### iOS bundle ID

It's a unique app identifier for iOS. It will be used when you upload ipa file to the AppStore.

Example : <mark style="color:orange;">com.twinr.Ecommercely</mark>

Please refer [this](/publish-apps/publishing-to-the-apple-app-store/create-your-apple-bundle-id.md) document to create new iOS bundle ID if you don't have one.

**Next Steps:**

1.) Go to <https://appstoreconnect.apple.com/> and login to your account.

2.) Click on <mark style="color:green;">Users and Access</mark> option.
