Question

'...want'  and  '....want to'  which one is correct
'My wechat ID ****** you can add me if you want' and 'My wechat ID ****** you can add me if you want to' 
I'm not sure, which one  is  correct of these two sentences ?  Thank you in advance.

Answer

In common speech, both sound correct.  You are missing the "is" before your ID.  For example "My wechat ID is ****.  You can add me if you want/want to"
Another option would be "you may add me if you like" (Perhaps more polite).
