number then creates a digitally signed PASSporT. The terminating provider can use the associated certificate to verify that information. (TransNexus)
This creates a direct connection between identity verification and regulatory compliance.
Consider a telecom provider that allows a business customer to originate calls using a number. If the provider has no reliable process for establishing the customer's identity or authorization to use that number then its authentication decisions become difficult to defend operationally.
Identity verification therefore acts like the foundation of a compliance structure. The certificate may prove that a trusted provider signed the call but the provider still needs appropriate processes behind the identity and number information being asserted.
The Regulatory Environment Is Becoming More Operational
The FCC's rules require voice service providers to maintain robocall mitigation programs and file certifications through the Robocall Mitigation Database. The FCC has also required providers to describe their mitigation measures and respond to traceback requests within 24 hours. (FCC Docs)
In 2026 the FCC announced annual RMD recertification requirements. It also noted that inaccurate RMD information can result in a $10,000 base forfeiture amount for each violation while failure to update changed information within 10 business days can carry a $1,000 base forfeiture amount under the applicable rules. (FCC Docs)
The practical lesson is important: compliance information needs to remain accurate after the initial filing.
2. How STIR/SHAKEN Connects Identity With Compliance
Certificates Establish Cryptographic Trust
A STIR/SHAKEN certificate connects a service provider's identity with a public key. During verification the receiving provider can validate the certificate and use the public key to check the call signature. (TransNexus)
This creates several connected layers:
Customer identity → Number authorization → Attestation → Call signature → Certificate → Verification
If the first layers are inaccurate then strong cryptography cannot correct the underlying identity information.
Attestation Reflects the Provider's Knowledge
Attestation is particularly important because it communicates what the originating provider knows about the caller and the caller's right to use the telephone number.
Twilio describes A attestation as applying when the provider knows the caller and can establish the caller's right to use the number. B applies when the customer is known but number-use authorization cannot be established to the same level while C applies when the requirements for A or B are not met. (Twilio)
This makes identity verification more than a technical authentication exercise.
For example a provider may know a reseller as a legitimate customer but have incomplete evidence about whether a particular number belongs to that reseller. The provider's authentication decision needs to reflect that distinction.
3. Building Identity Verification Into Customer Onboarding
Verification Should Begin Before the First Call
One of the most effective ways to support compliance is to make identity verification part of customer onboarding rather than a separate activity performed later.
A telecom provider can establish a workflow such as:
Identify the business or customer
Validate relevant business information
Establish the customer relationship
Associate telephone numbers with the appropriate identity
Determine authorization to use those numbers
Apply the appropriate authentication policy
Maintain records as the relationship changes
This creates a traceable connection between the customer and the calls they originate.
Competitors Illustrate Different Approaches
Twilio's Trust Hub provides a centralized model where business identity information is managed through compliance profiles. Its SHAKEN/STIR onboarding process associates phone numbers with approved business profiles and Trust Products. (Twilio)
This demonstrates how identity verification can be incorporated directly into customer provisioning.
For a different model, Peeringhub focuses more specifically on the STIR/SHAKEN trust infrastructure layer. Its platform provides certificate enrollment and management along with Identity Header parsing, certificate inspection, OCN lookup, STI-CR hosting and developer automation. (Peering Hub)
The distinction matters. A communications platform may integrate identity verification into a broader customer-management environment while a dedicated STIR/SHAKEN infrastructure provider can focus on the certificate and identity mechanisms supporting voice authentication.
4. Certificate Management Is Part of Compliance
A Valid Identity Needs a Valid Credential
Identity verification does not end when a provider confirms a customer's information.
The cryptographic credentials supporting that identity must remain operational.
STIR/SHAKEN certificate management includes obtaining certificates from an authorized CA, protecting private keys, publishing certificates for verification and managing renewal or revocation. TransNexus describes the certificate lifecycle as an essential part of maintaining the STIR/SHAKEN trust model. (TransNexus)
Think of a certificate as a professional license. Establishing the identity of the organization is important but an expired license cannot continue to provide valid evidence indefinitely.
Automation Makes Lifecycle Management More Consistent
Peeringhub provides certificate management through its web interface, APIs and Python tooling. Its platform is designed around certificate issuance, management and automation for STIR/SHAKEN environments. (Peering Hub)
This can help providers connect certificate operations with existing infrastructure.
Instead of relying on spreadsheets and calendar reminders, operators can build automated processes around:
Certificate issuance
Renewal
Rotation
Revocation
Certificate inspection
Public certificate hosting
Status monitoring
The objective is not simply convenience. It is maintaining a consistent trust infrastructure that supports ongoing authentication.
