        "content": "I couldn\u2019t find any **public Web portal** that allows you to check whether a *mobile phone number* is listed to a *specific person\u2019s name* via STIR/SHAKEN (sometimes called SHAKEN/STIR). Here\u2019s what I found, and why such a portal doesn\u2019t exist\u2014at least right now.\n\n---\n\n### What STIR/SHAKEN *Does*\n\nSTIR (Secure Telephone Identity Revisited) + SHAKEN (Signature-based Handling of Asserted Information Using Tokens) is a protocol framework enforced in the U.S. to:\n\n- Authenticate the **originating number** of a call,  \n- Verify whether the caller has the right to use that number, and  \n- Allow the terminating carrier to verify the Caller ID via digital signatures. ([docs.fcc.gov](https://docs.fcc.gov/public/attachments/FCC-20-42A1.pdf?utm_source=openai))\n\nHowever, it **does not validate or disclose the name** of the person who owns the number in the sense of \u201cthis number is registered to John Doe.\u201d SHAKEN verifies that *you\u2019re calling from the number you say you are calling from*\u2014but *not who exactly you are.* ([verizon.com](https://www.verizon.com/business/resources/support/stir-shaken-faq.pdf?utm_source=openai))\n\n---\n\n### What Some Tools *Do* Allow\n\nThere *are* tools that show the STIR/SHAKEN attestation status for a phone number. Here are a few:\n\n- **IDT Express** offers a tool where you can check your U.S. business numbers to see their STIR/SHAKEN attestation level (Full / Partial / Gateway). ([idtexpress.com](https://www.idtexpress.com/tools/stir-shaken/?utm_source=openai))  \n- **Telus Canada** has explanations for what \u201cverified\u201d looks like on compatible handsets when the call is STIR/SHAKEN authenticated. ([telus.com](https://www.telus.com/en/support/article/stir-shaken-mobile-devices-explained?utm_source=openai))  \n- **TransUnion\u2019s TruContact** service is focused on \u201cCaller Name Optimization\u201d\u2014but that\u2019s more about how businesses can present branded caller names, not confirming private individuals. ([transunion.com](https://www.transunion.com/solution/trucontact/branded-communications/trusted-call-solutions/caller-id-authentication?utm_source=openai))\n\nSo the available tools tend to focus on whether a call is signed and whether it meets the protocol\u2019s standard for attestation\u2014not matching numbers to person names for private identification.\n\n---\n\n### Why a Name Lookup Isn't Possible via STIR/SHAKEN\n\nHere are the reasons:\n\n1. **Privacy Laws**  \n   Caller ID name (CNAM) databases separate name records from the authentication framework for privacy reasons. Mobile carriers aren\u2019t allowed\u2014or do not\u2014in most cases share private individual identity data.\n\n2. **Attestation Levels Don\u2019t Include Names**  \n   Attestation levels (A / B / Gateway) describe how sure the system is about the *number\u2019s legitimacy*\u2014not about who it belongs to. ([idtexpress.com](https://www.idtexpress.com/tools/stir-shaken/?utm_source=openai))\n\n3. **No Public Registry Exists**  \n   There is no public, searchable registry where someone can enter a number and get a name. That would raise heavy privacy/identity-theft concerns.\n\n---\n\n### Summary\n\n- STIR/SHAKEN = verifies *caller number* + *right to use the number* \u2192 NOT full \u201cthis number belongs to this named person.\u201d\n- No public portal exists to cross-reference number \u2192 name via STIR/SHAKEN.\n- Some tools show whether a number is properly signed or verified under this system, *but not who owns it*.\n\n---\n\nIf you want, I can dig up what kinds of options *are* legally available (e.g. CNAM services, paid lookup tools, carrier-provided info) to see if there\u2019s a way to verify names based on phone numbers\u2014but it won\u2019t be STIR/SHAKEN-based. Do you want me to pull those up?"
