Porting Your Existing Number — What to Know

JustCall makes it easy to transfer your existing phone numbers from another provider. Here is what you should know before starting.

Available on: All plans

How porting works

1. You submit documents — a Letter of Authorization (LOA) and supporting documents that verify you own the number.
2. JustCall processes the request — the porting team coordinates with your current carrier to transfer the number.
3. The number goes live on JustCall — once complete, all calls and messages route through your JustCall account.

Key things to know

• No downtime. Your number continues working throughout the porting process.
• Do not cancel your current provider until JustCall confirms the port is complete. Canceling early can cause the number to be released and lost.
• Documents vary by country. Each country has specific requirements — check the country-specific porting guide for your region.
• LOAs must be recent. Most countries require the LOA to be dated within the last 30 days.
• You can port out of JustCall anytime. If you need to move your number away from JustCall in the future, you can do so freely.
