Article summary
Choose among seven WA/WS services by business question, with real TXT input, Excel fields, acceptance checks and marketing boundaries.
People searching for a WhatsApp Number Checker often imagine one button: upload phones and receive good or bad. AIPUSH actually offers multiple WA/WS tasks. The wrong task does not become right because it exports more columns. Name the business decision first, then choose a route on the service map.
Map entrance: what do you need to know?
- Only observe registration: choose a Registration route.
- Need recent account observation: choose Activity.
- Need a profile-image observation: choose Profile Picture.
- Running controlled aggregate profile research: assess Gender and Age.
- Several fields must arrive from one task: evaluate Full Format.
Choosing among three registration routes
| Service | Returned fields | Selection basis |
|---|---|---|
| WS Registration | Phone, registration observation | Standard registration question |
| WS Fast Registration | Phone, registration observation | Same core output; choose by actual task condition |
| WS High-Precision Registration | Phone, business-account observation, mapped phone | Additional account-relationship observations are necessary |
“Fast” and “high precision” are not marketing-permission levels and must not become absolute accuracy claims.
Activity asks a time-related question
WS Activity may export phone, activity time, active days and mapped WhatsApp phone. Results need checked_at. A recent observation is not necessarily online-now status, purchase intent or willingness to receive marketing.
Profile Picture is a profile observation
WS Profile Picture may return phone, business-account observation, avatar and mapped phone. An avatar null can mean no image, restricted visibility or an observation limit. A visible image does not prove human identity, trust, age or ethnicity.
Where Gender and Age may fit
The task may return phone, age, gender, avatar and mapped phone. It is better suited to aggregate research with minimum cells than individual decisions. Do not use inferred profile data for identity, minor detection, employment, credit, insurance or differential pricing.
Full Format is not the automatic best option
WS Full Format may include activity time, active days, gender, age, avatar, skin-tone observation, avatar type, business-account observation and mapped phone. More fields create more missingness, bias, access and deletion duties. Do not collect columns without a stated use.
Before upload: TXT contains execution data only
AIPUSH accepts TXT with one phone per line. Internally preserve phone_raw, country evidence, exception reason and batch_row. Do not place names, orders, addresses, permission or customer tier in the upload.
After download: Excel passes three gates
- Count gate: input, output, exception and duplicate totals reconcile.
- Meaning gate: unknowns, nulls and field definitions are explicit.
- Join gate: batch_row is unique and mapping conflicts receive human review.
After the gates, append dated observations instead of overwriting all history with one status.
Three boundaries often confused
| Checking result | Does not equal | Determined by |
|---|---|---|
| Registration | Non-empty telecom line | Separate line-status task |
| Activity observation | Permission to contact | Consent and suppression ledger |
| Business account/avatar | Identity and trust | Authoritative verification and human process |
Marketing use passes through permission
Technical reachability does not authorize sending. Verify source, sender, channel, purpose, region, frequency and exit path, and comply with the WhatsApp Business Messaging Policy. An opt-out outranks every new number-checking observation.
Select the smallest sufficient task
Write the decision, list the minimum fields and validate on a sample. If two columns answer the question, do not buy ten. If the business needs permission or order evidence, obtain it from internal systems rather than expecting a checking task to generate it.
Maintaining the guide in 2026
Store task version, field dictionary, checked date, expiry and deletion record. Platforms and observations change, so the article should follow official policy and actual product fields. A changing facts block is not permission to expand capability claims.
The exit from the service map
A good outcome is not the largest group of phones. It is a minimum task selected for a clear decision, Excel that can rejoin safely, unknowns that remain unknown, and permission that was not overwritten by technical fields. That is operational WA/WS Number Checking.
