The Fraud Graph — Your Digital Neighbors Affect Your Score

Why shared numbers, reused addresses, and sketchy links hurt

Verification platforms map relationships among phone numbers, addresses, domains, and devices—the fraud graph. If your contact info was ever tied to a high-risk profile (even a previous tenant), your credibility drops.

What It Means

  • Reusing a phone number from an old venture can inherit its reputation.
  • Mailbox-only locations and mass-used suites appear risky by default.
  • Vendors and lenders often apply this risk before they contact you.

Why It Matters

Clean identifiers shorten approvals and reduce manual review. Contaminated identifiers quietly depress limits and offers.

How to Fix It

  • Use a dedicated business phone line not shared with other entities.
  • Avoid recycled VOIP numbers and mass-tenant mailboxes when possible.
  • Stand up a clean domain + email and keep them exclusive to the business.
Pro Tip: If you inherit a risky number, request spam-label remediation (Hiya/Nomorobo) after porting to a reputable provider.
