Do Not Call Register Real Time Access (RTA) Washing Service is one of 8 APIs that [ACMA](https://apis.io/providers/acma/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Do Not Call Register, Telemarketing, Compliance, SOAP, and SFTP. The published artifact set on APIs.io includes API documentation, an API reference, and pricing.

The Do Not Call Register is operated by the ACMA under the Do Not Call Register Act 2006. Telemarketers and fax marketers must check ("wash") their contact lists against the register before calling. ACMA documents four submission channels for washing, two of which are programmatic — "Automated Washing Service (AWS/SFTP)" and "Real Time Access (RTA/SOAP)" — alongside manual Quick Wash keying and website file upload. The RTA channel is a ColdFusion SOAP web service whose WSDL is publicly retrievable at https://www.donotcall.gov.au/dncrtelem/rtw/washing.cfc?wsdl and which exposes three operations: GetAccountBalance, WashNumbers and GetWashResult. Calling it requires an industry account and a paid washing subscription (type D or above); the credentials are an Account/Telemarketer ID and passphrase passed in the SOAP body, with an optional wash-only sub-account ID. TLS 1.2 or above is mandatory. ACMA recommends up to 200 numbers per call, a hard ceiling of 500 numbers per payload, and fewer than 5 million numbers per month through this channel. Wash results are returned per number as Y (on the register), N (not on the register) or I (invalid phone number). The AWS/SFTP channel is a batch alternative at sftp.donotcall.gov.au using SSH key authentication with upload/download/archive folders.
