# Overview

> A series is a counter with formatting details used to generate sequential codes.

## Model

A "Series" object contains the following fields:

| Property | Type | Description |
| - | - | - |
| id | uuid | Unique identifier (UUID). |
| name | string | Human name to help identify the series. |
| prefix | string | Text to place before a generated code. |
| padding | integer | Width of the code's number, with zero padding. |
| suffix | string | Text added after the series' number. |
| sigs | array of string | If the series was created with any signatures, they'll be here. |
| created\_at | date-time | Timestamp of the series' creation. |
| updated\_at | date-time | Timestamp of the last update. |

A series object may look like:

```json theme={"system"}
{
  "id": "835bb1ca-e7c4-41e6-9e88-464de54cc08e",
  "name": "Testing",
  "prefix": "TEST1",
  "padding": 5,
  "suffix": "-2022",
  "created_at": "2022-03-03T22:18:50Z",
  "updated_at": "2022-03-03T22:18:50Z"
}
```

With a start of `1`, the first entry added to that series generates the code `TEST100001-2022`. The series object does not track its position; to find the latest code, [list the series entries](/api-ref/sequences/entries/fetch-all-series-entries), which are returned newest first.
