SPAM!

The Hard Truth

There's no magic "unblock" button. US carriers use multiple overlapping systems. You need to dispute with each carrier AND their analytics providers separately.

Success rates: ~10% via carrier support, 20-30% via analytics providers, 70-90% via rest + STIR/SHAKEN fix. The winning strategy combines all three approaches.

The US Spam Detection Ecosystem

Unlike some countries with centralized systems, the US has multiple overlapping layers of spam detection.

Analytics Providers to Contact

STIR/SHAKEN: The Key to Prevention

FCC-mandated caller ID authentication

Level A

Full Attestation - You own the number and are authorized to use it. Lowest spam risk.

Level B

Partial Attestation - You're authorized to use the number but may not be the original owner.

Level C

Gateway Attestation - Origin cannot be verified. High spam risk. Red flag for carriers.

How to Improve Your Attestation

  1. 1Contact your VoIP provider about their STIR/SHAKEN implementation
  2. 2Ensure your numbers are properly registered in their system
  3. 3Verify your business identity with required documentation
  4. 4Request Level A attestation once verified

Recommended Rest Periods

Risk LevelRecommended Action
Score 30-70% (Suspicious)Stay vigilant, adjust practices
Score 70-80% (Nuisance)15 days complete rest
Score 80-90% (Spam)30 days complete rest
Score 90%+ (Scam/Fraud)Consider new numbers

Why Was Your Number Flagged?

01

High Call Volume

Making too many calls per hour triggers carrier algorithms. Over 100 calls/day from a single number raises red flags.

02

User Complaints

Recipients marking your calls as spam in their phone app or reporting to carriers directly.

03

Short Call Duration

High rate of calls under 10 seconds suggests robocalling or unwanted sales calls.

04

Poor STIR/SHAKEN

Low attestation level (B or C) or missing caller ID verification makes you suspicious to carriers.

Stay TCPA & FCC Compliant

TCPA Requirements

  • Prior express written consent for marketing calls
  • Calling hours: 8am-9pm recipient's local time
  • Honor opt-out requests immediately
  • Maintain internal do-not-call list
  • Scrub against National DNC Registry

FCC Robocall Rules

  • STIR/SHAKEN caller ID authentication required
  • Register in FCC Robocall Mitigation Database
  • No caller ID spoofing with intent to defraud
  • Identify yourself at the beginning of calls
  • Provide callback number when requested

DANGER ZONE: DO NOT DO THIS

X

Switch to new numbers immediatelyUsing the same calling patterns will get new numbers flagged within 48 hours.

X

Call carrier customer service repeatedlyFrontline agents don't have access to spam filtering systems. You need the business/enterprise dispute forms.

X

Keep calling hoping it clearsEvery flagged call generates more reports, making your situation exponentially worse.

X

Make 'test calls' during cooldownEven one call can reset the flagging timer and waste weeks of rest.

X

Trust 'number cleaning' servicesNobody can guarantee removal. Anyone promising instant results for a fee is likely scamming you.

If Disputes Fail: Alternative Strategies

Rest + Monitor

  1. 1Put flagged numbers on complete rest
  2. 2Monitor scores weekly with DIDCHECKS
  3. 3Resume when risk drops below 40%
  4. 4Implement better calling practices

Fresh Numbers

  1. 1Order new DIDs from your provider
  2. 2Verify STIR/SHAKEN Level A attestation
  3. 3Check reputation BEFORE using
  4. 4Change your calling patterns first

Number Rotation

  1. 1Maintain 5-10 numbers minimum
  2. 2Rotate numbers every 50-100 calls
  3. 3Monitor all numbers continuously
  4. 4Retire numbers before they're flagged
