# How to Add Voucher Codes
> Stock the reward codes your first campaign needs so Mention Me can fulfil referrer and referee rewards at launch.
The **Add voucher codes** step stocks the codes your campaign will issue as rewards. It sits on the launch checklist after you [prepare to launch](/knowledge-app/onboarding/prepare-to-launch). You cannot upload vouchers until that checklist is open.
On the [Onboarding Hub](/knowledge-app/onboarding/overview), click **Add
voucher codes**. Mention Me opens the campaign that needs vouchers on the
Rewards section, or the campaigns list if more than one applies.
In Rewards, use the **Referrer** or **Referee** list on the left to open
the reward that uses uploaded codes. A **Voucher stock** card appears next
to that reward's setup.
Click **Manage stock**, then **Upload new vouchers**. Keep enough stock for
the first days after launch. A campaign whose batch runs dry cannot fulfil
its promise.
If your rewards are fulfilled another way, for example Shopify or reward
automation, this step can show as **Not needed**. You can still open it to
confirm.
**Activate your first campaign** stays locked until this step is complete or marked not needed, along with drafting the campaign and setting up tracking.
For how rewards and batches work, see [Rewards](/knowledge-app/referral/campaigns/brand-referral/rewards).
