How to Transfer Your Business Number When Moving

Your Number Is Your Brand — Do Not Lose It

Whether you are switching carriers, moving offices, or transitioning to VoIP, your business phone number is a critical asset. Customers, search engines, and marketing materials all point to that number. Losing it means losing revenue.

Understanding Number Porting

Key Facts

Porting Toll-Free Numbers

Toll-free number ports follow a similar process through the SMS/800 system. They typically complete in 1-2 business days and require authorization from the current RespOrg.
