Are you seeing one of these symptoms?
This article is for you if your outbound calls are doing either of these things:
- The person you’re calling sees “Spam Likely,” “Scam Risk,” “Fraud Risk,” “Potential Spam,” or “Telemarketer” on their phone when you call. The call still rings — they just have to decide whether to pick up something that looks like junk.
- The call doesn’t go through at all. Your phone shows “Forbidden,” “Call Failed,” “Network Blocked,” or simply doesn’t ring on the other end. The receiving phone company is rejecting the call before it ever gets to the person you’re trying to reach.
Both come from the same root cause — your business number has been flagged in the spam-detection systems the major phone carriers use. The second symptom (calls being blocked outright) is what happens when a flag escalates: instead of just labeling your call, the carrier starts refusing to deliver it. The fix path is the same in both cases.
Why this happens
The big U.S. carriers (AT&T, Verizon, T-Mobile) feed their caller ID screens from spam-analytics companies (Hiya, First Orion, TNS). Those companies score every number based on calling patterns and recipient complaints. A number gets flagged when:
- It was spoofed by a scammer at some point (which puts heat on the real owner).
- It dials a lot of unique numbers in a short window — a normal pattern for a clinic, a sales team, or a dispatch line, but it looks like a robocaller to the algorithm.
- It got reported as spam by even a small number of recipients.
- Outbound calls are short or get abandoned quickly.
A flag is not permanent and it’s not a verdict on whether you’re legitimate. It’s just a score, and the score can be cleared.
Healthcare and appointment-reminder calls: The TCPA has specific carve-outs for HIPAA-covered healthcare communications, including appointment reminders, prescription notifications, and similar patient outreach. If you’re calling patients about care, you’re on the right side of the rules — but carrier spam analytics don’t know that, and they’ll still flag your number based on call patterns alone. The fix is the same as for any other business: get the number registered with the carrier analytics partners.
The two ways to fix it
Option A — The managed fix: Press8 Number Reputation Management (recommended)
Press8 offers a paid service called Number Reputation Management (NRM) that handles all of this on your behalf:
- We register your numbers with the three carrier-analytics partners (Hiya for AT&T, First Orion for T-Mobile, TNS for Verizon).
- We continuously monitor each number’s reputation across all three.
- When we see an improper “Spam Likely” or “Scam Risk” label, we contact the carrier and advocate for removal — you don’t have to chase it yourself.
- You get answer-rate tracking and alerts.
Pricing: $95 per entity per month + $9.99 per DID per month. Both are recurring.
Why we recommend NRM over the do-it-yourself path: The free registration sites below do work, but a successful delisting isn’t permanent. Carrier analytics re-score numbers continuously, and a number that’s clean today can get re-flagged next week from a single new complaint — which means you’d have to refile the same forms over and over. NRM is monthly recurring precisely because the remediation needs to be ongoing.
Best applied across all your numbers, not just the one flagged. A number that’s clean today can flip tomorrow, and the pricing math favors covering the whole company at once — you pay the entity fee whether you’re registering one DID or fifty.
Learn more: press8.com/number-reputation-management — or open a ticket at press8.com/support and we’ll get you set up.
Timeline: Up to about two weeks for remediation status to update once we engage a carrier on a flagged number.
Option B — The do-it-yourself path (free, but temporary)
If you’d rather handle the registrations yourself, here are the official channels. Just be aware these are stopgaps — see the note above about re-flagging.

Tips when submitting:
- Choose the Business category if it’s available.
- Use your real, registered business name — not a DBA or a nickname.
- Be ready to attach proof of ownership (website, recent utility bill addressed to the business, business license).
- Expect 24 to 72 hours for new registrations to propagate to the carrier analytics. It is not instant.
- After 72 hours, test (see below) to confirm the flag has lifted.
Flagged by a carrier or labeler not listed above? USTelecom’s Industry Traceback Group maintains a complete directory of call-labeling and call-blocking contacts across the industry — useful when the flag is coming from a non-mainstream carrier or analytics provider: ustelecom.org/the-industry-traceback-group-itg/call-labeling-and-blocking-points-of-contact.
How to confirm a flag is the actual problem
Before doing anything else, narrow down where the flag is coming from.
- Call your own number from different carriers. Have someone on AT&T, someone on Verizon, and someone on T-Mobile each call themselves from your business line (or have you call them) and report exactly what they see — “Spam Likely,” “Scam Risk”, nothing at all, or a fast busy / failed call. The wording is a clue: each carrier’s analytics partner uses different labels.
- Note whether the problem is universal or carrier-specific. If only T-Mobile recipients see it, the flag is at First Orion. If only Verizon sees it, it’s at TNS. If everyone sees it, all three databases have you.
- Check whether calls are being blocked, not just labeled. If recipients say their phone never rang and your phone said “Forbidden” or “Call Failed,” that’s the escalated version of the same problem — the carrier has gone from labeling to outright rejection.
Calling practices that help (and ones that hurt)
These habits feed the spam algorithms whether you mean to or not. Adjusting them makes future flags less likely:
- Keep average call duration above ~15 seconds. Lots of sub-5-second calls look like a robocaller hanging up on no-answers.
- Don’t dial the same area code at high volume in short bursts. Pace outbound campaigns where you can.
- Don’t use “neighbor spoofing” — outbound caller IDs that share an area code and prefix with the recipient. Carriers specifically train against this.
- Identify yourself and your business clearly when the call is answered.
- Make sure your CNAM (the caller ID name) matches your business name in public records. Press8 can verify and update this for you — open a ticket.
- Stay TCPA- and FCC-compliant on your dialing practices. Healthcare clients: remember you have specific carve-outs but should still keep records.
Future-proof: branded calling
To eliminate “Spam Likely” risk and increase pickup rates, the next level beyond registration is Branded Caller ID (sometimes called Rich Call Data or RCD). Instead of just a number, the recipient sees your logo, business name, and a reason for the call. Available through First Orion, Hiya, and TNS. Press8 can help scope this for higher-volume outbound operations — ask us.
📞 Quick action flow
- Confirm the flag — test from multiple carrier networks, note exactly what recipients see.
- Decide DIY or managed — either register at Free Caller Registry plus the individual databases (free, temporary) or sign up for Press8 NRM (paid, ongoing, recommended).
- Wait 24-72 hours for new registrations to propagate.
- Retest on the same carriers as step 1. Calls should now go through and display normally.
- Adjust dialing patterns so flags don’t come back.
- Open a Press8 ticket if you also want STIR/SHAKEN A-attestation verified and your CNAM checked — both make future flags less likely.