5. Identity Verification Helps Create an Audit Trail
Compliance Requires More Than a Policy Document
A written policy saying that customers are verified is different from being able to demonstrate how verification actually occurred.
For telecom operators an effective compliance process should be supported by operational records showing relevant identity and authorization decisions.
For example:
Customer A → Verified business identity → Authorized number range → Authentication policy → Signed calls
If a question later arises about traffic from Customer A the provider has a logical chain connecting the customer relationship to the authentication decision.
This becomes particularly valuable when handling traceback requests.
Traceability Connects Compliance With Operations
The FCC requires providers subject to its robocall mitigation rules to commit to responding to traceback requests within 24 hours. (FCC Docs)
That requirement highlights why identity data needs to be accessible and organized.
If a provider cannot quickly determine which customer, number or upstream relationship was associated with particular traffic then the problem is not simply administrative. It becomes an operational limitation.
Identity verification can therefore support:
Customer traceability
Number ownership records
Authentication investigations
Traffic attribution
Compliance documentation
Incident response
A good analogy is an accounting system. The value is not merely recording transactions but being able to trace a transaction back to its source when someone asks how a number was reached.
6. Continuous Verification Matters as Telecom Relationships Change
Customer Information Does Not Stay Static
Telecom environments change constantly.
Customers add numbers. Resellers change downstream relationships. Numbers move between accounts. New routes are introduced and certificates are renewed.
A verification process that is accurate on day one can become inaccurate later if the underlying records are not maintained.
This is especially relevant because the FCC's RMD framework requires providers to ensure their submitted information remains accurate and to update changed information within the applicable timeframe. (FCC Docs)
Continuous Controls Reduce Compliance Gaps
A practical identity-management cycle looks like:
Verify → Associate → Authenticate → Monitor → Revalidate → Update
This does not mean every customer needs to be manually reverified every day. Instead it means identity controls should respond when meaningful changes occur.
For example if a customer receives a new number range the provider should not automatically assume that the authorization record for an older number range applies to the new range.
This principle is increasingly important as telecom providers support resellers, enterprises, call centers and other complex customer structures.
7. Choosing the Right Identity and Authentication Infrastructure
Compliance Architecture Should Match the Operating Model
Telecom operators have different requirements depending on whether they are carriers, service providers, intermediaries, communications platforms or technology providers.
The market reflects these differences.
Peeringhub provides a focused STIR/SHAKEN certificate authority and identity infrastructure model. Its current platform includes certificate enrollment and management, delegated signing capabilities, attestation controls, Identity Header parsing, Certificate Inspector, OCN Lookup, STI-CR hosting and developer APIs. (Peering Hub)
TransNexus offers a broader STIR/SHAKEN platform covering authentication, verification, secure key management, certificate management and certificate repository functions. (TransNexus)
Twilio integrates SHAKEN/STIR with customer identity and compliance workflows through Trust Hub. Its onboarding process uses business profiles, telephone-number associations and SHAKEN/STIR Trust Products. (Twilio)
These models should not be treated as interchangeable. The relevant question for an operator is how identity verification, certificate management and authentication infrastructure fit into its existing network and compliance processes.
Build Around Evidence Not Just Configuration
A strong compliance architecture should make it possible to answer practical questions:
Who is the customer?
Who is authorized to use the number?
What attestation decision was applied?
Which certificate signed the call?
Where is the certificate published?
When was the credential issued or renewed?
Which system performed the authentication?
Can the relevant information be retrieved during an investigation?
If these questions can be answered efficiently then compliance becomes much more closely integrated with network operations.
Conclusion: Identity Verification Is Becoming a Core Telecom Control
Regulatory compliance in voice communications is increasingly connected to the quality of identity information behind every authenticated call.
STIR/SHAKEN provides the cryptographic framework but reliable compliance depends on the operational processes surrounding it. Customer identity needs to be verified. Telephone-number authorization needs to be understood. Attestation needs to reflect available evidence. Certificates need to remain valid and accessible. Records need to stay accurate as customer and network relationships change.
The FCC's current framework also demonstrates why continuous governance matters. Providers are expected to maintain robocall mitigation programs, certify relevant information and keep their regulatory records accurate. (FCC Docs)
For telecom operators this means identity verification should not sit separately from network operations. It should connect customer onboarding, number management, authentication, certificate lifecycle management and compliance reporting into one traceable workflow.
Peeringhub provides the STIR/SHAKEN infrastructure to support that workflow through certificate authority services, Identity Header analysis, certificate inspection, STI-CR hosting, OCN lookup and developer automation. (Peering Hub)
The goal is straightforward: make trusted caller identity measurable, manageable and defensible across the communication lifecycle.
