# Lookup - by Tax Id
source: https://developer.mastercard.com/merchant-identifier/documentation/tutorials-and-guides/lookup-by-tax-id/index.md

The client has raw data which includes Tax Id, but the client is unable to identify other merchant details and attributes about the merchant in the transaction. In this example we will query for merchants matching the tax id of '15065786007458' in the country of 'BRA'
Note: Tax Id lookup is currently available for merchants in Brazil only. To inquire about other geographies, please reach out to your Mastercard representative. Tip: The Tax Id used in this example is available in the sandbox.
