Why number porting requests can be rejected

Number porting is the process of moving your existing phone number from one provider to another. It should be straightforward, but ports can be rejected if the information supplied doesn’t match what the current provider has on record.

Below is a short guide to help you understand the most common reasons for rejection and what you can do next.

Common reasons a number port may be rejected

  1. Incorrect postcode

The postcode must match exactly what appears on your current bill. Even if you’ve moved, the number may still be registered to the original installation address

  1. Incorrect Main Billing Number (the 'MBN')

The MBN (your phone number) must match the number listed on your existing provider’s bill

  1. Wrong signatory

The porting request must be signed by the main account holder

  1. Single-line vs. multi-line mismatch

If the number is part of a multi-line or ISDN range, all associated numbers may need to be included

  1. Number previously ported

Sometimes if your phone number has been moved to another provider before, it may require a “subsequent port” process

  1. Security or alarm services on the line

For example, BT Redcare alarms can block a port until removed

  1. No active service

The number must be live and in service to be ported

  1. Insufficient information or mismatched details

Any discrepancy between the current porting request and the existing providers records can trigger a rejection

  1. Not enough notice

Some port requests require a minimum notice period

Can you reapply after a rejection?

Yes. In most cases, once the incorrect or missing information is corrected, the port can be resubmitted. Often, checking your latest bill or confirming details with your current provider resolves the issue quickly. If needed, a pre-validation check can also help ensure the information matches what the losing provider has on record.
