Key Takeaways
Before diving into the details, keep these core points in mind about branded caller ID compliance in 2026.
- Branded caller ID compliance rests on three layers: legal registration, STIR/SHAKEN A-level attestation, and carrier-specific verification with AT&T, Verizon, and T-Mobile.
- Non-compliance can trigger carrier blocking, spam labeling, and potential TCPA exposure of up to $1,500 per call.
- Display names must match registered trademarks, stay within 15 to 35 characters, and exclude URLs, PII, or restricted content.
- iOS 26 call screening and Android verified calls make A-level attested branded caller ID critical for sustaining answer rates.
- Plura AI is an FCC-licensed carrier that issues branded caller ID directly at the carrier level with built-in STIR/SHAKEN authentication, so you can see how it works with AI-powered dialing in a live environment.
What Branded Caller ID Is And Why Compliance Matters
Branded caller ID, also called branded calling, shows a verified business name and, on enhanced tiers, a logo and call reason on the recipient’s screen before they answer. It replaces the legacy CNAM system, which relies on inconsistent database lookups that often display generic labels such as “WIRELESS CALLER” or “UNKNOWN.”
Compliance directly affects whether calls reach customers. Carriers and analytics engines label unauthenticated or poorly attested calls as “Spam Likely” or “Scam Risk.” 95% of recipients decline calls labeled “Spam Likely” without answering.3 The regulatory landscape includes:
- The TRACED Act (P.L. 116-105), which required STIR/SHAKEN implementation and expanded FCC enforcement authority against illegal robocalls2
- FCC rules at 47 CFR 64.6301 and 64.6302 that mandate caller ID authentication across IP networks2
- The FCC’s 2025 third-party authentication order (WC Docket No. 17-97), which states that providers must make attestation decisions themselves even when outsourcing signing
Non-compliance can result in carrier blocking, spam labeling, and financial exposure. TCPA violations carry statutory damages of $500 to $1,500 per unsolicited call, with class action settlements averaging $6.6M in 2023.3

Legal And Registration Requirements For Branded Caller ID
Carriers require a set of legal and business checks before they will brand outbound calls. These baseline requirements apply regardless of carrier program or provider.
Business Entity Verification. The organization must be legally registered to operate in the United States. Carriers and the FCC rely on this verification to reduce spoofing risk. Required documentation typically includes legal business name, EIN or DUNS number, business address, business type, and evidence of good standing.
Trademark Validation. The display name must match the registered business name or a registered trademark. Carriers validate trademarks through the USPTO database. Display names are limited to 15 to 35 characters depending on the carrier and tier and must exclude URLs, PII, special characters, and restricted content.
Verifiable Online Presence. The official website must publish a clear privacy policy and terms of service. This gives carriers an additional signal that the submitting organization operates as a legitimate business.
Authorized Representative. A signed Letter of Authorization (LoA) from an owner, executive, or authorized officer confirms legal authority to use the business name, logo, and call reason.
Technical Requirements: STIR/SHAKEN And Attestation Levels
STIR/SHAKEN (Secure Telephone Identity Revisited / Signature-based Handling of Asserted information using toKENs) is the FCC-mandated framework for authenticating caller ID. As of December 31, 2023, voice service providers, with limited exceptions, must implement STIR/SHAKEN in their IP networks under 47 CFR 64.6301 and 64.6302.
| Attestation Level | Definition | Branded Caller ID Eligibility |
|---|---|---|
| A (Full) | Provider authenticated the caller, has a direct relationship, and verified authorization to use the number | Required for branded display on most carrier programs |
| B (Partial) | Provider knows the caller but has not verified number authorization | Blocked on most carrier branded calling programs |
| C (Gateway) | Provider is a gateway for traffic from outside its trust domain | Not eligible for branded calling |
As the table shows, A-level attestation is the only level that qualifies for branded display on most carrier programs. For branded caller ID, A-level attestation functions as the baseline. Under a 2025 amendment (90 FR 40255), a provider that outsources signing to a third-party service must still make attestation-level decisions itself, a duty now stated in 47 CFR 64.6301(b). High-volume callers need to register their numbers and confirm that their carrier signs calls with the provider’s own certificate.
One key distinction is where signing occurs. STIR/SHAKEN attestation is signed at the originating service provider, the carrier, not at the dialer or CRM. Any tool that claims its dialer signs STIR/SHAKEN is describing the process inaccurately.
Carrier-Specific Requirements For Verizon And T-Mobile
Each major U.S. carrier operates its own branded caller ID program with distinct registration portals, verification workflows, and display capabilities. As of September 2026, branded calling on T-Mobile and Verizon is generally available, while AT&T’s broader branded calling ecosystem continues to expand. AT&T is expected to more fully enter the branded calling ecosystem in 2026.4 The table below compares attestation, display name, logo, and call reason requirements across Verizon and T-Mobile.
| Requirement | Verizon | T-Mobile |
|---|---|---|
| Attestation Required | A-level | A-level, consistent with the industry-wide standard that branded calling information must be conveyed with A-level attestation |
| Display Name Limit (Basic) | 15 characters | 32 characters |
| Logo Support | Yes (256×256 BMP) | Yes (256×256 BMP) |
| Call Reason Support | Yes (Enhanced tier) | Yes (Enhanced tier) |
| Carrier Review Time | Varies by carrier and submission, with review periods ranging from several days to a few weeks | Varies by carrier and submission, with review periods ranging from several days to a few weeks |
All carriers rely on STIR/SHAKEN attestation and may apply additional criteria. Requirements change frequently, so teams should confirm current carrier documentation before submitting.
