Choosing phone numbers for your AI agent

Your 365 Agents number is the endpoint your AI agent answers calls on. The right choice depends on how you plan to use it.

Local numbers

A local area code (matching the region you're serving) has the highest answer rate. Recipients are much more likely to answer a local number than an out-of-state one.

• Best for customer service, appointment reminders, sales follow-up

• Ideal for local businesses serving a specific region

Toll-free numbers (800, 888, 877, etc.)

Broadly recognizable and nationally neutral. Often associated with established businesses. Harder to block, but also less personal.

• Best for national brands, customer support hotlines

• Good for any inbound-primary use case where you want a single memorable number

Multiple numbers for the same use case

If you're running an outbound campaign to many recipients, spreading traffic across multiple numbers can help — up to a point. Each number needs to be aged and registered individually, and carriers actively look for "snowshoeing" (spreading a single message across many numbers to evade filters).

Our recommendation: for most businesses, one primary number per use case. For franchise or multi-location businesses, one number per location.

What to avoid

• Using the same number for marketing and 2FA — marketing reputation issues will hurt your 2FA delivery

• Using a brand-new number for day-one high-volume outreach — new numbers get mislabeled more easily

• Vanity patterns that could resemble phishing (numbers that closely match bank or government lines)
