# What is a WhatsApp QR code? A WhatsApp QR code is a type of QR code that contains a WhatsApp phone number or a WhatsApp message and allows users to easily initiate a conversation by scanning the QR code using a smartphone or QR code scanner. QR codes are two-dimensional barcodes that can be scanned to access information or perform an action, such as starting a conversation on WhatsApp. WhatsApp QR codes are created by encoding the WhatsApp phone number or message into the QR code using a QR code generator tool or software. The resulting QR code can be printed or displayed on a screen, and then scanned by a user to automatically open WhatsApp with the phone number or message pre-filled. WhatsApp QR codes can be used in a variety of applications, such as providing a quick and convenient way for customers to contact a business or for event organizers to distribute contact information to attendees. One advantage of WhatsApp QR codes is that they provide a simple and easy-to-use way for users to initiate a conversation on WhatsApp without having to manually enter their phone number or compose a message. In summary, a WhatsApp QR code is a type of QR code that encodes a WhatsApp phone number or message and can be scanned using a smartphone or QR code scanner to automatically open WhatsApp with the phone number or message pre-filled. They are a convenient tool for enabling users to quickly and easily start a conversation on WhatsApp in a variety of applications. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
