Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This batch checker accepts mainland China mobile numbers and displays the lookup response: portability status, original and current operator, area, and virtual-operator indicator when supplied. Some fields may be unknown or absent, and provider text may remain in Chinese.
Number portability means changing the contracted mobile operator while keeping the number. China’s Ministry of Industry and Information Technology defines it this way and requires operators to publish their application conditions and process. Read the Chinese portability service rule (effective December 1, 2019; checked October 4, 2026).
These are lookup fields, not decisions about eligibility, identity, ownership, or contract terms.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Use cases
See how the tool fits into real work and everyday tasks.
A team responsible for a mainland China list can check permitted numbers and compare returned operator fields with its own records. Confirm discrepancies with an appropriate carrier before updating records.
An authorized support worker can inspect available fields as a preliminary reference when a user asks about a possible port. The subscriber should confirm service details with the current carrier.
Q&A
Find concise answers to common questions and confusing cases.
No. The input accepts 11-digit mainland China mobile-number format, without a country code, spaces, or punctuation.
No. It is a lookup status, not an eligibility decision. Ask the current carrier about current conditions and the official process.
A field may be absent or unmapped, producing an unknown fallback. Provider-supplied text can remain in Chinese even though the controls are English.
Notes
Review scope, result limitations, and important precautions before use.
This lookup is for mainland China numbers. Its upstream source, coverage, refresh schedule, retention period, and completeness are unverified; a result is not guaranteed current or universal. A valid format is not proof of an active number, identity, ownership, or portability eligibility.
Submit only numbers you are authorized to check and need for the task. Processing uses a remote lookup service. Avoid unrelated personal details and limit access to exported workbooks. Confirm the page’s displayed price before starting.
