When you launch social ads globally, launchWhen attracting traffic to the WhatsApp private domain or making batch outbound calls, the most feared problem is not "no customers" but "not being able to send out calls."
After importing mobile phone numbers, many teams found that messages failed to be sent, accounts were frequently restricted, connection rates were low, and social platforms could not be registered. The root cause of the problem is often:The number itself is not compliant, inactive, and unreal.
These problems cannot be identified by just relying on the naked eye and format judgment.Operator number detection, especially withBatch testing function with multi-country coverage, has become the infrastructure for social contact.
2. What exactly is screened for in batch screening? Three key dimensions should be clear
If you want to screen accurately and use it stably, you must focus on the following three points:
1. Format legality
Many international number formats look like"Yes", but actually does not comply with the local operator's encoding rules. For example:
lMexico, Argentina and other countries may have overlapping area codes or missing country codes.
lUsers from the Philippines and India can easily fill in theLocal writing starting with "0" affects system recognition
lOperator segments in many European countries are updated frequently, and the old number format has been obsolete.
Through operator number detection, the system will identify these erroneous structures and eliminate them to improve cleaning efficiency.
2. Attribution and type identification
Operator affiliation not only affects delivery strategy, but alsoQuality of "number":
lWhether it is an entitySIM card (physical operator), suitable for social registration and delivery?
lWhether it is a virtual operator (The temporary number provided by VoIP is not suitable for services such as WhatsApp?
lDoes it belong to a high-risk number range, such as a number area with frequent complaints and abnormal number bans?
Attribution identification is not a basic function, but a necessary condition for efficient delivery. It is recommended to retain this field for further marking.
3. Real-time status judgment
It is not enough that the format is correct. It must be combined with status detection to determine whether the number is"can be used":
lIs it active?
lHas it been logged out or shut down?
lHave you been socially active recently?
It is recommended to access this kind of informationOperator number detectionAPI interfaceTo achieve automated judgment, especially when the number is tens of thousands, the cost of manual judgment is extremely high.
3. Are the testing standards in different countries consistent?
Inconsistent.
There are obvious differences between countries in terms of number length, operator allocation, and country code writing. For example:
lUS number fixed10 digits, country code + 1, clear number segment distribution pattern
lIndian number format is easy to mess up,+91 is used interchangeably with the beginning of local 0
lThere are multiple virtual operators in France, Spain and other European countries and must be eliminated
lThe number segments in Latin American countries overlap seriously, and real-time status judgment is needed to determine the authenticity.
Therefore, a batch screening system must haveMulti-national structure identification capabilities, the format cannot be determined solely by regular expressions.
4. How to operate a complete batch inspection process?
Step One: Prepare the Cleaning List
Make sure the number is complete and the format is as international as possible (e.g.+44, +1, +33), unified encoding to avoid illegal characters.
Step 2: Import the detection system
Use supportInternational carrier number detectionplatform (such as Digital Planet), uploadExcel or CSV file, you can start cleaning.
Step 3: Select detection type
Usually the system will provide two methods:
lConsole operation: Results will be available immediately after uploading, suitable for temporary tasks or small and medium-sized teams
lAPI interface call: Automatic docking system,CRM, data platform, realize batch automatic cleaning and warehousing marking
For high-frequency use, it is recommended to connectAPI interface saves manpower and time costs.
Step 4: View the result fields
Focus on the following return fields:
lIs the format correct?
lCountry and operator affiliation
lIs the status"Active/Logged out/Unknown"
lWhether it is a virtual operator (VoIP)
You can perform secondary screening based on these fields to retain only high-quality numbers for social contact.
5. How do the usage results affect the social advertising effect?
If what you do isWhatsApp group sending, Facebook advertising lead conversion, Telegram private domain fissionFor other businesses, the results of batch testing can directly determine the conversion efficiency:
lAfter eliminating invalid numbers, the sending success rate increasesMore than 30%
lWhatsApp registration failure rate drops by 50%, reducing account risks
lSave on manual agents for outbound call team20%, avoid dialing empty numbers
lSocial fission is more stable and the user pool is more real and usable
Many teams have eliminated an entire batch of low-quality numbers through one screening, and the cost of social recruitment has dropped fromUSD 0.3 dropped to 0.18.
Conclusion: Number screening is not an additional allocation, but a necessary option to reduce costs and improve efficiency.
If you are still importing untested international numbers to directly reach customers, it will not save time but amplify losses.
No matter which country you are doing social operations in, you should do a good job of checking the operator number on the front end, especially for multinational projects, and you cannot ignore this link. Test it once and use it for the entire cycle.
