Free Caller Registry: Who Can Use It, What It Fixes

The Free Caller Registry (freecallerregistry.com) registers a business’s outbound numbers with First Orion, Hiya, and TNS in one free form. Its Review step, read 2026-09-01, states: “The Free Caller Registry is for businesses that make calls on their own behalf. If you are registering numbers on behalf of another business, you must contact the call protection providers directly.”

First Orion, Hiya, and TNS are the three engines that score calls for the major US wireless carriers. The form lists them under “Brought to you by:”. The submit checkbox then has you “confirm that my business makes calls from the submitted phone numbers”. You also state “I am not registering these numbers on behalf of another business” (Review step).

Step 2 of 3 takes the numbers: “Add up to 20 phone numbers individually or upload a file to register more”. The terms state that the engines “may each verify and use the Registration Data”. So one form reaches all three.

Sourcing note: every registry quote on this page was read on 2026-09-01. Form quotes come from freecallerregistry.com/fcr/ (home panels, Steps 1–3 and the Review step). Terms quotes come from freecallerregistry.com/fcr/public/html/enterprise.html (the enterprise terms).

The own-behalf rule sorts outbound operations into two groups. An in-house floor that calls its own customers from numbers it holds is calling on its own behalf. Registering with the Free Caller Registry is the right first stop. A VoIP reseller filing customer numbers is not. Nor is an agency, a dialer vendor, or a BPO dialing for clients. Those callers must go to the engines directly.

Those direct routes are mapped by caller type in our business phone number registration hub. First Orion’s route has a portal and an API. It gets its own First Orion number registration walkthrough.

SIPNEX is an FCC-licensed carrier. We sign outbound calls at A-level with our own STIR/SHAKEN certificate, so registration guidance is part of our onboarding — bias disclosed. The full check-and-fix program lives in our caller ID reputation guide. This page covers the registry itself.

Is the Free Caller Registry legit?

Yes. The form headline reads “Register outbound business phone numbers for free.” It lists First Orion, Hiya, and TNS under “Brought to you by:”. Please note what the site is not. It is not the National Do Not Call Registry, not a government program, and not a carrier program. It is a shared front door to three private scoring engines. Its own “Why register?” panel describes one submission as “reaching over 400M wireless subscribers across the US”.

Many people search for it as the “free call registry”. The name on the form is Free Caller Registry, and the site is the same one.

There is no account sign-in. The only credential steps are “Verify your business email to get started,” then “Enter the code sent to your email address.” Status views belong to the engines’ own portals. Hiya’s account, for example, shows spam status and a “call performance report card” (hiya.com/products/connect/number-registration, read 2026-09-01).

The three engines score your calls for the major wireless networks:

Analytics engine	Carrier network it scores	Label recipients see
First Orion	T-Mobile	“Scam Likely”
Hiya	AT&T (ActiveArmor)	“Spam Risk”
TNS	Verizon (Call Filter)	“Potential Spam”

Source for the engine-to-carrier map: Hiya’s blog post of 2023-08-02 (blog.hiya.com/dont-pay-a-vendor-to-register-your-phone-numbers-across-carriers-use-free-caller-registry, read 2026-09-01). It lists “Hiya - Analytics engine for AT&T,” “TNS - Analytics engine for Verizon,” and “First Orion - Analytics engine for T-Mobile.” The third column is the label each carrier’s own call-filtering app displays.

Free Caller Registry vs First Orion direct registration

For a business calling on its own behalf, one Free Caller Registry form reaches First Orion, Hiya, and TNS. Anyone filing another business’s numbers is sent to the engines directly by the same Review step. First Orion’s portal and API are compared below. Hiya’s conditional rule and TNS’s missing portal follow the table. Each portal, in its own words:

	Free Caller Registry	First Orion Free Number Registration
Who may use it	“businesses that make calls on their own behalf” (Review step)	Portal: “verifies your business” (FAQ) and takes numbers “for verification” (product page); API: “enables businesses and BPOs to automate high-volume number registrations” (FAQ), right-to-use vetted (API blog, 2026-06-08)
Engines and networks	All three engines — First Orion, Hiya, and TNS — from one form	First Orion only; its FAQ says registration “ensures proper number labeling across T-Mobile and AT&T,” and its product page says “API access supports T-Mobile registrations only”
What you enter	Business identity, contact, calling data; “up to 20 phone numbers individually or upload a file to register more” (xlsx or txt under 100 KB)	Business Name, Industry, Website, Phone, Address; then numbers for verification
Stated timeline	None published on the pages read	Confirmation “within minutes” for most; registered “within days” — all three of First Orion’s timing sentences are unpacked in the walkthrough linked below
Cost	Free	Free (“Register Your Numbers for Free”); paid products are separate
Ongoing management	One submission; the registry says a number never needs registering twice (quoted below)	Customer Portal account; API access is gated (prerequisites below)

Verified 2026-09-01 against the live pages: freecallerregistry.com/fcr/ (Steps 1–3 and Review step), freecallerregistry.com/fcr/public/html/enterprise.html, firstorion.com/products/free-number-registration, firstorion.com/frequently-asked-questions, developer.firstorion.com (Business Registration API guide), firstorion.com/blog (API post, 2026-06-08).

