# How to share promo codes on Instagram

Instagram gives a code three usable surfaces: text in captions and Stories, the link sticker in Stories, and your bio. Caption links are not tappable for almost everyone, and a bio holds 150 characters, so the reliable system is one bio link to a page that holds every code, plus the code itself written in the content where you mention it.

## What each Instagram surface can and cannot do

| Surface | Codes | Links | Notes |
| --- | --- | --- | --- |
| Bio | As text, cramped | Up to 5 external links; only the first shows | 150-character limit including the codes you paste in |
| Captions and comments | As text | Not clickable (a small Meta Verified caption-link test exists; do not rely on it) | Followers must retype or memorize the code |
| Stories | As text overlay | Link sticker, available to accounts in good standing | Disappears in 24 hours unless highlighted |
| Broadcast channels | As text | Tappable links in channel messages | The one mass-message surface with working links |

## Measuring what Instagram will not show you

Instagram tells you nothing about what happens to a code after you post it. A code page fills that in: views per campaign, taps to the brand, and [copies](/guides/code-copies-vs-link-clicks), which is how you learn whether a Reel actually moved a code or just got watched.