Step-By-Step Branded Caller ID Verification Checklist
This checklist outlines the standard onboarding sequence for branded caller ID registration. Consult qualified counsel and your carrier’s current documentation before you move forward.
- Confirm legal registration. Verify that the business is legally incorporated and registered to operate in the U.S., with an active EIN or DUNS number.
- Verify trademark status. Confirm that the display name matches the registered business name or a USPTO-verified trademark before you submit.
- Choose a compliant-focused provider. Work with a provider that holds its own FCC carrier license and can issue branded caller ID at the carrier level with its own STIR/SHAKEN certificate.
- Complete carrier registration. Submit the carrier’s registration form with accurate business details, including EIN, website, and authorized representative contact. Register each number individually before carrier submission.
- Submit required documentation. Provide proof of trademark, a signed Letter of Authorization, and logo files that meet carrier specifications, typically 32-bit BMP at 256×256 pixels.
- Pass carrier review. Carriers review submissions on timelines that vary by carrier and by submission. A test call may be required before approval.
- Configure technical setup. Confirm that the dialer routes calls through the provider’s STIR/SHAKEN-signed path with A-level attestation using the provider’s own certificate.
- Monitor and maintain. Update RMD filings within 10 business days of any change, respond to spam-label disputes within 24 hours, and track complaint rates and call volume per number.
Once these steps are complete, the branded caller ID setup should align with current program requirements, although the regulatory environment continues to evolve.

2026 Regulatory Updates And Future Outlook
Several developments in 2025 and 2026 are reshaping how organizations approach branded caller ID compliance.
FCC Third-Party Authentication Order. The FCC’s Eighth Report and Order (WC Docket No. 17-97), adopted November 21, 2024, requires providers to make all attestation-level decisions consistent with STIR/SHAKEN technical standards, even when signing is outsourced. Every provider must register with the STIR/SHAKEN Policy Administrator, obtain its own SPC token, and authenticate calls with its own certificate.
FCC Proposed Rules On Verified Caller Identity. The FCC has proposed requiring terminating providers to transmit verified caller name or other caller identity information for presentation on a consumer’s handset whenever they transmit an indication that a call received an A-level attestation.4 If adopted, this proposal would make A-level attestation visible to end users at the device level.
iOS 26 Call Screening. Apple’s iOS 26 introduces a “Screen Unknown Callers” setting with three options: “Never” (calls ring normally), “Ask Reason for Calling” (callers provide a reason before the iPhone rings), and “Silence” (calls are silenced and sent to voicemail). 66% of all iPhones were running iOS 26 within five months of its release, and even at modest opt-in rates for the screening feature, call centers report 15 to 20% drops in connect rates on iPhone-heavy lead lists.3 Branded caller ID with A-level attestation helps calls present a recognizable identity instead of appearing as an unknown number that may be silenced.
Android Verified Calls Expansion. Google’s Android 2026 security updates introduce verified financial calls, a spoofing protection feature that automatically ends calls from spoofed numbers impersonating participating financial institutions. This reflects a broader mobile OS trend toward stronger identity verification and anti-spoofing controls.
FCC Know-Your-Customer Proceeding. The FCC’s April 30, 2026 FNPRM on enhancing KYC requirements (CG Docket No. 17-59) proposes stricter customer verification standards for voice providers. If adopted, these rules would likely tighten branded caller ID registration requirements across the industry. Organizations should consult qualified counsel for guidance on how proposed rules may affect their specific operations.
Common Branded Caller ID Pitfalls And How To Avoid Them
Using a name that does not match the trademark. Carriers reject submissions when the display name does not match registered business or trademark records. Teams should verify USPTO status before they submit.
A related pitfall involves ongoing accuracy. Failing to maintain accurate registration. Business changes such as mergers, rebranding, or address changes can invalidate registration. RMD filings must be updated within 10 business days of any change.
Ignoring attestation levels. B or C-level attestation does not qualify for branded display on most carrier programs. Operations leaders should confirm that the provider signs calls at A-level with its own certificate.
Another risk sits at the other end of the spectrum. Over-attesting traffic. Claiming A-level attestation for traffic that does not qualify is a compliance issue that has drawn increased FCC enforcement. Working with a provider that makes attestation decisions consistent with FCC rules helps reduce this risk.
Neglecting number reputation. Branded caller ID does not override spam labels when numbers carry poor reputations. Most carrier algorithms auto-label numbers as “Spam Likely” when daily call volume exceeds roughly 200 to 250 outbound calls per day per number. Reputation management remains a separate, ongoing discipline.
