Prepare Nigerian +234 numbers for a WhatsApp Full-Format Check, remove the domestic trunk zero correctly, upload one-number-per-line TXT, and interpret each Excel field without overclaiming.
A Nigeria WhatsApp Full-Format Check begins before any upload: domestic numbers must be normalized to the +234 international format. A common Nigerian mobile number is written nationally with an initial zero. For international use, remove that domestic trunk zero and add +234. For example, 0803 123 4567 becomes +2348031234567.
After formatting, decide whether Full Format is actually necessary. If the only question is WhatsApp registration, WS Registration Check is sufficient. Full Format belongs to a workflow that genuinely requires several supported fields and has already addressed necessity and privacy.
How to normalize Nigerian +234 numbers
The Nigerian Communications Commission’s National Numbering Plan documents local numbering resources. A business should still rely on the source-country field and provenance. Do not assign +234 simply because a prefix looks Nigerian.
| Source value | Suggested TXT value | Change |
|---|---|---|
| 0803 123 4567 | +2348031234567 | Remove the trunk zero and add +234 |
| 2348031234567 | +2348031234567 | Country code exists; add the plus sign |
| +234 803 123 4567 | +2348031234567 | Remove spaces |
| +23408031234567 | Needs correction | Do not retain the national trunk zero after +234 |
These are formatting examples, not customer records. A real check requires lawfully obtained data and a valid current purpose.
Prepare the TXT upload
AppShai currently accepts TXT only, with one phone number on each line. Do not include names, email addresses, customer labels, country names, commas, or a header. Remove spaces, brackets, and hyphens, deduplicate by the full normalized value, and save UTF-8 text.

2347012345678Excel and CSV cannot be uploaded directly. If the source is a spreadsheet, retain the master file and export only the normalized phone column to TXT. Customer ID, provenance, and permission stay inside the company’s controlled system.
Which Excel fields does WS Full Format return?
AppShai’s current WS Full-Format output may include phone number, activity time, active days, gender, age, profile picture, skin tone, picture type, business-account status, and mapped WhatsApp number. The exported Excel is the authority for that task; not every record will populate every column.
Interpret each field independently. Activity time is not guaranteed real-time presence. Business-account status is not the same as verified business identity. A missing picture does not mean an invalid number. Age, gender, skin tone, and picture type are not identity verification. Missing values remain unknown.
When Full Format is the wrong task
If a decision needs only registration, select WS Registration Check on the AppShai WhatsApp Number Checker; its output is phone number and registration status. If service scheduling for existing customers requires time-related information, evaluate WS Activity Check. Collecting every profile field “for later” adds cost and governance risk.
Age, gender, skin tone, or image analysis deserves additional review: is the field necessary, do local law and contracts permit the purpose, who may access it, and when will it be deleted? Number checking should not become a shortcut to sensitive profiling.
A reviewable Nigeria workflow
- Select Nigerian CRM records with traceable provenance and a current purpose.
- Confirm +234 from source-country data, remove the national trunk zero, and clean punctuation.
- Retain an original-to-normalized-number and internal-ID map; put only normalized numbers in TXT.
- Run a representative sample of 20 to 100 records.
- After confirming format and columns, process the remaining permitted records.
- Download Excel, preserve the original, and reconcile a working copy.
- Store service, result, check date, and purpose without overwriting permission or opt-out history.
Validate the Excel result
Compare valid input rows with output rows, then review exceptions, duplicates, and mapped numbers. Spreadsheet software can convert long numbers to scientific notation or remove a plus sign. Set phone columns to text and reapply the same normalization rule before CRM import.
A small known-status sample can reveal mapping problems, but it cannot support an accuracy claim without a proper test design. Acceptance testing is for file, field, and join errors—not marketing statistics.
Common Nigeria number errors
- Duplicated country code: 234803… becomes +234234803….
- Retained trunk zero: the value becomes +2340803….
- Mixed-country assumptions: every record in a batch is treated as Nigerian without source evidence.
- Spreadsheet corruption: scientific notation, removed plus signs, or truncated digits.
- Missing becomes “no”: unknown, no result, and a confirmed negative are different states.
Frequently asked questions
Do I keep the zero after adding +234?
The domestic trunk zero is normally removed. 08031234567 becomes +2348031234567. Confirm against the source record and current numbering plan.
Can Full Format identify a Nigerian user’s purchase intent?
No. Intent must come from voluntary behavior, conversation, orders, or properly designed research. Number and profile-support fields are not intent evidence.
Can I start a campaign immediately after checking?
A check result is not marketing permission. Confirm channel and message-category opt-in, provide opt-out, and follow WhatsApp business-messaging requirements.
