Porting FAQ's

Why was my UAN number rejected?

Following are some reasons why a UAN number and subsequently a whole port might be rejected. These reasons are also mentioned throughout the procedure and can be avoided with careful preparation and communication with the current provider before submitting the port request.

  • Incorrect bill information
  • Data entry error
  • Bill shows a different carrier against the porting database due to WLR (wholesale line rental)

How do I select port request date?

The requested port date should be at least 48 hours from the time of submitting the port request. It should not be set for the very beginning or end of a porting window (or business day); especially not for a Friday at 4.30pm. The porting window is each day Monday to Friday 9am to 4.30pm. Porting requests that are submitted on a Friday will be processed the following week. The current provider requires 2 hours to respond to the request and at least 4 hours to authorise and confirm the porting date.

Is it possible to port all numbers?

Most numbers are available for porting, but depending on the type of number prefix, it might not be possible to port some numbers due to agreements between telecom providers. Check with our porting desk to see if the numbers can be ported across to our network.

IP Telecom has experience with most telecom providers and we should be able to determine if your number can be po rted.

What does number porting mean?

Porting a number means taking an existing phone number from one provider and transferring it to another.

What happens if we need to move our number back to the original operator?

If 24 hours has passed, you must request the old carrier to port the number back to them. This involves a completely new port request and can take up to 10 working days.


This situation should only come up if you have completed the porting request without understanding the implications of moving your numbers. If you are uncertain at any stage in the porting process, contact our porting desk for advice before submitting a porting request.

How long does it generally take to move our number?

Porting Irish numbers should take approximately 24/48 hours. Porting UK numbers can take a minimum of 10 working days or more.

For the porting of all other international numbers depends on the regulator in the country we are porting from but allow a minimum of 10 working days.

What is a Letter of Authorisation and why do we need it?

A Letter of Authorisation (LOA) is a document that allows IP Telecom to request your numbers from your existing provider on your behalf.

Our main number is used for DSL, can we port this number?

It is possible to port this number to IP Telecom but it will result in the DSL being ceased. IP Telecom can assist in maintaining your broadband service and can facilitate you keeping your number.

My port request failed, how can we correct that?

Depending on the rejection, you might have to go back to your current provider to request more information.

Ports will reject for any of the following reasons:
