The following address ID fields are available in EZ Exporter's order export:

• billing_address.id
• shipping_address.id
• customer.default_address.id

These ID fields will look something like this: gid://shopify/MailingAddress/4117165007?model_name=Address

If you'd like to export just the number portion of the ID field (i.e. 4117165007 in the above example), you can use a formula like this in the Calculated Fields:

strip_url_query_string({{ billing_address.id }}).split("/")[-1]
