Payouts are issued from the country of your Stripe connected account. If your external bank account is in the same country and currency, the payout typically appears as a domestic transfer. If your bank is in a different country or you’re paid in a different currency (for example, via alternative currency payouts), it may appear as an international transfer.
To gauge what to expect, compare the connected account’s country and currency with your external bank account’s country and currency—when they match, expect domestic; when they don’t, expect international.
