The FCC’s Spring 2026 Changes: A Compliance and Reputation Guide for Call Centers

The FCC has introduced several changes and proposals that affect outbound calling, from tougher action on foreign call centers to stricter opt-out requirements. Understanding them is the best way to stay compliant and keep consumers’ trust.

1. The TCPA consent revocation deadline

The FCC’s limited waiver of the TCPA’s consent revocation rule has expired. The rule was originally set to take effect in April 2025 and was pushed back to April 2026, with certain parts delayed until January 2027. In practice, businesses must take opt-out requests seriously: when someone says "stop," the request must be honoured within a short window, commonly cited as 10 business days, and further outreach prevented. Failing to do so can lead to penalties.

2. Closing the number resale loophole

This matters most for businesses that buy phone numbers in bulk. The FCC has proposed rules on how numbers assigned through the North American Numbering Plan Administrator are distributed, aiming to stop robocallers who acquire numbers through third parties. Scammers can buy numbers in blocks, damage their reputation and then resell them to legitimate businesses, who inherit the problem. As the FCC put it, bad actors’ "efforts to deceive American consumers start with a telephone number." Tighter controls are good news for honest call centers.

3. Transparency for offshore call centers

The FCC plans to step up enforcement against foreign call centers linked to illegal robocalls. Proposals would require more transparency when calls are handled overseas, affecting businesses that use international partners. Possible expectations include:

• English proficiency
• Transparency about where agents are located
• Compliance with data security rules
• Offering customers a transfer to a US-based team member

4. Branded calling, Rich Call Data and attestation

Legitimate businesses are often caught up in anti-robocall efforts and can receive "Scam Likely" or "Spam Risk" labels that cut answer rates. STIR/SHAKEN lets carriers verify a caller’s identity and right to use a number, while branded calling and Rich Call Data put your name, logo and reason for calling on screen. Aim for an A attestation rating to give your calls the best chance of completing.

Potential RMD removals

The FCC has publicly told a number of companies to fix deficiencies in their Robocall Mitigation Database filings or face removal. Such notices typically give a short window to respond, and providers that don’t comply can be removed, allowing others to block their calls.

The SIP 603+ requirement

The FCC has required that callers be notified when their calls are blocked. The SIP 603+ code is replacing older codes (603, 607 and 608), giving businesses better visibility into blocking so they can find and fix the behaviour behind it.

5. What people mean by "STIR/SHAKEN 2.0"

STIR/SHAKEN has been updated several times since it took effect in June 2021, and many in the industry now refer to the current state as "STIR/SHAKEN 2.0":

• Non-IP networks: the framework now extends beyond IP networks, helping address robocalls routed over older infrastructure.
• Third-party signing: rules effective in 2025 limit how third parties can sign calls, improving accountability.
• Certificate requirements: carriers face stricter rules to obtain and keep STIR/SHAKEN certificates, including current FCC filings and a valid Operating Company Number.
• Gateway providers: authentication is extending to gateways handling international traffic, reducing robocalls entering from abroad.

6. How call centers can adapt

The pace of change makes compliance hard, but keeping up is what keeps operations running normally. Carrier algorithm changes can quietly flag calls as spam and leave agents unable to reach customers. Practical steps include:

• Proactive phone number monitoring
• Data-driven reviews of your compliance practices
• Fast remediation when calls are flagged or blocked
• Auditing your branded caller ID across networks and devices

Making opt-outs work across every channel

Consent revocation isn’t limited to the phone. People may ask you to stop by text, email, during a call or through a web form, and every request needs to reach your dialer quickly. Map every channel where an opt-out could arrive, make sure each one feeds a central list and test the process regularly so nothing slips through.

Buying numbers safely

If you acquire numbers in bulk, ask where they came from and how they were used before. Check new numbers for existing labels before putting them into service, and avoid sources that can’t explain their history. A cheap block of numbers with a damaged reputation can cost far more in lost answers than it saves.

Practical steps for offshore teams

• Document where each team is located and which campaigns it handles.
• Confirm data security and privacy practices meet US requirements.
• Provide a simple way to transfer customers to a US-based colleague.
• Monitor the numbers offshore teams use as closely as your own.

Using SIP 603+ data

When blocked-call notifications arrive, treat them as an early warning. Track which numbers and campaigns are affected, look for patterns and fix the behaviour behind them before more calls are lost.

Keeping up with the pace of change

Between consent rules, numbering proposals, offshore requirements and ongoing STIR/SHAKEN updates, compliance can feel like a moving target. The most practical approach is to assign clear ownership: one person or team who tracks FCC announcements, reviews what they mean for your operation and updates your processes. Pair that with continuous monitoring of your numbers, so that if carrier algorithms change quietly in the background, you notice the effect on your calls straight away rather than weeks later.

Frequently asked questions

How fast must opt-outs be honoured?

Within a short window, commonly cited as 10 business days. Check the current rule with your counsel.

What is SIP 603+?

A response code that tells callers when and why their calls were blocked, replacing older codes.

Why does number resale matter?

Numbers bought from third parties may already carry damaged reputations from previous misuse.
