How to apply for Mobile Number Portability (MNP) in India?

Mobile Number Portability (MNP) is a popular term used worldwide, which basically means that the telecom users in a specific country retain their mobile number and still can switch their operator. Started in United Kingdon in the year 1999, the technology has been widely accepted around the globe and have been used by the citizens to the fullest. This service, however sweet it might sound comes with some prerequisites which might come in the way of your MNP process. In this post, let’s take a look at how to port your number – which will definitely save a lot of your time researching for steps in the mobile stores.


  1. The customers must use the number which they want to port for atleast 90 days (approx. 3 months) with the previous operator.
  2. The customer is required to hold a government approved identity card, which works as an address proof. Customers can submit their Aadhaar Card, Driving License, Passport or Election ID Card.
  3. If you are a post paid customer with your existing telecom provider, you shall have to clear all the pending dues of any sort – unbilled amount, billed amount, yearly subscription charges etc. I strongly recommend you to shift to a prepaid plan before making a port request, which will forbid the telecom companies charging you extra and creating a problem in the process.
  4. Lastly, the customer must have the access to the previous SIM card. Lost SIM cards, damaged SIM cards etc. are not eligible for Mobile Number Portability (MNP).

How to apply for MNP:

  1. Firstly, you must have already done a thorough research of the cellular providers which operate in your area. The factors that you should consider before making a choice between two or more providers is the call rates, SMS charges, 3G & 4G internet charges and the network coverage in the areas where you tend to spend your most time, like home and office.
  2. Send an SMS from your existing mobile SIM, writing “PORT” and send it to 1900, which is a free of cost service but in some cases nominal SMS charges may be applied.
  3. You’ll get a Unique Porting Code (UPC) which is an eight-digit code and is communicated over a centralized MNP server. The code will be valid for about 15 days, in most cases and the complete process will have to be completed in this period itself. Please note that in case you are not prepared for the process and the 15 days period is over, you’ll have to repeat the Step 2 again.
  4. With the UPC code in your hand, you are requested to visit the service center of the provider you wish to port into. You will have to obtain the Customer Acquisition Form (CAF) & a Porting Form from their office, at a maximum charge of Rs. 19. After filling in all the required documents, you might have to attach a government ID proof and your photograph, so make sure to carry them.
  5. After a period of about 1-2 days (7 days maximum), your SIM services will start operating on the new telecom company with whom you enrolled for the MNP.

Hope this was an easy step-by-step guide which helped you in porting your number to your desired company. There are also many on-going offers like Reliance Jio offering a month of unlimited data and Airtel offering 30 days of free A2A calling, so make sure to include this in your research while you plan to choose your new company.
