After we complete the phone number status check, will automatically be divided results into active package, invalid package and risk package for you to download.

(1) Active number package: Active number package (2) Invalid package: Phone number and shutdown number that have appeared in the past month (3) Risk package: shut down or no voice service for a long time and users who are easy to complain.

The error is affirmative, for example: network timeout, operator string code, mobile phone number protected, blacklist and virtual card are uncontrollable factors.

We are calling the operator's interface for the query, the speed is 1.5ms / bar, the expected 100,000 mobile phone number status check time in about 3 minutes.

We are calling the operator's interface query, theoretically the accuracy can achieve very high and high.Because the operator gives the query price is more expensive, so there is a month of retained data in our database to query, because of the timeliness problem, there may be a certain misjudgment, but the mobile phone number you detect, every mobile phone number we have a query.The query result of Phone number has been recorded as Phone number in nearly a month.

Each data will be query through the operator data interface, but due to the operator interface cost, our system has a month of database storage, to ensure that the number you screened has the real operator state within a month, such as the data appears in the empty package, there must be a shutdown or Phone number within a month; if it is real, there must be balance and traffic use more than 30M in a month, some data will be shutdown, or the unexpected shutdown, including the operator interface return to the package, so there will be a certain error.
