# 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.

Omnidesk will provide a secure SFTP account if asked so you can safely transfer the CSV to us.
