What is Number Porting?
Number porting, also called a number transfer or carrier switch, is the process of moving your phone number from your current provider to a new one, without changing the number itself. Businesses typically port their number to get better rates, more reliable service, or features their current provider doesn't offer, like AI-powered call routing or built-in analytics.

How to Port Your Existing Phone Number to KrispCall?
Check Your Porting Eligibility
Use KrispCall's free number porting eligibility checker to confirm your phone number can be ported, and see exactly which documents your carrier requires.
Submit Your Port Request
Every KrispCall plan offers number porting. Subscribe to one plan and email porting@krispcall.com with your number(s) in international format, a signed Letter of Authorization (LOA), your current provider's name, a recent bill, and other required documents. Note: Don't cancel your current plan till it’s fully ported.
We Review Your Documents
Our team verifies your submission and confirms eligibility within 1 business day. We'll reach out directly if anything needs correcting.
We Contact Your Current Carrier
KrispCall submits the port request to your losing carrier and manages all communication on your behalf. There is a series of communication back and forth between KrispCall and the current carrier. This step typically takes up to 7 days.
Your Carrier Makes a Decision
Your current provider approves the port or flags a correction. If rejected, we'll tell you exactly what to fix, usually a simple detail mismatch. Most issues resolve in one round.
Port Confirmed, You're Live
Once approved, you'll get your porting date by email. It might take 3-4 weeks at most to complete the porting of your phone number to KrispCall. Your number transfers on that date, with a temporary number active until then, so calls never stop.
Exactly what each country needs
Requirements vary by country and number type. Pick a country to see what to prepare.
