Quick Answer
For most business use cases, the essential vCard fields are full name, company, role, one primary phone number, one primary email address, and optionally one maintained website. Use international phone formatting, keep text clean and current, and avoid overloading the record with optional fields that do not improve the next step after the scan.
Field priority by importance
| Priority | Fields | Why |
|---|---|---|
| Essential | Full name, phone, email | Without these, the contact handoff is weak or incomplete |
| Strongly recommended | Company, title, website | These add business context and improve recall after the scan |
| Optional | Address, social profiles, extra numbers | Useful only if they support the actual follow-up workflow |
| Usually remove | Legacy fields, duplicates, stale data | They make imports messy and reduce trust |
Formatting rules that improve compatibility
- Use international phone format. It is more portable for global teams and reduces ambiguity across regions.
- Keep company names consistent. If the same organization appears with different casing or abbreviations, imported address books become messy fast.
- Prefer one primary number and one primary email. Multiple contact paths can be useful, but too many lower the clarity of the record.
- Remove placeholders before export. Dummy titles, empty labels, and old office details create a low-trust first impression.
- Test special characters. Names, accents, and multilingual addresses should be checked on real devices before large rollouts.
When more fields actually hurt
A common mistake is treating the QR code like a CRM export. That creates bloated contact cards that are harder to maintain and sometimes import unpredictably across contact apps.
- Sales teams often work better with one mobile number and one email, not five touchpoints.
- Recruiting and consulting profiles may benefit from a website or LinkedIn field, but only if those destinations are current.
- If a field is likely to change soon, it may be better left out until it stabilizes.
Team standardization checklist
- Define one approved company naming convention.
- Choose a standard phone format for every market your team serves.
- Agree on which fields are mandatory and which are optional.
- Test one exported record on iPhone and Android before rolling out to the full team.
- Review records whenever someone changes role, department, phone number, or domain.

FAQ
Which fields are essential in a vCard QR code?
Full name and one reliable contact method are the minimum. Company and role are usually worth adding because they improve context after the scan.
Should phone numbers use international format?
Yes. International formatting is more resilient for global teams and for contacts who may save the record in another country.
Is vCard 3.0 still acceptable?
Yes. It remains a practical choice for broad compatibility, especially when you care more about stable imports than niche field behavior.
Can I include multiple phone numbers?
You can, but the more options you add, the more cognitive load you create. In many cases one primary mobile number performs best.
