    Cell Phone Number Service:Integration overview

    Last Updated:Jun 08, 2026

    Integrate Cell Phone Number Service programmatically to query phone number status, simplifying operations and reducing management costs.

    OpenAPI overview

    The Alibaba Cloud OpenAPI portal provides API search, documentation, online debugging, SDK downloads, code samples, error diagnostics, and call statistics. Use it to invoke OpenAPIs, view request and response details, and generate SDK code examples. What is OpenAPI.

    Version guide

    Cell Phone Number Service provides OpenAPIs for phone number status queries, mobile number portability checks, number location lookups, and personal information verification.

    Note

    Alibaba Cloud uses version numbers to manage API lists for major cloud product versions.

    For example, Cell Phone Number Service supports API version 2020-02-17. This is an API version identifier, not a calendar date. It does not mean the APIs have remained unchanged since that date.
