Caller ID Mapping and Calls with a Check Mark
Getting an outbound call answered is one of the biggest challenges in telemarketing, and it starts with a strong Caller ID mapping strategy paired with a telecom carrier that signs calls with an A attestation — the combination that produces "calls with a check mark."
What is Caller ID mapping?
Caller ID mapping, or Caller ID management, lets a business control what appears on a recipient's Caller ID for an outbound call — typically a recognizable company name or number more likely to get answered than an unknown one.
Building a mapping strategy
- Choose a recognizable name or number tied to your brand or company, rather than something generic.
- Keep it consistent across every outbound channel and campaign — switching between a local number and a toll-free one across campaigns confuses recipients and lowers the odds of an answer.
- Optimize for local area codes where your business operates in multiple regions; a local number can raise the odds of an answer by up to 40%.
- Monitor for spam complaints, including offering an opt-out and watching feedback to avoid negative brand associations.
Calls with a check mark
Wireless carriers are likely to block or label calls transmitted without a SHAKEN A attestation. Using a telecom provider like Quality Voice & Data ensures calls originate and deliver with an A attestation — each carrier has its own way of signaling verification, with Verizon Wireless, for example, displaying "Calls with a check mark have been verified by the carrier" in call history. If a CNAM is also stored in the national CNAM database, Verizon includes it when delivering the call.
Without a strong Caller ID mapping strategy and SHAKEN-signed calls, recipients are more likely to ignore an unknown or unidentified number. Together, correct name display and a verified checkmark give recipients real confidence to trust and answer the call — boosting both the success rate of outbound telemarketing and conversions downstream. QVD's Trusted Call Completion® combines local Caller ID mapping, real-time monitoring, instant remediation, elastic SIP trunks, and industry-leading call authentication as one of the few certified SHAKEN Service Providers signing calls with an A attestation every time.
