Keep your number

Switching providers? Keep your number, skip the downtime.

Moving phone providers should not mean new numbers on every card and sign. Your old service keeps ringing while we prepare the switch, so customers never hit a dead line.

  • Local, toll-free and international
  • No port-out fees
  • Back-out path kept open

Same number. The caller never notices the switch.

Why port

Change the system, not the number.

Your number is printed, listed and saved in more places than you think. Switch between the two options to see what each one means.

Number porting FAQs

What teams ask about porting numbers.

Everything to know before you start a port.

Local numbers are often ported the same day or the next day. Toll-free numbers typically take 2 to 4 business days. We confirm the firm order commitment (FOC) date with you before anything switches over.
