Number Reputation is now available on Telnyx

26, Jun 2026

Your outbound calls keep getting labeled Spam Likely and you have no way to see why or do anything about it. Number Reputation fixes that by letting you query the spam reputation of every outbound number across the major call-analytics networks US carriers rely on, then remediate the numbers that are flagged. It is a standalone monitoring product, so it reports reputation and gives you a remediation path without changing how your calls are placed.

Why it matters

When a number gets flagged as spam, customers stop answering and your appointment reminders, account notifications, and support calls go straight to voicemail. Without visibility into how carriers score your numbers, you are guessing. Number Reputation gives you a clear spam risk for each number, the detailed metrics behind it, and a path to remediate flagged numbers through Telnyx's integrations with the analytics providers, so you can protect answer rates instead of reacting after the damage is done.

What you get

  • Spam risk scoring: An overall low, medium, or high spam risk for every outbound number, sourced from the call-analytics networks carriers use.
  • Detailed reputation metrics: Maturity, connection, engagement, and sentiment scores from 0 to 100, plus a spam category for flagged numbers.
  • Remediation across providers: Submit flagged numbers for remediation through direct integrations with the major analytics networks.
  • Automatic monitoring: Re-check your numbers on a schedule you control, from business-daily to monthly, so reputation data stays current.

How it works

You register your business as an Enterprise, then render, sign, and upload a Letter of Authorization to authorize monitoring for your numbers. You enable Number Reputation with that LOA, and your details are submitted for automated vetting that takes minutes. Once both the reputation status and the LOA status are approved, you associate your US phone numbers, up to 100 per request in E.164 format. You can then query reputation scores, with cached results free and fresh live checks billed per query, and let automatic monitoring re-check your numbers on your chosen schedule.

Pricing

  • Number Reputation: $100 per month per Enterprise.
  • Reputation checks: cached results are free, fresh live checks are billed per query, and remediation is billed per query.
  • Choose pay-as-you-go with no commitment, or volume-based contract pricing with discounted rates, free 24/7 support, and a dedicated customer success manager.

Availability and expectations

Number Reputation covers US numbers in E.164 format on verified and enterprise-level accounts. It can detect and help remediate spam labels through direct integrations with the major analytics providers, but it cannot guarantee labels will not appear. Receiving carriers and analytics providers ultimately control what is displayed, and spam labeling is driven by many factors including call volume, calling patterns, recipient feedback, and carrier algorithms.
