You can add codes to a batch at any time, including a batch that offers already use. Existing codes keep working while new ones are added.

​
Before you start

Add codes is available when the batch is Ready or In Use and no other add is still running. It is greyed out, with the reason shown, when:
  • the batch is still preparing,
  • the batch has an error, or
  • a previous add is still in progress. Only one add can run at a time.
The button is on the Settings and Codes in Batch tabs. It is not on the Linked Offers tab, where Create offer takes its place. If you have unsaved changes on the Settings tab, save or discard them first.

​
Add codes

  1. Open the batch and select Add codes.
  2. Choose how to add them:
    • Manual: paste codes (up to 1,000) or upload a CSV (up to 100,000), with the same rules as when creating a batch.
    • Generated codes: set how many codes to add, up to 100,000 at a time, and review the generation settings. Sample codes show what to expect. To add more, add codes again.
  3. Leave Notify me after codes are added on if you want an email.
  4. Confirm.
For a very large batch with restrictive settings, generating more codes may be unavailable. The page says so and suggests uploading a CSV instead.

​
Follow the progress

The batch shows Adding codes… while the new codes are created in Shopify. Counts are relative to this add. Adding 500 codes to a batch that already has 10,000 reads “200 of 500 added”, not “10,200 of 10,500”. The batch stays usable throughout. When the add finishes, the Codes total updates and the add appears in the batch’s Timeline with how many codes were added. If Shopify refused some of the codes, the timeline entry links to them.
