Mauritania +222 WhatsApp List Audit: From Handoff to Excel Acceptance

Direct answer：Freeze and document the original file, assign a stable identifier to every input row, and preserve both the original and normalized values. Report format, mapping, and account-verification outcomes separately; keep unresolved cases as unknown or in review. Before delivery, reconcile every output row to its input and confirm that the data is authorized for the stated use.

A Mauritania +222 list may arrive as TXT, a spreadsheet, or an export containing blank lines, duplicates, inconsistent country-code notation, and extra fields. A dependable WhatsApp-related screening task is not just a column of yes-or-no results. It is a traceable workflow that explains what was received, how each value was handled, what a status means, and which cases still need review. This guide is for teams authorized to process the data. Account states can change, so any verification result should be understood in the context of the method and time of the check.

Start with the handoff record, not the TXT file

Before parsing, record the filename, receipt time, sender or system, stated source, intended purpose, authorization basis, and expected row count. Keep an unmodified, read-only copy of the original. Perform trimming, splitting, prefix handling, or deduplication only on a working copy, and record the rules used. If the final count differs from the input, this record helps identify whether the cause was in the source or a processing step.

Agree on the task’s actual purpose: checking number syntax, screening availability, or performing some other authorized verification. These are different activities and should not be collapsed into a vague label such as “valid.” If the source, purpose, or authorization is unclear, pause and ask the responsible party before importing the list rather than trying to resolve governance questions afterward.

• Record file, source, receipt time, intended use, authorization scope, and expected records.
• Preserve the original; make changes only in a controlled working copy.
• Confirm which fields, tools, retention period, and roles are permitted.

Give every input row a stable position

Assign each original row a record ID or row number that will not change when the data is sorted. Preserve the original text. Count blank lines in the audit record even if they are excluded from later checks. When a row contains multiple numbers, follow a documented splitting rule, create child records, and retain their link to the original parent row. Do not silently combine several values into one result.

Treat +222 as a country-code clue to interpret under the task’s agreed rules, not as proof that a number is valid. Decide how to handle forms such as +222, 222, local notation, spaces, brackets, or leading symbols. Keep the submitted value and normalized value in separate fields. If the length, characters, or code combination cannot be parsed confidently under the agreed rules, mark it for review rather than guessing or filling in missing digits.

• Retain original text, stable row ID, normalized value, and processing notes.
• Document splitting, whitespace handling, and duplicate rules; do not make silent edits.
• Route values that cannot be parsed reliably to review instead of guessing.

Separate number format, code mapping, and account status

“All-format” should mean that the defined input-format families are checked separately. It should not imply a guarantee that every possible notation is covered or promise a particular hit rate. A format result describes whether text fits an agreed number representation. A country-code mapping describes how a rule or system interprets the number. Neither result alone establishes that the number is currently in use or linked to a WhatsApp account.

Use distinct, understandable fields—for example, submitted number, normalized number, format family, parsing status, verification status, check time, and reason code. The verification vocabulary should allow confirmed, not confirmed, unable to determine, and not checked. A service may be unavailable; information may be insufficient; access may be restricted; or a result may be stale. Those conditions can produce an unknown outcome. Unknown is not the same as invalid, and it is not confirmation.

Put disagreements in a conflict table rather than overwriting values. Examples include multiple country-code interpretations, disagreement between a submitted value and its mapped value, or a collision after normalization. Preserve each candidate interpretation and its source. A reviewer with appropriate authority can decide whether more evidence is needed. Until resolved, do not treat a disputed mapping as a basis for automated contact.

• Report syntax, mapping, and account verification as separate outcomes.
• Distinguish unknown, undetermined, not checked, and invalid.
• Keep conflicting values, their sources, and the reviewer’s decision history.

Reconcile the Excel output before acceptance

Use the stable row ID to compare inputs with outputs. Reconcile the original record count, blank-line count, successfully parsed records, review cases, duplicates, conflicts, and final export count. If one source row is split into multiple numbers, report parent-row and child-record counts separately. Explain every difference; do not make totals appear to match by deleting exceptions. A reviewer should be able to follow each exported record back to its original input.

Inspect the spreadsheet’s column names, cell formats, filters, and encoding. Confirm that +222 and other leading symbols have not been dropped, transformed into formulas, or misread as numeric values by spreadsheet software. Sample-check the link between original and exported rows, including blanks and duplicates, against the rules agreed for the task. Record the export version, generation time, owner, and any subsequent edits.

• Reconcile by stable ID and explain each category of count difference.
• Check how +222, leading symbols, long values, blanks, and duplicates display in the sheet.
• Sample-check original values, normalized fields, statuses, and conflict records.

Restrict sensitive data and preserve history as events

A phone number and information about its relationship to a WhatsApp account can be sensitive. Process only what is necessary for the stated purpose and verify that appropriate authorization exists. Do not repurpose the list for undisclosed marketing, profiling, or onward sharing. Limit access by role, and avoid placing full numbers in public tickets, screenshots, or unprotected sharing links. Applicable obligations depend on the relevant rules and organizational policy, so the responsible team should confirm them rather than assume a universal legal conclusion.

Do not overwrite an earlier result with a new one. Append an event that records when processing occurred, who or what performed it, which input and method were used, what status resulted, whether a person reviewed it, and any later correction or deletion. Because account states can change, a timestamped history describes what a particular version said at a particular time; it does not claim the result remains true indefinitely.

• Minimize collected fields, access, export scope, and retention time.
• Attach check time, method description, owner, and review status to results.
• Pause and escalate if authorization is unclear, data is exposed unexpectedly, or fields exceed the approved scope.

FAQ

Does a correctly formatted +222 number prove that it has a WhatsApp account?

No. A format check only indicates that the text matches the rules being applied. Whether an account exists or is reachable requires an appropriate, authorized check at a particular time. If it cannot be established, retain an unknown status.

Why not classify an unknown result as invalid?

Unknown may mean the checking method was unavailable, evidence was insufficient, access was restricted, or the result was stale. None of those conditions proves that a number is invalid. Combining the states can mislead later decisions.

How should a source row containing several numbers be counted?

Keep the source row as a parent record and create linked child records for each number according to a documented splitting rule. Report parent rows and child records separately.

What is the key check before delivering the Excel file?

Match each output to its stable input ID, explain every count difference, and verify that +222, leading symbols, duplicates, blank values, and conflicts were preserved or handled according to the documented rules.

Conclusion

A reliable Mauritania +222 audit depends on traceable inputs, explicit status definitions, visible conflicts, and row-level acceptance—not on treating a format check as proof of an account. Confirm authorization first, process records using stable IDs, and preserve each result as a timestamped event. That makes the handoff easier to review, correct, and control.
