Your own business details, always. Branvas is a private-label provider and does not issue sellers a warehouse address; our details must not appear in your store settings, on packaging, or on shipping/return labels.
Use your own business or mailing address in address, origin, and return-address fields (they describe your business, not our facilities).
Use your own branded support email in customer-facing contact fields, never [email protected], which is for you to reach us.
Returns don't come to you: Branvas issues a return address based on the customer's location, with no Branvas information on it.
TikTok Shop asks for a warehouse and return address at setup; the same rule applies, so use your own details. Our recommendation: use TikTok as a marketing channel and send buyers to your Shopify store, where Branvas fulfills as normal and you avoid TikTok's commissions.
If a channel's validation rejects your details, email [email protected] with a screenshot.
