CNAM (caller name presentation) is what makes a name — rather than just a number — appear on the recipient's phone when you call in the US. For numbers rented through Myphoner, you register your caller name yourself with the industry registries; it's free and takes a few minutes. Myphoner cannot do this on your behalf, because the registries verify the business behind the number.
Where to register
Register your number(s) and business display name at both:
Free Caller Registry — freecallerregistry.com
First Orion — firstorion.com
These are the same portals we recommend for spam-label prevention, so registering also helps your numbers' reputation.
What to expect
Your display name must be 15 characters or fewer (e.g. "ACME SALES").
Propagation takes anywhere from 48 hours to several weeks, as carriers update their databases on their own schedules.
CNAM displays most reliably on landlines. On mobile phones it depends on the recipient's carrier and apps, so not every recipient will see the name.