Why Plura AI Fits Compliance-Focused Outbound Teams
These pitfalls often trace back to a single issue: relying on a provider that does not control its own carrier infrastructure. Working with an FCC-licensed carrier that issues branded caller ID at the carrier level addresses that gap. Plura AI solves the branded caller ID compliance problem at the infrastructure layer. Plura is an FCC-licensed carrier that owns its carrier stack and issues branded caller ID directly under its own FCC carrier license and operating company number.
Key capabilities for compliance-focused organizations build on each other.
- FCC-licensed carrier status. Plura holds its own FCC carrier license with STIR/SHAKEN authentication on every outbound call, signed with Plura’s own certificate. This foundation enables carrier-level control.
- Carrier-level branded caller ID. Because Plura operates as the carrier, calls present with the verified business name, logo, and call reason under Plura’s carrier identity rather than a reseller’s footprint.
- Built-in compliance support. Real-time DNC scrubbing, TCPA-litigator screening, automated quiet hours, and immutable consent logging run inside the platform before every outbound contact.1 These controls support compliance programs, while customers remain responsible for their own obligations.
- AI-powered dialing on the same stack. Plura’s AI Predictive Dialer routes calls over this infrastructure, with branded caller ID on every call to support answer rates.
- 100% U.S. infrastructure. Voice origination, model hosting, and data storage operate on domestic infrastructure, which helps organizations align with FCC rules and state onshoring expectations.
For organizations running high-volume outbound across regulated verticals, Plura’s AI SMS and AI voice agent channels share a single stateful conversation database, so a customer who texted at 9 a.m. is recognized when the call arrives at noon. Compare plans on Plura’s pricing page to align capabilities with your volume and channel mix.

Frequently Asked Questions
What Is The Difference Between CNAM And Branded Caller ID?
CNAM is a legacy system that displays a name pulled from a static carrier database, limited to 15 characters, with inconsistent delivery across networks. It often shows “WIRELESS CALLER” or “UNKNOWN” on mobile devices. Branded caller ID is carrier-delivered and verified in real time via STIR/SHAKEN. On enhanced tiers, it can display a business name, logo, and call reason on supported devices. The two systems operate independently, and branded caller ID does not replace CNAM for landline delivery.
What Documents Are Needed For Branded Caller ID Registration?
Registration typically requires the legal business name and address, EIN or DUNS number, proof of trademark registration or business name authorization, a website URL with a visible privacy policy, an authorized representative’s name and contact information, and a signed Letter of Authorization. For enhanced tiers, carriers may also request a logo file in 32-bit BMP format at 256×256 pixels and a call reason description. Exact requirements vary by carrier and provider, so teams should review provider documentation and consult qualified counsel.
Does Branded Caller ID Guarantee Calls Will Not Be Marked As Spam?
Branded display and spam labeling operate as separate carrier systems. A branded number with poor reputation, high complaint rates, excessive call volume, or calling patterns that resemble robocall traffic can still be flagged as “Spam Likely.” Branded caller ID strengthens trust signals and answer rates when paired with responsible calling practices, but analytics engines continue to score numbers based on traffic patterns and complaint data. Number reputation management remains an ongoing operational requirement.
What Are The STIR/SHAKEN Attestation Levels And Which Is Required For Branded Calling?
STIR/SHAKEN defines three attestation levels. A-level, or Full, means the originating provider authenticated the caller, has a direct relationship with that caller, and verified the caller’s authorization to use the specific calling number. B-level, or Partial, means the provider knows the caller but has not verified number authorization. C-level, or Gateway, applies to traffic from outside the provider’s trust domain. Branded caller ID programs on major U.S. carriers require A-level attestation. B and C-level calls are typically blocked from branded display. The originating carrier, not the dialer or CRM platform, makes the attestation decision.
How Does iOS 26 Affect Branded Caller ID For Outbound Callers?
iOS 26 introduces a “Screen Unknown Callers” setting with three options for numbers not saved in contacts: allow calls to ring normally, prompt the caller to state their name and reason before the phone rings, or silence the call and send it to voicemail. Calls from spam-flagged or unregistered numbers are most likely to be silenced. Branded caller ID with A-level attestation helps calls present a verified business identity instead of appearing as an unknown number. As mentioned earlier, the rapid adoption of iOS 26 makes this a material operational concern for any organization running high-volume outbound on iPhone-heavy lead lists.
Conclusion: Practical Next Steps For Your Team
Branded caller ID compliance spans legal registration, technical authentication, and carrier-specific verification. Organizations that maintain call deliverability in 2026 treat it as an ongoing operational discipline rather than a one-time setup project.
Practical next steps:
- Audit the current setup. Review STIR/SHAKEN attestation levels, carrier registrations, and number reputations across active campaigns.
- Engage a carrier-level provider. Work with an FCC-licensed carrier that issues branded caller ID at the carrier level and signs calls with its own certificate.
- Run a controlled pilot. Deploy branded caller ID on a subset of numbers and measure answer rates before a full rollout. Coordinate with qualified counsel on any regulatory questions specific to your organization.
