How to Prevent Your 800.com Calls from Being Marked as Spam or Scam

If your 800.com calls are showing up as "Spam" or "Scam" on your customers' phones, you're not alone — carriers have tightened spam filtering across the board, and legitimate business calls sometimes get caught in the mix. This isn't caused by 800.com; it's a nationwide shift by carriers like AT&T, Verizon, and T-Mobile.

This article covers the quick fixes. For a full breakdown of why this happens, glossary of terms, and an FAQ, see Blocked Calls and "Spam Likely" Caller ID.

Note: This article is about outbound calls being labeled as spam. If you're getting spam calls into your 800 number, see Receiving Spam Calls on Your 800 Number instead.

Why This Happens

Calls are often flagged as "Spam" or "Scam" when they share characteristics with robocalls or telemarketing, such as:

  • High call volumes in a short period
  • Short call durations
  • Frequent calls that go unanswered
  • Repeated calling of numbers that don't answer

Legitimate calls — appointment reminders, customer service check-ins, business inquiries — can unintentionally trigger these same filters.

Quick Fixes

  1. Register your numbers. Use the Free Caller Registry to flag your number as business-affiliated. This lasts 180 days; submitting directly to carriers (below) is more permanent.
  2. Submit for carrier verification. Each major carrier has its own review process:
  3. Keep call patterns consistent. Sudden spikes in volume or duration can raise flags. Pace outbound calls rather than sending large bursts.
  4. Keep calls meaningful. Very short or immediately-dropped calls are more likely to get flagged. Make sure recipients have a reason to stay on the line.
  5. Get consent before calling. A clear opt-in process for customers reduces the chance your calls get reported as spam.
  6. Ask customers to save your number. Saved contacts are rarely flagged.

Does Updating My CNAM Help?

CNAM (Caller ID Name) and spam/scam labels are separate systems. Spam labels are generated mainly from call behavior, not identification data — so while an accurate CNAM helps with brand recognition, it won't directly prevent a spam label. It's still worth keeping updated for the calls that do get answered.
