Why Verified Data Reduces Wasted Dials in Call Centers
Industry Intelligence Center · Updated: November 2025 · Reviewed by: SICCODE Research Team
Wasted dials drain productivity and morale. The fastest way to recover hours and improve outcomes is to start with verified, classification-aligned data. This ensures that each call reaches a relevant business, reduces time spent on wrong numbers, and increases the odds of meaningful conversations that lead to meetings and revenue.
The Cost of Unverified Data
Unverified lists lead to low connect rates, repeated attempts on dead numbers, and off-fit conversations. These inefficiencies compound across teams—raising your cost per opportunity. By contrast, verified SIC/NAICS targeting focuses your time on companies that align with your ICP and are statistically more likely to convert.

How Verification Translates into KPIs
- Higher connect rates: Clean phone fields and standardization reduce failed attempts.
- More qualified conversations: Classification precision cuts off-fit calls and improves script resonance.
- Lower cost per meeting: More appointments from the same dial volume.
- Rep productivity gains: Less friction per hour, more pipeline per rep.
Build Lists that Protect Rep Time
- Start with industry fit: Select codes from the SIC Directory and NAICS Directory that map to existing wins.
- Apply geography and size filters: Focus on regions and company bands that match historical success.
- Verify phone fields: Align formats and remove invalid numbers before dialing.
- Refresh regularly: Quarterly updates keep your list accurate as the market changes.
Case Example: Cutting Wasted Dials by a Third
An inside sales team targeting SIC 5084 (Industrial Machinery and Equipment) replaced a generic list with verified SIC-matched data. Connect rates rose 22%, wasted dials fell by 34%, and appointments per rep increased 41%—without adding headcount. The change: list quality.