The First Orion API is not self-serve. Its developer guide lists the “First Orion Branded Communications agreement,” Customer Portal access, and “Vetted and Approved Organization” status among its prerequisites (developer.firstorion.com, Business Registration API guide, read 2026-09-01). The vetting states and the T-Mobile-only scope are walked through in how First Orion Free Number Registration works.

Hiya is the conditional third route. Its account FAQ, read 2026-09-01, states that registration “is allowed for businesses that place phone calls on behalf of other businesses (example: lead generation services and BPOs), as long as the registering business is directly involved in leasing the phone numbers and placing the calls” (hiya.com/faq/signing-up-for-hiya-account-help). Filing for numbers you neither lease nor call from does not qualify. The row-by-row comparison of every portal is in the decision table for every registration portal.

TNS publishes no free direct registration portal on the pages we read 2026-09-01. Its reputation product is Telephone Number Reputation Monitoring, not a registration form. For an own-behalf caller, the Free Caller Registry is therefore the only free registration route to TNS. Verizon-side label disputes go through the Voice Spam Feedback form covered below.

How to register phone numbers with the Free Caller Registry

The form runs in three steps after “Verify your business email to get started”: “Tell us about your business,” “Add your phone numbers,” and “Review and accept terms.” It collects four groups of information:

1. Business identity — business name, street address, city, state, ZIP, and website URL.
2. Contact details — a contact name, a phone number, and an email address you must verify.
3. Calling data — call purpose, outbound calls per month, and any customer feedback about how your calls are labeled.
4. Your numbers (Step 2 of 3) — “Add up to 20 phone numbers individually or upload a file to register more.” The file is an “xlsx or txt file less than 100 KB,” “One phone number per line,” “10-digit US phone numbers.”

The Review step enforces the own-behalf rule. Tick the box confirming your business makes calls from the submitted numbers and is not filing them for another business. Then submit — once. The terms state that “multiple submissions of the same telephone number provide no additional value or redress functionality.” The site’s “How does Free Caller Registry work?” panel adds: “There is no need to register any number more than once.”

The terms also state that “neither Analytics Engines nor their carrier partners use Registration Data to deliver Caller ID Name.” The on-screen name is CNAM — a separate database with a separate fix. It is explained in how CNAM lookup works.

What happens after you submit — and the timeline question

The terms state that the three engines “may each verify and use the Registration Data to improve their call management services.” Each engine reviews the same submission on its own. The one promised event, in the same terms: “You will receive a message from each Analytic Engine acknowledging their receipt of the Registrant Data and the additional processes, if any, with regard to your relationship with each such Analytic Engine.” The registry publishes no processing timeline on any page we read.

What registration fixes — and what it cannot

What it fixes: registering with the Free Caller Registry attaches a business identity to your numbers with all three engines — name, call purpose, monthly volume. That is input, not a whitelist. Each engine reviews it on its own, as the terms quoted above say.

The registry spells out what it cannot fix. Registration “does not guarantee redress based on analysis that each Analytics Engine does independently.” It also “is not to be used as a replacement for caller reputation monitoring services” (enterprise terms).

A spam label is not a fixed property of a number. Scoring continues on live traffic after you register. A clean status today guarantees nothing about next week. When numbers are already labeled as spam, registration is one step of the spam-label remediation playbook, not the whole fix.

Why registered numbers get re-flagged

The engines keep scoring live behavior after you register. Hiya’s number-registration page states that “Carriers use spam detection systems that analyze call patterns and customer behavior.” It adds that “Even legitimate businesses can be flagged if recipients frequently ignore or block calls, or if the calls are perceived as disruptive” (hiya.com/products/connect/number-registration, read 2026-09-01). Registered identity does not outweigh spam-shaped traffic.

The form never asks about the second input the engines weigh: the STIR/SHAKEN attestation on each call. Whoever signs the call sets it. The A, B and C levels are explained in A-level vs B-level attestation. Analytics engines score partial (B) attestation lower on trust; the exact answer-rate gap is not something any carrier publishes.

