Port Your Existing Number to JustCall

Keep your current phone number and bring it to JustCall. Porting transfers ownership from your existing carrier with zero downtime — your number stays active throughout the process.

Available on: All plans

How porting works

1. Submit a port request — Log in to JustCall, go to Phone Numbers, and click Port Number
2. Provide verification documents — Upload ownership proof (varies by country)
3. JustCall processes the transfer — Timeline depends on the country of origin
4. Number goes live on JustCall — Your number switches over at the scheduled porting time

Your number remains active with your current provider until the transfer completes. No downtime, no missed calls.

What you'll need

• The phone number(s) you want to port
• A Customer Service Record (CSR) from your current provider
• Your account number with the current carrier
• A port-out PIN (if your carrier requires one)
• A Letter of Authorization (LOA) — dated within the last 30 days

All information must match your current provider's records exactly. Mismatches are the most common reason for porting delays.

Timeline and costs

Other countries may have different timelines. Contact support for country-specific estimates.

Important

• Do not cancel your current provider until porting is complete
• Your number must be active with your current carrier — disconnected numbers cannot be ported
• Send all porting documents to porting@justcall.io

Common reasons for porting denial

1. Outstanding fees — Settle any balance with your current carrier
2. Information mismatch — Name, address, or account number differs from carrier records
3. Inactive number — Reactivate the number before resubmitting
4. Unauthorized signer — The LOA must be signed by an authorized account holder
5. Wrong PIN — Get the correct port-out PIN from your carrier
6. Missing account number — Request it from your current provider
