International numbers must include the country code to work in WhatsApp. A number saved without the country code will not be found.
| Country | Country Code for Number |
India | +91 followed by the 10-digit mobile number. Example: +91 98765 43210 |
USA / Canada | +1 followed by the 10-digit number. Example: +1 415 555 0123 |
UK | +44 followed by the number without the leading 0. UK: 07911 123456 becomes +44 7911 123456 |
UAE | +971 followed by the 9-digit number. Example: +971 50 123 4567 |
Australia | +61 followed by the number without the leading 0. 0412 345 678 becomes +61 412 345 678 |
Germany | +49 followed by the number without the leading 0. |
Common mistake: Saving +91 09876543210 (extra 0 before the number) instead of +91 9876543210. Remove the leading zero when adding international numbers.

Adding contacts in WhatsApp Business works the same as personal WhatsApp, save the number in your phone contacts and they appear automatically. WhatsApp Business has a few additional ways to manage your contact list:
Label new contacts: After adding someone, open their chat > tap the label icon > assign a label (e.g. "New Lead," "Existing Customer"). Labels help organize customer contacts in WhatsApp Business without needing a separate CRM.
Contact appears after they message you: In WhatsApp Business, when a customer messages your business number, they appear in your chat list even if you have not saved their contact. You can save their number from the chat (tap their number at the top > Add to Contacts).
For large contact lists (100+ contacts): Saving each customer individually to your phone contacts is not practical for businesses with large contact lists. Roklo lets you import a contact list from Excel and send WhatsApp messages to all of them, no phone contact saving required, no API approval needed.
Method 1 - Direct add (the person must be in your phone contacts):
Method 2 - Group invite link (works even without saving the contact): Generate a shareable link anyone can use to join the group. WhatsApp group link guide covers how to create, share, and manage group invite links, the fastest way to add multiple people at once.

Fix 1 - Grant contacts permission: Android: Settings > Apps > WhatsApp > Permissions > Contacts > Allow. iPhone: Settings > WhatsApp > Contacts > toggle on. Without this permission, WhatsApp cannot read your saved contacts.
Fix 2 - Refresh contact sync: Android: WhatsApp > three-dot menu > Settings > Contacts > Refresh. iPhone: close WhatsApp completely and reopen. This forces WhatsApp to re-check your contact list.
Fix 3 - Verify the number is on WhatsApp: Not every phone number has a WhatsApp account. The contact only appears in WhatsApp if that specific number is registered. Ask the person which number their WhatsApp is on, they may use a different number than the one you saved.
Fix 4 - Check the country code: A number saved without the correct country code will not be recognized. Edit the contact to include + and the full country code. +91 9876543210 and 9876543210 are treated as different numbers by WhatsApp.
Fix 5 - Update WhatsApp: Old WhatsApp versions may not sync contacts correctly. Update from the Play Store (Android) or App Store (iPhone) and restart the app.
Adding someone on WhatsApp is automatic once you save their number with the correct format, including the country code for international contacts. The QR code method is the fastest for adding in person. The group invite link handles adding multiple people to a group at once. For inviting someone who does not have WhatsApp yet, use the in-app Invite Friends option.
For messaging someone without saving their number, the wa.me/[number] browser link opens a direct chat in seconds. WhatsApp Business follows the same contact-adding process as personal WhatsApp, with the added option of contact labels for customer organization.
For businesses sending bulk outreach to a contact list without saving every number, Roklo is a free bulk message sender that handles how to send bulk WhatsApp messages from a browser, no saved contacts, no API, no per-message charge.
