# CSV import This is a sample of the CSV format and some sample data: ``` customerid;firstname;lastname;telephonenumber;emailaddress; 1231235435;test;dfgdfg;+31612312311;test@test.com; 1231235435;test;dfgdfg;+31612312311;test@test.com; ``` Please copy the first row and use it as the first row of your CSV file. All telephone numbers **must** be in valid E.164 international format, example: +31612312311. {% hint style="info" %} Omnidesk will provide a secure SFTP account if asked so you can safely transfer the CSV to us. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
