Where can I check my mobile phone number if I haven't received the e-invoice SMS?

Yes, you can. Where can I check my mobile phone number if I don't receive the short message of electronic invoice? I just need to look it up online. Electronic invoice is the product of the information age. Like ordinary invoices, they are distributed to merchants in the form of unified issuance by the tax bureau. The invoice number is distributed to merchants with national unified coding and unified anti-counterfeiting technology. The electronic invoice is accompanied by the signature mechanism of the electronic tax bureau.