No form fixes that half; the trunk does. Calls on a SIPNEX trunk are signed A-level under our own STIR/SHAKEN SP certificate. SIPNEX’s own filing is on the FCC’s Robocall Mitigation Database. DID-pool size and pacing stay yours — the pool math is in the caller ID reputation guide.

When to escalate beyond the registry

If a label persists on one network, work that engine’s own channel. T-Mobile: First Orion’s free direct registration at firstorion.com/products/free-number-registration, plus T-Mobile’s “Report Improperly Identified Calls” form at callreporting.t-mobile.com. AT&T: att.com/reviewmycalllabel, which redirected to Hiya’s help hub on 2026-09-01. Verizon: the Voice Spam Feedback form.

All three carrier-side channels sit in one table in the business phone number registration hub, with what each is and is not.

For the joint registry itself, the terms name a contact at each engine: FCRsupport@firstorion.com, freecallerregistry@hiya.com, and communications@tnsi.com. Label disputes run through the carrier channels above. Then verify what recipients actually see. Call test handsets on each carrier from your numbers, as our caller ID test walkthrough lays out.

Frequently asked questions

Is the Free Caller Registry legit, or a scam?

It is legit, and it is free. First Orion, Hiya, and TNS back the registry jointly. They are the three analytics providers behind the major US carriers’ spam labels. It is a single-submission portal, not a government program. Its form headline reads “Register outbound business phone numbers for free” (freecallerregistry.com/fcr/, read 2026-09-01). Be skeptical of third parties charging to register you across carriers. Hiya’s own blog post of 2023-08-02 puts it plainly: “Before you waste your money, you should know about the availability of Free Caller Registry” (blog.hiya.com).

Is the “free call registry” the same as the Do Not Call Registry?

No. “Free call registry” is a common search shorthand for the Free Caller Registry — the free form where a business files its own outbound numbers with First Orion, Hiya, and TNS. The National Do Not Call Registry is operated by the FTC. Telemarketers must scrub their dial lists against it at least every 31 days. Registering with the Free Caller Registry does nothing for DNC compliance. A DNC scrub is a compliance step, not a label fix — it helps a score only indirectly, by cutting the complaints the engines count. The FTC side is covered in our DNC scrubbing guide.

How long does the Free Caller Registry take to work?

No timeline is published. None appears on any Free Caller Registry page read 2026-09-01. Its enterprise terms promise one event only: an acknowledgment message from each analytics engine confirming receipt of your data, plus any further steps that engine requires. Each of the three engines reviews the submission on its own schedule. The figures First Orion and Hiya publish belong to their own direct registrations. None of them binds the joint form.

Does the Free Caller Registry remove spam labels?

Not by itself, and it says so: “The registration of phone numbers does not guarantee redress based on analysis that each Analytics Engine does independently” (freecallerregistry.com enterprise terms, read 2026-09-01). Registration attaches verified identity data to your numbers in all three engines’ databases. That is a positive input each engine weighs. Labels return whenever calling behavior looks spam-like, regardless of registration. So pair the submission with behavior fixes and per-engine disputes.

Can my VoIP provider submit my numbers to the Free Caller Registry for me?

No. The submit checkbox has you state “I am not registering these numbers on behalf of another business.” The form ties the submission to a business email you verify yourself. The acknowledgment each engine sends goes to the submitter — you, not your vendor. There is no provider or agent role anywhere in the three steps. Who may file at the other portals is sorted by caller type in our guide to every business phone number registration portal.

Should I resubmit numbers to the Free Caller Registry after a new flag?

No. The Free Caller Registry’s enterprise terms state that “multiple submissions of the same telephone number provide no additional value or redress functionality” (freecallerregistry.com/fcr/public/html/enterprise.html, read 2026-09-01). Hiya’s blog of 2023-08-02 adds: “Repeatedly registering your numbers is not a solution.” A returning label means an engine is re-scoring live behavior. It does not mean your registration lapsed. Respond with a dispute through that engine’s own channel. Then fix the pacing, volume, or attestation signal that earned the score.

Free Caller Registry vs First Orion registration: which should I use?

Use the Free Caller Registry when your business places the calls from the numbers you submit. One free form reaches First Orion, Hiya, and TNS. Use First Orion direct when you cannot tick that box. The registry’s Review step, read 2026-09-01, sends anyone “registering numbers on behalf of another business” to the engines themselves. First Orion has a Customer Portal for your own numbers, plus a gated API its FAQ opens to BPOs. Account steps, API prerequisites and network scope are in our First Orion registration walkthrough. Both are free. Only the registry route reaches TNS, the engine behind Verizon’s labels.
