Number portability is the ability of a phone user to keep their existing phone number when switching from one service provider to another. It ensures that users do not have to change their phone number — a key part of their identity — just because they want better service, lower costs, or new features from a different telecom provider.
This feature is crucial in modern telecommunications and is widely supported in most countries.
Types of Number Portability
There are three main types of number portability:
Mobile Number Portability (MNP):
This allows mobile phone users to switch carriers without changing their number. It is the most common form and is supported in countries like India, the USA, UK, and most of Europe.
Fixed-Line Number Portability (FLNP):
This allows users to keep their landline number when changing service providers.
Service Provider Portability:
Users can retain their number while switching between recent mobile phone number data different types of services (for example, from a landline to VoIP).
Why is Number Portability Important?
Customer Freedom:
It empowers users to choose providers based on service quality or pricing without losing the number they’ve used for years.
Improved Competition:
It puts pressure on telecom companies to improve their offerings since users can easily switch providers without penalty.
Simplified Communication:
Since the number stays the same, there’s no need to inform friends, family, or clients about a new number.
How Does Number Portability Work?
The process may vary by country, but generally follows these steps:
Request Porting:
The user contacts the new telecom provider and requests to port the number.
Generate Porting Code:
A unique code (called UPC, PAC, or Porting Authorization Code) is sent via SMS or issued by the current provider.
Submit Documents:
ID proof and address verification may be required.
Verification & Transfer:
Once verified, the new provider coordinates with the old one. The number is transferred, usually within a few hours to a few days.
During the process, users may experience brief downtime, although most ports are seamless.
