Convert Ecuadorian 09 mobile records to +593 9 and audit WhatsApp registration results through batch reconciliation and false-negative diagnosis.
An Ecuador WhatsApp registration project should not be evaluated from a final yes/no column alone. The +593 mobile structure, domestic trunk zero, spaces in legacy files and duplicated records can make a formatting defect look like a registration result. Treat each run as an auditable experiment: preserve its input rule, exception count and observation date.
Understand the +593 mobile structure first
Ecuadorian mobile records commonly begin with domestic 09 notation. International normalization removes the domestic trunk zero and produces +593 9…. ITU documentation of the numbering change records the +593 country code and a 9X mobile network-code structure. Legacy lists should therefore be evaluated under a current, versioned rule rather than an old length assumption.
Keep three input forms distinct
| Source form | Transformation concept | Main risk |
|---|---|---|
| Domestic 09… | With Ecuador evidence, transform to +593 9… | Retaining the zero twice |
| International +593 9… | Remove separators and validate | Legacy range or truncation |
| 9… without a country code | Require a supporting country field | Misclassification as another country |
Create an input ledger for every run
Record source_file, source_row_count, normalized_count, duplicate_count, exception_count, rule_version and file_hash. When an outcome looks unusual, the team can isolate a source, transformation or task issue instead of uploading a new file that cannot be reproduced.
Place the official evidence beside the rule
The International Telecommunication Union’s notice on the Ecuador +593 mobile numbering change records the expansion of the network code to two digits by adding 9. The citation makes the historical basis inspectable. A production rule must still include its effective version and monitor later notices from the responsible authority.
Model four result states
| State | Meaning | Next action |
|---|---|---|
| registered | The task returned registration in this run | Store the date; do not infer permission |
| not_registered | The task explicitly returned a negative result | Interpret with input-quality evidence |
| unknown | No definitive conclusion was produced | Keep unknown; do not rewrite as negative |
| error | A format or task exception occurred | Correct the cause and rerun only that subset |
The AppShai task flow
Export validated phones as UTF-8 TXT, one per line, without customer names, addresses, orders or notes. AppShai accepts TXT only. Select WS Registration or WS Fast Registration, complete the task and download the corresponding Excel fields such as phone and registration result.
How to detect formatting-driven false negatives
- Compare results by original input form.
- Inspect records that retained a zero after +593.
- Check whether one source file contains widespread truncation.
- Include a small known sample as a pipeline control.
- Repair only the faulty path and assign a new batch_id.
The control is not an accuracy guarantee. It tests whether the data pipeline contains a systematic defect.
Separate registration, activity and permission
Registered is a dated platform observation. Recent activity requires the corresponding WS Activity task. Permission comes from a form, contract, support interaction or subscription system. A CRM with one whatsapp_status field will eventually mix the concepts; use registration_state, activity_observation and permission_state instead.
When a targeted recheck is justified
Recheck after a rule-version change, correction of a defective source, a previous unknown/error result, or a genuine business need for a new observation. Do not repeatedly run the same correct input merely to reduce the negative count. Account state may change, but repetitions without dates and reasons only generate noise.
A useful Ecuador +593 report can state which phones passed validation, which were quarantined, how many records occupy each of the four result states and which batch supports every conclusion. That auditability has more operational value than a spreadsheet containing only yes and no.
