Article summary
Use a provenance-purpose ledger to control admission, fields, retention and opt-out for Latvia +371 WhatsApp Registration.
A Latvia +371 phone should not enter WhatsApp Registration merely because its format looks valid. Every provenance needs a purpose ledger stating why processing occurs, what output may support and when the purpose ends.
Core columns in the purpose ledger
| Column | Question |
|---|---|
| source_id | Where did it come from? |
| purpose | Why check? |
| allowed_action | What may output support? |
| permission_basis | What permits contact? |
| delete_after | When is it cleared? |
Do not execute a source with no purpose
“Possible future marketing” is not specific. Quarantine unknown provenance, opt-out and records beyond the original purpose.
+371 formatting belongs in another table
Preserve phone_raw and log transformation rules. Passing format permits technical checking; it does not replace the purpose ledger.
Use minimum fields for Registration
When only registration is needed, do not add activity, avatar or profile data. TXT contains one phone per line.
Recheck admission when Excel returns
Use batch_row to reconnect purpose and provenance. Append observations only while the ledger remains valid; conflicts enter review.
Registration is not permission
Observed registration cannot create consent, clear opt-out or expand purpose. Suppression fields are read-only to checking.
Organisational responsibility in an EU context
The operating organisation assesses necessity, transparency, access, retention and data-subject rights under its circumstances and seeks qualified advice where needed.
Create a new record for purpose change
A new project must not silently edit old purpose. Add a decision record and expiry while retaining the change trail.
The Latvia acceptance sentence
Every +371 result returns to a current provenance and purpose; output that cannot return does not enter operations.
