Work through a mixed Dominican Republic contact list: isolate +1 809/829/849 numbers, prevent spreadsheet damage, run WS Activity, and return dated results to the CRM without guessing.
Dominican Republic telephone records are often swept into a generic “US +1” bucket. The country participates in the North American Numbering Plan, but its identifiers are 809, 829 and 849 after +1. This hands-on Dominican Republic WhatsApp activity workflow follows a messy three-source CRM export from normalization through controlled result import.
Format checkpoint: the international number contains +1, one of the three Dominican area codes, and a seven-digit subscriber number. The + sign is not counted as a digit. A bare +1 is not enough to classify a record as Dominican.
The scenario: three sources, four incompatible notations
Imagine a service company combining a Santo Domingo store export, a Santiago team sheet and an online support form. One system writes (809) XXX-XXXX, another stores 1 829 XXX XXXX, and the form contains both +1 849 values and unrelated +1 territories. The objective is to review recent activity among the company’s own customers, not to estimate nationwide WhatsApp adoption.
| Input source | Typical notation | Main control risk |
|---|---|---|
| Store A | (809) XXX-XXXX | International country code is absent |
| Store B | 1-829-XXX-XXXX | Structure is present but the + sign is missing |
| Online form | +1 849 XXX XXXX | Good shape, yet other NANP areas may be mixed in |
| Legacy CRM | 809XXXXXXX or 001809… | Dialling prefixes and text formats are inconsistent |
Use the three area codes as an inclusion rule
The North American Numbering Plan Administrator’s country and territory map lists 809, 829 and 849 for the Dominican Republic. The International Telecommunication Union also lists the country under +1 809, +1 829 and +1 849. Each area code is followed by a seven-digit subscriber number.
The codes share the same national market. They are not age, province, language or income labels. Their role in this job is to exclude other +1 regions and validate total length before screening.
Normalize row by row rather than with one global replacement
Remove spaces, brackets, hyphens and tab characters first. Then convert an international access form such as 001 809… into +1 809…. Add +1 to a ten-digit 809, 829 or 849 value only when the source column is documented as Dominican. Route any other area code after +1 to a separate NANP queue.
| Raw representation | Normalized decision | Why |
|---|---|---|
| (809) XXX-XXXX | +1 809 XXX XXXX | The source is known and the ten-digit structure is complete |
| 1 829 XXX XXXX | +1 829 XXX XXXX | Add the international + marker |
| 001 849 XXX XXXX | +1 849 XXX XXXX | Replace the outbound access prefix with + |
| +1 787 XXX XXXX | Remove from this cohort | It is another +1 numbering area |
| 809XXXXXX | Review | The record is short; never manufacture a missing digit |
Prevent spreadsheet conversion from changing the identifier
A phone number is an identifier, not a quantity. When +1809… is stored as a numeric value, spreadsheet software may remove the plus sign or display scientific notation. Set the working column to text before import. If the underlying last digits were already rounded, changing the cell format cannot recover them; return to the original CRM export.
Keep the normalized column in the workbook for matching, then create a separate TXT file with one telephone number per line. CSV, XLSX and multi-column files containing customer names are not valid number-task inputs.
Run WS Activity and preserve all returned fields
Select WS Activity in the AppShai WhatsApp Number Checker and submit the cleaned TXT list. The downloaded Excel file contains phone number, activity time, activity days and WhatsApp mapped phone number. Import all four into a staging table before deciding which fields belong in the operational CRM view.
- Archive the original CRM snapshot.
- Create normalized-number and exception-reason columns.
- Deduplicate by the normalized value and export TXT.
- Run WS Activity and record the execution date.
- Left-join the Excel result to a copy of the CRM.
- Send unmatched inputs and duplicate mappings to review.
Keep raw time and display time as separate columns
Retain the returned activity time exactly as delivered, together with its documented time convention. A second display field can be converted for a team operating in Santo Domingo. Never overwrite the source timestamp, because a colleague in another time zone may otherwise assign the same event to a different calendar day.
| Field | Storage rule | Purpose |
|---|---|---|
| Raw activity time | Preserve without conversion | Trace the service output |
| Activity days | Keep the exported value | Coarse sorting and segmentation |
| Local display time | Calculate under a documented rule | Operational viewing by the local team |
| Job date | Write once for the entire batch | Measure how old the observation has become |
An unavailable status is not a silent customer
WhatsApp says that last-seen and online visibility can be affected by privacy choices, whether people have previously chatted or saved one another, blocking and temporary connectivity. Read the platform’s official last-seen explanation before converting missing observations into business labels.
Segment explicit timestamps under thresholds fixed before analysis. Keep unavailable values in their own group. A support team can then combine the platform observation with orders, cases and consent records instead of interpreting a blank cell as intentional non-response.
A review matrix for the joined data
| Number quality | Activity evidence | Controlled status | Next action |
|---|---|---|---|
| Valid | Inside the recent window | Recent and interpretable | Provide service within the existing permission scope |
| Valid | Older timestamp | Historic activity | Consider the current customer relationship; do not auto-reactivate |
| Valid | Unavailable | Unknown | Preserve uncertainty rather than assigning inactivity |
| Invalid or unexplained | Any value | Data exception | Repair the source record first |
Measure the pipeline, not just the most flattering percentage
A higher “recent” share may result from a fresher store export, stronger deduplication or a changed time threshold. A meaningful run summary records the submitted rows, format-passing rows, normalized unique numbers, matched outputs, unknown observations and count in each predeclared band.
Compare runs only when those definitions remain stable. The 809/829/849 rule establishes which records belong to the Dominican cohort; the job date and customer relationship establish whether the activity evidence is actionable. Together they turn a mixed +1 spreadsheet into an auditable service queue.
