Quick answer
Define the country, market and use case first
Start with the geography you need and whether the number is for outbound sales, inbound callbacks, an AI Voice Agent, a human dialer or a combination. Number availability and regulatory requirements vary by country and number type. If your team sells into multiple regions, decide whether one central line or several market-specific numbers makes more operational sense.

Guide section 02
Search available business lines
Use a phone-number purchasing workflow that lets you search available inventory for the market you need. Check the number type and any displayed recurring price or capability information before purchase.
In ReachFly, eligible Voice users can open the Phone Numbers area and use the Buy Phone Number workflow to search and purchase a business line.
Guide section 03
Review recurring and usage cost
The purchase decision should include recurring rental and expected voice usage. Depending on provider, location and capability, additional charges can apply for calls, messages, recording, registration or taxes.
Use the current price displayed during purchase as the source of truth rather than relying on an old blog post, because telecom inventory and rates can change.
Guide section 04
Assign the number to the correct workflow
After purchase, connect the number to the human dialer or Voice Agent that will use it and confirm the appropriate outbound identity. Keep ownership visible so team members know which line belongs to which campaign or agent.
Avoid sharing one number across unrelated workflows if that makes call history, routing or accountability difficult to understand.
Guide section 05
Complete calling policy before launch
For AI calls, configure disclosure, calling windows, suppression, retry limits and recording policy before launch. Human calling teams should also maintain do-not-contact handling, local-time rules and accurate dispositions.
A purchased number does not remove the need for lawful and responsible calling practices.
Guide principle
Keep evidence, ownership and the next action connected.
The strongest workflow is the one that lets the team understand why a lead matters, what happened, and what should happen next.
