# Speed Dial Number Parameters

When you export speed dial numbers, or prepare a file to import them in bulk, the data is stored as a CSV (Comma-Separated Values) file with one row per entry. This page lists each column in that file, whether it must be filled in, and the rules the value has to follow.

:::note
A speed dial number is a short code (up to 4 digits) that a user dials in place of a full phone number. The system looks up the code and places the call to the phone number stored against it, so users do not have to remember or key in the whole number. The Remark column is just a label to help you identify each entry.

## Columns

| Column | Required? | Rules |
|--------|-----------|-------|
| Speed Dial Number | Required | Up to 4 characters. Only digits and the symbols `*` and `#` are permitted. Each value must be unique, no two entries can share the same speed dial number. |
| Phone Number | Required | Up to 31 characters. Digits, letters, and the symbols `(` `)` `.` `-` `+` `*` `#` are permitted. |
| Remark | Optional | Up to 60 characters. |

:::tip
When you fill in an import file, match these column headings and limits exactly. Rows that break a rule, such as a speed dial number longer than four characters or one that duplicates an existing entry, are rejected during import.
