Frequently Asked Questions
What does Phone Appending deliver exactly?+
Your input file returns with direct dials and mobiles matched to named contacts, each labeled by line type and validity status so dialers and reps know what they are calling.
How do you handle do-not-call rules?+
Every number is screened against federal and state DNC registries before release, and flags are preserved in the output so downstream dialing logic stays compliant.
Why do mobile match rates differ from landlines?+
Mobile attribution relies on consented and opt-in sources, so we report honest per-type match expectations up front instead of inflating headline numbers.
Can you reverse-lookup existing numbers?+
Yes, reverse matching attaches names, titles, and employers to phone-first files, useful for inbound lead enrichment.
Can I request direct dials only?+
State that requirement in the scope. Confirm whether unavailable direct lines remain blank or whether another business number may be returned under a separate label.
Does phone appending include mobile numbers?+
Do not assume so. Confirm which types are supported for your audience and require each returned type to be clearly identified.
Will every source record receive a number?+
No. Some records may not support a reliable match or the requested line type. The output should retain those rows with an agreed status.
Does a phone-type label mean the number is safe to call?+
No. A classification is one data point. Your team must apply applicable legal, consent, suppression, and channel requirements for the intended use.
