 ## Bulk Update Campaign TN Relationships
 We do not have a publicly exposed REST endpoint for bulk TN updates. Please see how to import a csv in our [CSP campaign Dashboard UI guide](https://support.bandwidth.com/hc/en-us/articles/5900095168663-How-to-register-a-campaign-for-10DLC).<br/>
 For more info on TNs, please see [Number Management](/docs/numbers/).<br/>
