DIRECT ANSWER
What you should know
A plus sign communicates that a phone value is international. Preserve it as text all the way from the source export to the destination address book.
Before you begin
- Keep an untouched copy of the source export.
- Work on a small sample before changing a complete address book.
- Review the downloaded file before importing it elsewhere.
Why the prefix matters
The same digits can route differently depending on the country context. Removing + or a country code can turn a valid international number into an ambiguous local value.
Protect it through spreadsheets
Use text formatting for phone columns and avoid formulas that coerce the value to a number. In a CSV, quote values when a downstream program is known to infer types.
- Keep the source export unchanged.
- Normalize a copy with phone columns treated as text.
- Preview the generated VCF.
- Spot-check local and international examples after import.
Normalize only with a known country context
A formatter cannot safely invent a country code. If the source is ambiguous, preserve the original string and ask for the missing context rather than silently rewriting it.
