+## Retrieve a wallet address from an inbox ID
+
+An XMTP inbox ID can have an array of addresses associated with it. To retrieve an address from an inbox ID, use the `inboxState` method. This retrieves the current state of the inbox, which includes the primary address associated with it.
+
+### Best practices
+
+When displaying an address for an inbox ID, consider these best practices:
+
+- For 1:1 chats: Display the primary address or name associated with the inbox ID.
+- For group chats: Display the name of the group, or enable users to choose the one address they want to display from the associated addresses.
+
+Displaying multiple addresses for an inbox ID can create a misleading UX for users. For example, it could make a 1:1 chat appear to have more than two participants.
