Address Mismatch - Error Code E1


Taylor Murphy


You may see this error displayed as the error code of E1 and/or with the message 'Address Mismatch'.

What does this mean?

This means that the address submitted on the order does not match the address on the losing carrier’s Customer Service Record (CSR).  Most carriers will require the service address be presented on the order, rather than the billing address. 

How do I resolve it?

Bandwidth will attempt to pull a CSR on your behalf to assist in resolving this rejection.  If this is unsuccessful, and/or to speed up the process, the end user may need to contact their current provider to pull the current name on the CSR. 

Important Information:

Although what is provided on your end user's bill copy, it does not mean that the information provided there is the same as what is on their CSR.  These are two separate documents and many times, the information is not the same. Carriers require the Service Address for the lines porting, instead of the Billing Address. Porting requests most often need to be submitted with the information that is contained in the CSR, not the bill copy.  The exception to this rule can be for toll free or wireless ports, as those usually require the billing address.
