Article summary
Even after an Eritrea +291 Full Format pilot passes, gender and age fields require separate coverage, unknown, purpose and fairness acceptance.
Passing format and count acceptance in an Eritrea +291 Full Format task does not make its gender and age fields automatically acceptable. Base columns may be stable while profile columns remain poorly covered, ambiguous or unnecessary.
Split acceptance into two tickets
| Ticket | Main checks | Can it replace the other? |
|---|---|---|
| Task integrity | Rows, format and schema | No |
| Profile validity | Coverage, unknowns, purpose and fairness | No |
Measure profile coverage first
Build a funnel from original submission, format-processable, task-returned and profile-usable counts. Do not calculate attractive percentages only within visible rows.
Confirm what each field actually means
The field name must distinguish an observation, age band and other state, with observed_at and unknown. Never present it as a verified personal fact.
Run a new purpose test
If the business goal is number cleaning or registration checking, age and gender should not enter CRM merely because Full Format returned them. Every column proves its own necessity.
Inspect differences between sources
Compare profile-usable and unknown rates by acquisition channel. Concentrated missingness suggests a source-biased sample that cannot represent all +291 customers.
Reduce exposure from the TXT stage
The execution file contains one phone per line and no names or internal profiles. After Excel returns, only fields passing the second ticket may enter a controlled analysis area.
Prohibit high-risk uses
Profile observations do not support identity authentication, pricing, eligibility, service denial or sensitive-group inference. Permission, explicit interest and actual interaction are better marketing evidence.
Record the decision not to import
When a field fails, keep the reason, sample, owner and review date. Deleting or isolating it is quality control rather than wasted output.
How the two Eritrea pages complement each other
The Full Format article asks whether a pilot may scale; this page asks whether profile columns may enter analysis. They share country context but resolve different decisions.
