Port or new number
Which one do you need?
Porting keeps a number your customers already know. A fresh number is better for new markets and clean starts.
Port your number when
- Customers already know it: support lines, hotlines, sales numbers
- It's printed on your marketing, packaging, or listings
- You want to consolidate providers without disruption
- You're switching to cut costs or add channels
Get a new number when
- You're expanding into a new country or region
- You need to spread traffic across multiple numbers
- Your current number is flagged as spam
- You're launching a separate line or brand

Fast ports
Tips for a smooth transfer.
Ports rarely fail for technical reasons. They stall on details, and a few small things keep yours on track.
Match your details exactly
Account name and address must match your current provider. Mismatches are the #1 cause of delays.
Clear any balance
Settle outstanding charges with your current provider before porting.
Keep service active
Don't cancel your current plan until the port completes. Cancelling early cancels the port.
Submit on a business day
Ports process during carrier business hours, so you get faster responses.
FAQ
Porting, answered.
What is phone number porting?
Porting moves your existing phone number to Zavu without changing the number itself. You keep the same number your customers already know. Only the provider behind it changes. Calls, texts, and WhatsApp keep working throughout.
Will my number keep working during the port?
Yes. Your number stays active on your current provider until the transfer completes, so there is no gap in service. The switch to Zavu happens instantly at the final cutover.
How long does porting take?
Most local numbers port in 2-4 business days. Toll-free and international numbers can take longer, depending on the country and your current carrier. We keep you updated at every step.
What do I need to start a port?
A recent bill or account number from your current provider, the account holder's name and address exactly as they appear on file, and a signed Letter of Authorization (LOA). Some carriers also require an account PIN or passcode.
Can I port a toll-free or international number?
Yes. Zavu supports porting local, toll-free, and international numbers across 180+ countries. Requirements vary by country, and our team confirms eligibility before you start.
What happens if a port is rejected?
Ports are usually rejected for mismatched account details or an outstanding balance. We tell you exactly what to correct and resubmit the request. You never lose your number.
