import { Callout } from "zudoku/ui/Callout"; # Data protection and transmitted data This page describes which address data 365 business Address Validation transmits to which service for validation and for prediction. ## Address validation For address validation, 365 business Address Validation calls the validation service of the 365 business API. Only the fields of the address being checked are transmitted: | Field | Transmitted | |---|---| | **Address** | always | | **Address 2** | if filled | | **Post Code** | if filled | | **City** | always | | **Country/Region Code** | always; if the field is empty, 365 business Address Validation transmits the country code of the company | Name, phone number, tax number, and other fields of the record are not transmitted to the validation service. ## Address prediction For address prediction, while you type, 365 business Address Validation transmits the text already entered in the **Name** or **Address** field together with a session token to the map service of the 365 business API. The session token groups the individual requests of one entry into a single billing unit, but does not contain any address or customer data. Once you select a suggestion, 365 business Address Validation then retrieves the full address data for that suggestion from the same service. Address prediction transmits only the text you actually enter into the **Name** or **Address** field. No other fields of the record are read or transmitted for this. ## Storing the result 365 business Address Validation stores checked addresses, and addresses taken over through address prediction, in the [address directory](address-data-directory.mdx) within your company in Microsoft Dynamics 365 Business Central, so the same address does not have to be transmitted to a service again. ## See also - [How address validation works](how-validation-works.mdx) - [Address directory](address-data-directory.mdx) - [Address validation and address prediction](validation-and-prediction.mdx)
