Methods and systems for contact importing using a mobile device

1. A method comprising:

by one or more computing devices of a social-networking system, providing to a user of a wireless service provider a reference code identifying the user, wherein the user is associated with the social-networking system;

by the one or more computing devices, upon receiving the reference code by a mobile computing device of the user, providing an indication for the user to log in to the wireless service provider;

by the one or more computing devices, receiving first contact information for contacts of the user from the wireless service provider based on at least the reference code, wherein the first contact information is maintained by the wireless service provider;

by the one or more computing devices, identifying differences between the first contact information and second contact information maintained by the social network system; and

by the one or more computing devices, updating the second contact information maintained by the social network system based on the identified differences, synchronizing the contact information maintained by the wireless service provider and the contact information maintained by the social-networking system, identifying new contact information including new contacts based on the synchronizing, requesting a selection of the new contacts to be added to a social network of the user, and providing invitations to the selection of the new contacts to join the social network of the user.

2. The method of claim 1 , comprising providing the indication for the user to log in to the wireless service provider on the mobile computing device.

3. The method of claim 1 , wherein the reference code includes a QR code associated with the user.

4. The method of claim 1 , further comprising providing an indication for the user to provide credentials for the log in.

5. The method of claim 1 , wherein the log in by the user includes provision of a PIN by the user.

6. The method of claim 1 , comprising providing an indication for the user to log in to the wireless service provider on a desktop computer.

7. The method of claim 1 , wherein the reference code is scannable by the mobile computing device of the user.

8. The method of claim 1 , further comprising providing a progress bar to guide the user through a sequence associated with contact importing.

9. The method of claim 1 , comprising providing a first notice to the user on a desktop computer to invite the user to import contact information from the wireless service provider to the social networking system.

10. The method of claim 9 , comprising, after the user selects a link to log in to the wireless service provider using a mobile computing device, providing a second notice including the reference code associated with the user.

11. The method of claim 10 , wherein the second notice is automatically updated to reflect a current status of contact importing.

12. A non-transitory computer storage medium storing computer-executable instructions that, when executed, cause a computer system to perform a computer-implemented method comprising:

providing to a user of a wireless service provider a reference code identifying the user, wherein the user is associated with the social-networking system;

upon receiving the reference code by a computing device of the user, providing an indication for the user to log in to the wireless service provider;

receiving first contact information for contacts of the user from the wireless service provider based on at least the reference code, wherein the first contact information is maintained by the wireless service provider;

identifying differences between the first contact information and second contact information maintained by the social network system; and

updating the second contact information maintained by the social network system based on the identified differences, synchronizing the contact information maintained by the wireless service provider and the contact information maintained by the social-networking system, identifying new contact information including new contacts based on the synchronizing, requesting a selection of the new contacts to be added to a social network of the user, and providing invitations to the selection of the new contacts to join the social network of the user.

13. A system comprising:

at least one processor; and

a memory storing instructions configured to instruct the at least one processor to perform:

providing to a user of a wireless service provider a reference code identifying the user, wherein the user is associated with the social-networking system;

upon receiving the reference code by a computing device of the user, providing an indication for the user to log in to the wireless service provider;

receiving first contact information for contacts of the user from the wireless service provider based on at least the reference code, wherein the first contact information is maintained by the wireless service provider;

identifying differences between the first contact information and second contact information maintained by the social network system; and

updating the second contact information maintained by the social network system based on the identified differences, synchronizing the contact information maintained by the wireless service provider and the contact information maintained by the social-networking system, identifying new contact information including new contacts based on the synchronizing, requesting a selection of the new contacts to be added to a social network of the user, and providing invitations to the selection of the new contacts to join the social network of the user.
