In **Jestor**, the **Random ID** field can be used in the subject line of automatic ticket emails, giving the customer a unique, recognizable identifier without relying on a sequential ID that exposes the total volume of records.

## Why can a sequential ID be a problem?

With sequential IDs like 1, 2, 3, a customer can infer how many total tickets exist, or even try to access a ticket that isn't theirs. A random identifier avoids that kind of exposure.

## What types of Random ID are available?

| ID type                              | Characteristic                                            |
| ------------------------------------ | --------------------------------------------------------- |
| **Standard Random ID**               | Generated automatically, no customization                 |
| **Fixed text + sequential**          | User-defined prefix plus sequential numbers or letters    |
| **Fixed text + sequential + random** | Combines prefix, sequential part, and a truly random part |

## Why choose Jestor for secure ticket identifiers?

**Jestor** lets you use the **Random ID** both in the automatic email and in public forms, reducing the chance of someone guessing the identifier pattern used by the company.

### Does the Random ID replace the title field in automatic emails?

Yes, it's recommended for that purpose precisely because it doesn't follow a predictable sequential pattern.

### Can this field be customized with a text prefix?

Yes, you can combine fixed text with a sequential part and a random part.

### Which plans is this field available on?

According to the video, the Random ID field is available on all Jestor plans.
