Why is my number port being rejected
This is not an exhaustive list but a common error list. Rejections mean extra costs on top of the port, and we would like to avoid that where possible.
Incorrect postcode
Make sure this is the exact postcode from your current bill. If your business has moved location, the address associated with your number can often be the address where the number was first created. Be sure to check the address on your bill. You can contact BT to check that their records are up to date if in doubt.
Incorrect Main Billing Number (MBN)
The MBN is listed on the bill from your current provider.
Wrong signatory
If you are a reseller, make sure that your customer signs the Customer Letter of Authority (CLoA). This is to prevent people from taking over numbers without permission.
Multi-line not single-line
Your current provider should be able to tell you this information. If not, or you are unsure then we would advise a 'Pre-Validation Request'. See the section below on 'Pre-Validation Request'. As general guidance, Multi-line tends to be associated with ISDN.
Missing numbers
This will be for Multiline numbers. Numbers can have single or multiple associated numbers that must be ported along with the Main Billing Number. They can also include ranges of direct dial numbers (DDIs).
The number has been ported before
A number may have changed ownership from one provider to another, e.g. BT to Talk Talk. If this has happened, then we must submit what's called a 'subsequent port'. Please advise on the CLoA.
BT Redcare alarm is active
We do ask this question in our initial request but the customer may be unaware or forget if there is an alarm system on the line.
No service on the number
The number needs to be in service to be ported.
