How to Port a Number - The Ultimate Guide!


Porting a number can be extremely tedious, confusing, and down right absurd depending on the carriers. Not to mention depending on the carries, type of phone, and the date in which you purchased it, can all make a huge difference in the timing, availability, portability, and process you use to port that number. This guide is created to give you a 1 stop shop on everything you need to successfully port your number.


What is Porting: Think of a phone number as a property, your carrier in a way owns the rights to that number while you have it, and depending on your agreement with your carrier, your number needs to overcome a transfer in order for you to take that phone number elsewhere, even if it's the same carrier! Side note: It is rare, but sometimes numbers are banned from certain carriers!

How to use this guide: First, find your carrier (The one you want to port from) then find the carrier you wish to port to and follow the flow by reading the info you need.


Disclaimer: It is important that you do not cancel your mobile phone contract with your current provider, until your phone number has ported (transferred) to your new mobile phone network provider. The overlap is required or you may lose the rights to your phone number and it will be immediately used by the carrier who owns it.
