KYCC in Telecom 2025: Traceability, Compliance & Customer Protection

KYCC (Know Your Customer's Customer) is gaining prominence in U.S. telecommunications amid increasing regulation and fraud risks. This practice extends traditional KYC protocols to cover not just your direct customers, but their customers too—providing full transparency through complex telecom chains.

For example, when a number is issued by the FCC, handed to a Tier 1 carrier like AT&T, routed through a CPaaS like Twilio, and finally assigned to a Boost Mobile user, KYCC ensures every handoff is known. This approach supports FCC rules, STIR/SHAKEN frameworks, and TRACED Act enforcement—helping telecom providers prevent spoofing, robocalls, and traceability gaps.

Video Summary: In this 2m32s video, TSG Global breaks down how KYCC enhances traceability, reduces spam, and ensures compliance with STIR/SHAKEN and TRACED Act mandates.

There’s another level to KYC which comes into knowing your customer’s customer. It’s actually an extension to that acronym. Like we didn’t have enough letters already in it, but now it’s KYCC or CCC or whatever. It depends how many customers are in that chain of custody. And in telecom, as you’ll understand, by the time you get your phone number assigned to you, there are many other stakeholders in that chain of custody before you get that assigned service level.

So if you take your cell phone, for example, there’s the government that assigns the numbers to the phone companies, then there are the phone companies, then there might be resellers of the phone company. So if you think about your cellular service being on Boost Mobile, for example, it first comes through the government. That number is leased to, let’s say, Verizon Wireless or AT&T Wireless and then rolls down to a mobile network operator that resells one of those other networks. In other words, uses the same towers and all that. And that could be somebody like Boost Mobile or Cricket or some name like that.

And when you think about your phone number now, that’s traversing multiple organizations before it gets assigned to you. So knowing your customer’s customer just basically means knowing every level from the assignment of the phone number all the way down to the end user.

⏱️ Timeline

Q1 2025

FCC issues new KYCC mandates for telecom

Q2 2025

Carriers begin enforcing stricter number traceability

Q3 2025

KYCC audit tools deployed by CPaaS platforms

Q4 2025

⚠️ Important Considerations

Risk 1: Chain Breaks:

Missing a handoff could result in regulatory penalties

Risk 2: Reseller Misuse:

Without KYCC, an enterprise could be penalized for downstream fraud

Risk 3: Data Gaps:

Non-integrated platforms may struggle to provide real-time lineage visibility

❓ FAQ

KYCC helps service providers trace the full chain of custody for phone numbers. It extends KYC protocols into downstream customer territory.

STIR/SHAKEN requires validated caller identity. KYCC confirms if a number belongs to a direct customer or is rented further downstream.

Because robocalls and carrier enforcement are increasing, knowing your customer's customer is now essential for compliance and trust.

Carriers, CPaaS platforms, MVNOs, and enterprises all gain accountability and reduced fraud risk with clear number lineage.

📋 Step-by-Step Guide

Step 1: Audit Number Assignments:

Document all current number holders across partners

Step 2: Map Reseller Chains:

Identify all downstream customer relationships

Step 3: Implement Tracking:

Use APIs or ledgers to log number transitions in real time

Step 4: Validate Chain Ownership:

Require proof of customer relationships for reassignment

Step 5: Prepare for Audits:

Ensure traceability reports meet FCC and STIR/SHAKEN requirements
