Ways To Prevent Delays/Rejections When Porting TN's

Last Updated: Nov 08, 2016 09:58PM EST

Porting phone numbers between service providers is a delicate and detail-sensitive process. Your current service provider does not want to lose you as a customer and will enforce very specific requirements for a successful port request to be completed. The below information will enable you to prepare for these requirements and avoid delays.


Customer Service Record (CSR)

The Customer Service Record (CSR) will provide all of the information necessary in order to fill out the Letter of Authorization. Acquiring the CSR from the losing provider will ensure the best accuracy when filling out the Letter of Authorization.

Letter of Authorization Accuracy

A Letter of Authorization (LOA) gives Sharpen the right to transfer numbers from your current provider to Sharpen. If any information on this document is inaccurate, the transfer will be rejected by your current service provider. For this reason, one Letter of Authorization is required for each individual account.  For example, if you have 2 service providers and two accounts with each, you will need 4 Letters of Authorization.

  • Business Name - Exactly as it appears on your phone bill
  • Physical Service Address - This may be different than your billing address and cannot be a PO Box
  • Billing Telephone Number (BTN) - The unique primary phone number for each account
  • Authorized Name - The name of the Authorized Agent on record with your current service provider

Keep Existing Services

Be sure to notify your current provider that you intend to keep all services not being ported to Sharpen including Internet, fax, alarm, gate/elevator phone lines, etc.

Remove Special Features on Numbers

Special features such as remote call forwarding or hunt groups can be reason for rejection by your current service provider. Please notify Sharpen of any special features existing on your account.

DSL on the Line

If you are transferring the phone number associated with your DSL service, your Internet service will be disconnected unless you contact your DSL service provider and select another number to be associated with your DSL service. If this occurs, your Sharpen solution will not work.

Outstanding Orders on the Account

If you have recently made any changes to your account, such as terminating/ordering services or features, this will conflict with our submitted port request. If you think there might be outstanding orders on your account, please contact your current service provider and request that any outstanding orders other than the port request be canceled.

Porting Some, But Not All Numbers on the Account

If there are any numbers on your account that you do not wish to port, your current service provider will ask Sharpen what you would like to do with these numbers. Please inform Sharpen of any numbers on your account that you do not want to transfer and what your intentions are for those numbers.

If you have any questions about this information please contact the Sharpen support team at or by dialing 855.249.3357.
